During their mechanical engineering degree program,

During their mechanical engineering degree program, many of the students are usually interested in doing mini projects and final year projects related to design and manufacturing.  Here I have suggested a list of mechanical engg projects for students:
1. Design/manufacture a sugar dispenser: You will find many tea and coffee dispensers at different places. Why not introduce a sugar dispenser as well? This sugar dispenser can be used to mix sugar in a more hygienic condition with minimum sugar waste. In this mechanical engineering design project idea, you need to design a sugar dispenser with full automatic control. This sugar dispenser will be used to pour tea into cups and can be placed alongside tea dispensers.
2. Design a multipurpose chair/table: Design a multipurpose chair/table which can be converted to a table or a chair as needed. Using mechanical engineering design techniques you need to design this product which users can fold into a chair or even a table as required. This is actually 2 in 1 type product. This product if properly developed can also be sold in the market.
3. Design a machine to produce power from canals: Water in most of the canals has a lot of energy. Why not use this energy for some useful purpose? Think of some product or machine which you can install on a canal to generate energy and electricity from running water. This mechanical design project can be very useful in rural areas of developing countries.
4. Design a multi-direction wind turbine: Design a wind turbine which can operate in any wind direction but rotates in the same direction. Whatever the direction of the wind is, it must operate in same direction. These kinds of wind turbines are very useful in hill stations and mountainous areas where wind comes in from different directions at same time. So all this wind from different direction can then be used to operate this turbine in a same direction.
5. Design a robot for spraying: In this mechanical engineering design project you need to design a robot for spraying purposes using a remote. This is also related to robotics projects in mechanical engineering. Movement of robot can be defined and controlled using a robot.
6. Design a mobile phone holder for cars: In this design project, engineering students can design a product which can be installed on car doors or dash board and which is capable of holding mobile phones and charging them.
I have suggested these mechanical engg design projects after detailed discussion with industry experts and professors. Kindly discuss these projects with your college professors as well. Keep visiting this mechanical engineering vision website for more new and latest projects.

Thermal mechanical engineering projects (thermodynamics)

After proper guidance from senior professors and experts, i have created following list of projects :
1. Calculate heat generation and refrigeration capacity: This mechanical engineering project idea is related to thermodynamics and heat transfer. You need to calculate heat generation and refrigeration capacity within any factory or shopping mall or even in your own campus building. Then after performing complete analysis on these factors you need to suggest improvements in building design and other factors which will minimize heat generated and humidity within a building.
2. Make a steam powered rocket boat: Do you know how a rocket propels itself? Hot gases burn out and rocket propels further. Why not use this phenomenon in making a rocket boat which uses steam/boiled water or even hot gases to propel the boat onto water.
3. Manufacture solar powered oven and cookers: Design and manufacture solar powered cookers with more efficiency for use in remote areas of developing countries. This thermal mechanical engineering project is purely related to thermodynamics. Students who are interested in engineering projects related to thermodynamics should undertake this project in order to understand complete concepts of the subject as well as heat transfer.
4. Design and analysis of a virtual refrigerator: In this thermal mechanical project you need to Design a virtual refrigerator in any CAD utility and perform complete analysis using ANSYS or any other software on performance of using different refrigerants. This virtual environment will help save millions of dollars spent on making labs for understanding performance of different refrigerants used within refrigerators.
5. Design a fish aquarium with automatic control: In this thermodynamics project mechanical engineering students are required to design an aquarium for fish with automatic control of temperature according to the weather and temperate in the environment.
6. Automatic fire fighting robot/Machine: Design small scale robots or machines which can be installed in different buildings and shopping malls in order to avoid accidental fire in any building. This mechanical engineering project is related to thermodynamics and manufacturing courses. It will help save many accidents which cause great financial loss due to fire caught within any building during night.
I hope you will like these thermal mechanical engineering project ideas.

Automobile project ideas for mechanical engineering students

I would like to share some automobile project ideas for mechanical engineering students:
1. Improvements in diesel engine for less emission of CO2: Obtain a used diesel engine from your engine lab in your campus or you may also get it from any sponsor. You task is to measure the percentage of hazardous gases which emit from engine exhaust then you have to reduce that percentage to a minimum level. Think about the improvements which you can make into that diesel engine which can reduce emission of dangerous gases which cause pollution to the environment. This is a hot issue and research topic these days. Get yourself involved into this research and maybe you can reduce a little bit of it and play your part in saving the world. You can work initially on reducing percentage of CO2 emitted or you can choose any other emission gas. This project will help you in understanding all diesel engine working procedures in detail. Hint: Record you readings in excel sheets and develop macros to sort out data in a desired form.
2. Create a device or make changes in speed meter to warn next oil change required: Changing engine oil and filter on time helps improve efficiency and performance of an engine. Exactly when a car owner requires changing engine oil? There is no such device to warn next engine oil change. It’s usually done manually. So in this mechanical engineering automobile related project, you can manufacture a device to warn next oil change required. This will help improve efficiency of the automobile.
3. Create a low price car jack: Create a low price and small scale edition of a hydraulic car jack in order to minimize human effort and risks. Most of the car jacks used these days are scissor car jacks with mechanical threads which require a lot of human energy and cause many accidents frequently. So in this automobile project you are required to manufacture a small scale hydraulic jack for cars which are cheap to buy and require less effort to use. Fluid energy can be used which will minimize human effort to a great level
4. Design/manufacture more efficient mudguards for cars: In this mechanical engineering project idea, you need to design special mudguards with improved efficiency. Use any mechanical engineering software or CAD/CAM setup to design these mudguards. Make them more elastic and more strengthened to survive from any hard materials on roads or in mud
5. Create a small carriage for shopkeepers or grocery store owners from bike engine: Convert your motorcycle into a more useful carriage for medium shop businesses. Take into account all the weight requirements and safety measures while making this device. Perform complete structural analysis before finalizing your product. This is very helpful for developing countries. It will provide a great carriage for small to medium scale shopkeepers to carry their stock from market with less fuel consumption and at economical cost
6. Create a device to insert into exhaust system of a car to convert hazardous gases into environment friendly liquids and gases: In this mechanical project which is related to automobile exhaust system, you need to create a device which can be inserted into exhaust section of any car. This device should be capable of converting CO2 and other hazardous gases into environment friendly liquids or gases through some chemical reactions.
I hope you like these project ideas for mechanical engineering students. Discuss these automobile projects and ideas with your professors and advisors in your colleges and departments and start working on them. You will find these projects very helpful in understanding mechanical engineering and automobile engineering concepts.

Final Year Mechanical Engineering Projects

Here I have compiled some great ideas for final year mechanical engineering projects at undergraduate level. These final year mechanical engineering projects are just an idea of what you can do. You can always increase or decrease the scope of a project and make any changes according to your requirements.

DIFFERENCE BETWEEN AN ENGINEER AND ASCIENTIST FROM JAZIB SAEED KHAN'S BLOG

Engineer vs scientist - Difference between an engineer and a scientist - “I always wanted to be an engineer. And today as I see the magnificent artifacts that have been created by me I feel so lucky that I landed in a profession of my choice”. Well these are the words of a random person who happens to be an engineer by default. And believe  me if he were a scientist, he would have said the same thing. And so the hot point is: we really never know what makes an engineer different from a scientist.
Ironically people differentiate scientists from engineers by the level of personality they own. Engineers are often regarded as cool people with highly paid jobs who have nothing to do in the world but to make all the important decisions. Scientists on the other hand are regarded as the hapless
people who spend most of their lives with lab rats thinking over the issues that have nothing to do with a common man. This is the main reason most students want to take up engineering as the future
profession although they never realize that engineering is a multifaceted endeavor and they will have no exposure towards it until the end of the high school. And this happens to be the most important reason that most people never realize that a scientist and an engineer are indeed very different with different aims and indeed different priorities.
Differentiating engineering from science is a matter of how we look at the two professions in the real
world. An engineer’s priority should be to take up real world challenges and complete them in real time so that people may get the desired results and benefits. So in a way, we can regard that an engineer is closer to the common man than a scientist. It is just an opinion not a well established fact.
A scientist on the other hand should have the insight to perceive the upcoming future. And that is the fun part. A scientist mostly lives in a virtual world full of random and abstract thoughts that combine to form a solution. An engineer on the other hand lives in a real world that we all can see and feel. And that is the main reason that most of the work done by the scientist does not become inevitable at once.
Engineers often argue that their job is more innovative than the job of an average scientist who has to live with a bunch of lab rats all day long doing nothing. Well this perception is absolutely wrong. Inevitably engineering is a very versatile profession but innovation is just a part of it. A scientist on the other hand lives merely on innovation. Working in a virtual world is no easy task which requires loads of innovation in store.
Sometimes it is very difficult to draw a clear boundary between the two professions. Both have contributed immensely towards the development of this world. And it would be true to say that both are the wheels of the same car. Instead of discriminating them, we should try to bridge the two professions so that the world can really see what happens behind the scenes. I hope this article gives
you a good idea about difference between an engineer and a scientist.

Problems faced in your final year project and ways to avoid them

Your academic project would be a demanding, but an exciting learning experience. However, it is not without problems which, if not identified and addressed, could seriously effect the final result and ultimately reduce your marks. Here we mentioned some of these problems and how to avoid them
The “Overachiever” Problem:
A common problem is selecting a topic that is far too ambitious for the allotted time.   Remember that you have only a few weeks to finish the design, development and testing of your project. Be careful not to select a topic that is unrealistically large.  This can lead to frustration as well as errors caused by “cutting corners” and hurrying through the implementation.  Discuss with your supervisor the scale of what you are planning.  If he or she thinks it may be too large, consider implementing the project in stages, each complete in itself.  When stage I is working move on to stage II.  If you do not finish stage II, however, you still have a functioning system.
The “Do It Tomorrow” Problem:
The project weeks alloted for completion sounds like a long time, but it goes by quickly.  You need an implementation schedule that allocates reasonable amounts of work throughout the entire semester. Then you must stick to that schedule.  Don’t be tempted to postpone work on the project because your due date seems so far off.  All that happens is that during the final few weeks you rush madly to get something working, and project implemented in a rush rarely works correctly!
The “Sleeping Member” Problem:
In the ideal world, all team members have equal ability, equal interest in the problem, and work equally hard.  In the real world that may not happen.  You may have one (or more) team members who do not carry their share of the workload, not because of a lack of ability, but rather lack of interest or motivation.  This is a serious problem because, although part of your marks is based on each individual’s effort, another part is based on successfully finishing the project.  A non-contributing team member can slow down or prevent completion of the work.  If you have a teammate who is not doing his or her share of the work, talk to them and stress the importance of everyone doing their job.  If this does not solve the problem then talk to your supervisor.  Don’t let the failure of others prevent you from completing the work and receiving good marks.
The “Poop Out At The End” Problem:
You have worked hard for many weeks to complete the project. You have spent many late nights and chased down hundreds of bugs, but it is now working, so are you done?  Absolutely not!  The project evaluation is not based only on the programs you develop but also on your written reports and oral presentations.  Even though you may be “burned out” from implementation, remember there is still work to do. Don’t produce a poorly witten paper or give a poorly organized presentation.  That will negate much of your good work. Put in the time needed to prepare both a well written, high-quality final report and a well organized, polished presentation. A good job on these last steps will insure that you receive the marks that fairly represents the work you have done.


Tips for Perfect Final Year Project

For an effective project, it is advisable to carry out the following activities
  • Defining the objectives of the project.
  •  Acquiring background information about the problem and its possible solutions.
  • Establishing the criteria by which your solution(s) to the problem will be judged.
  • Determining by what process the work will be carried out.
  • Planning the detailed phases of the project.
  • Adopting one or more design methodologies.Analysing requirements.
  • Using (or constructing) tools.
  • Construction of one or more artefacts (hardware, software, document).
  • Evaluating your solution to the problem.Reporting on your work.


    Whatever the nature of the problem you set out to solve, the conclusion of your project should be whether you solved it successfully or not.

Moment: It is the amount of moving effect which is gained for action of turning force.
Stress: It is the force that can prevent equal & opposite force. That means, it is the preventing force.  If one force acts on outside of a material, then a reactive force automatically acts to protest that force. The amount of reactive force per unit area is called stress. e.g. Tensile Stress, Compressive Stress, Thermal Stress.
Strain: If a force acts on a substance, then in that case if the substance would deform. Then the amount of deformation per unit length of that substance is called strain.
Spring: It is one type of device which is being distorted under certain amount of load & also can also go to its original face after the removal of that load. Its function:
  • To store energy.
  • To absorb energy.
  • To control motion of two elements.

Viscosity:
  • Dynamic Viscosity: The amount of resistance of one layer of fluid over other layer of fluid.
  • Kinematic Viscosity: It is the ratio of dynamic viscosity to density.
Buoyancy: When a body is immersed in a liquid, it is lifted up by a force equal to weight of liquid displaced by the body. The tendency of liquid to lift up an immersed body is buoyancy. The upward thrust of liquid to lift up the body is called buoyancy force.
Bernoulli's Equation:
P/γ +V²/2g +Z = Constant
Where, P = pressure,V = velocity,Z = Datumn Head
Devices for fluid:
  • Venturimeter: It measures discharge of fluid.
  • Notches : It measures discharge of fluid.
  • Orifice meter: It measures discharge of fluid.
  • Pitot tube : It measures velocity of fluid.
Mach Number: It is the ratio of the velocity of fluid to the velocity of
sound.
M=1 ----------------- Sonic flow
M> (1-6) ----------- Super-Sonic flow
M>6 ---------------- Hyper-Sonic flow
Fluid discharge/Fluid flow: Quantity of fluid flowing per second. (through a section of pipe/ through a section of channel)
Q=AV
where, V= velocity of fluid,A= cross-sectional area of pipe/channel

Amount of entry aiy if increased, then must be engine speed will increased. Amount of air  will be increased by increasing inlet air density. The process of increasing inlet air density is supercharging. The device which is used for supercharging is called supercharger.Superchargeris driven by a belt from engine crakshaft. It is installed in intake system. Turbocharging: Turbocharging is similar to the supercharging. But in that case tubocharger is installed in exhaust system whereas supercharger is installed in intake system. Turbocharger is driven by force of exhaust gas. Generally, turbocharger is used for 2-stroke engine by utilizing exhaust energy of the engine, it recovers energy otherwise which would go waste..
Governeor: Its function id to regulate mean speed of engine when there are variation in the load. If load incrases on the engine, then engine's speed must decrease. In that case supply of working fluid have to increase. In the otherway, if load decrease on the engine, then engine' speed must increase. In that case supply of working fluid have to decrease.Governor automatcally, controls the supply of working fluid to the engine with varying load condition.

CAD/CAM COURSES

In general, there are three program options for mechanical CAD students, including certificate, diploma and 2-year degree programs. Certificate programs are frequently two semesters in length and designed to train entry-level mechanical CAD operators. There are also certificate programs that require fewer credits to complete, which are designed for students with engineering backgrounds.

Mechanical CAD diploma programs include a few general education courses along with CAD and engineering design courses.  Associate's degrees in mechanical CAD require an average of 70 credits and include general education, mechanical CAD and other technology courses. An Associate in Applied Science in Mechanical CAD is for students who want to become professional mechanical drafters.
List of Courses
The following courses are commonly offered in mechanical CAD educational programs. Beginning CAD Course This foundation course teaches students to operate CAD software and hardware. Traditional technical drafting skills, including freehand sketching, are reviewed. Basic CAD skills are introduced and used to create 2-dimensional representations. Various software packages, including AutoCAD, are also taught.
Mechanical CAD Course
In this course, instructors introduce CAD techniques for mechanical drafting, building on the skills learned in the beginning CAD course. Mechanical CAD students create detailed engineering drawings using CAD software such as ProE. Industry standards for engineering design, including geometric dimensions and tolerance standards, are incorporated in class work. Computer Graphics for Engineering Course Topics covered in this course include creating 3- dimensional graphical representations of mechanisms. Students use applications such as animation software to view engineering graphics. This is an introductory course completed in the first semester of study in a 2-year program. Manufacturing Materials and Processes Course Properties of various manufacturing materials are surveyed in this course. Processes used to engineer products, such as forming and molding, are also covered. Specific materials studied include metals, plastics and ceramics. This course is a prerequisite for a course in machine design.

Machine Design Course
Students study the function of individual machine components and then design each component using
CAD software. Coursework concentrates on material choice, precision calculations and cost estimates. A portion of the course is focused on the inter connectivity of mechanical elements such as
belts, bearings, cams and shafts, in machine design.

Physics and Materials for Mechanical CAD
Operators Course
In this course, students study the physical properties of materials and material performance under certain stressors. General physics topics such as inertia, stress and torque are reviewed. This course is normally completed near the end of a 2-year program. As at the first step I have try to list all the CAD software. If I am missing some software to mention, than surely you can help me by informing me about that CAD, thermal software.

Motivate yourself for Gate or future!

By Expert..

1. If you show some guts to open up by not hiding behind "anon" - may be some one would have noted your situation and might have assisted you.

2. The moment you don't get a job, you people feel that you are untouchable. If that is what you believe how outsiders can understand you?

3. You are just 23- ( believe me if you can) when I was 45, a mere commerce graduate had two
children - I left the job to move back to my state - but without a job for 1 year. Then I just invented myself - and changed not only the horses but also the entire vehicle - and migrated from accounts to advertising.

4. You have not got GATE, and you are an instrumentation engineer and you got a break in employment and you feel and decided that you have
been fucked up.

5. Did you ever do masturbation? After doing it, did you ever feel guilty of doing it? And after a week you did it and enjoyed it and after its over you feel guilty about it ... it's a unending story.

6. I am afraid you young people should learn lot from Congress party. You can not be a AAP member and still want to survive in this society.

7. There are no Sages or Sri Rama in this society and we are all in a kind of society where we make up ourselves to get our daily bread.

8. The HR manager is cheating telling you in his company - only the real worker will be rewarded;
The management cheating explaining that the sky is the limit for real performer.
The Banker is cheating that they have money to loan you;
The team manager is cheating by telling that all the team members are equal to him. And we - as an individual - are unable to tell simple lie for our own life sake.

We tell lies to our girl friends and to our parents but when it comes to the job, we want to be naked there.

9. Stop telling in resume that you have a break ( not GAP) in employment. So after two days you will believe in your resume. You search some thing - some idea, some clue to cement that "gap". And re write the resume.

10. Do not show your or explain your strengths and weakness etc., Add a good convincing creative covering letter.

11. Being instrumentation engineer - you should look for job titles like " Team manager, assist manager - commercial, or purchase or design or Site Engineer of any trade, or else get back to e commerce ( not a software job)

12. Don't get fucked up by drawing circles and boundaries around you.

13. Have some flexibility and look beyond that instrumentation and GATE.

14. There are half a billion people with out IIT or IIM
or GATE. And they are happy.

15. Do not spend too much time on FB, delete your resume from Linked In.

How to study smart not hard?

Why is it that some students study really hard, but aren’t the best in their age group or get “only” average grades? And why is it that there are other students who do not even invest half the amount of time and effort into their studies, but get good or even outstanding results?

Intelligence certainly plays a role. But: The way you study can make or break your success at school/
college/university. My recommendation is to study smart, which can help you to save a lot of time  that would have been lost with unfocused attempts of “studying hard”. This article is, however, not intended as an excuse for students not to study at all. You will have to invest the proper amount of time for studying, there’s no way around. But, this article guides you on how to make the most out of the time you invest for studying. This article’s goal is to enable you to reduce the unnecessary parts of your studies and to focus on the important.
When I started studying, I was shocked to see many of my fellow students rushing into the library only to leave with seven or more books in their hands. That’s what I call ambitious. Many of them had lent every single book our professor’s had commended – sometimes up to 4 different books per  subject. Inclusively the script for each subject, it became a massive mountain of learning material (for them). For a very short time, I was a little frightened by their eagerness, but I held on to the decision of keeping my focus on the important. I kept it simple, lent two books I really needed, and in the end – I got the same and often better results in the examinations than the “overachiever”-crowd.

How did I do it? I studied smart and only periodically hard.
How to study smart not hard?
And how to avoid studying for so long?
This article is partitioned into three parts. 
Part A) Preparation and
Part B) Mindset focus on the organization of information that makes it easier for you to recall.
Part C) is the main part of the concept of “studying smart”.
A) Preparation
1. Get a study game plan.
You want to study smart, right? Hence, it makes sense not to approach your work in an unfocused, undirected way. Don’t dive head first into the topic. That’s the way that would actually cost you a lot of time. Instead, create a study game plan where you specify the day you begin to prepare for your exams create a daily schedule of tasks you want to accomplish during exam preparation create a detailed to-do-list , (keep a close eye on what is really important) enumerate the books you need to read (better: just the important sections you really need to know for the test) itemize the various tasks and exercises you want to do for preparation.
Depending on the difficulty of your exams and how many weeks and months you have for studying,
you could also categorize the weeks/months for preparation into different phases, from
I. basic refreshment of knowledge ,
II. studying, revision and exercise to
III. intensive cracking down – social life on hold.
How to do it the smart way?
A clear goal that you pursue gradually with your plan helps you to avoid many extra- hours, but it also allows you to direct your focus on the important.
2. Summarize.
I’ve had many exams about the content of an entire  book, most of these books in the range of 500-1200 pages. And even if you have only some chapters from a book/journal to read for the test, I highly  recommend you to create summaries, while working through the book. That way, you establish the fundament on which you can build upon, during the upcoming study phase, without having to read the book all over again. But you also train yourself to quickly identify the key statements in large texts that are very likely to be tested in the exam. As a consequence, it’ll be easier for you to skip large amounts of irrelevant data, while sifting through the book.
3.Separate the wheat from the chaff.
While you listen to a lecture or read through a textbook, give the  following a try:
Separate  continuously information that is important (“ Could this knowledge be tested in an exam? ”) from the unimportant (“ Is my teacher digressing or listing irrelevant data? ”).
Take notes of the important points your professor/teacher talks about and add annotations to your script or lecture notes.  Making these important additions to your script will help you at a later time to grasp important coherences.  You can also highlight important sentences or passages from the text, so that you can easily avoid reading through large amounts of unimportant data in your script.
B) Mindset
1. When you study, give 110%
When I went to school, I almost always had to study for long periods of time in order to memorize and understand given contents. The big mistake I made  was to study hard and for long periods of time, but I was not always focused on what I did. I got distracted by my mobile phone, the internet, TV, radio, telephone, friends or any other amusement one can think of. Nowadays, when I study I always give a 110%; I reduce distractions to a minimum and give my very best to avoid procrastination. I may have a time limit of 1-2 hours, but I want to make use of that time as much as possible. Thereafter, I have even more leisure time.
How to study smart:
When you study, do it in a focused and proper way, avoid any kinds of distractions and use the time you have to the maximum!
2. Continuity
Doing all-nighters some days before your examinations will not only exhaust you to a large degree, but will also force you to rush through the data, in place of studying properly. Instead of opting for all-nighters, consider spending half an hour after each day at university with post-treatment, i.e. reading a chapter in the book, making a summary  or doing some exercises. All this preliminary work will help you to spend more time with studying (during your exam preparation period), instead of having to engage with all kinds of inefficient tasks, such as extracting data from your books, trying to
grasps (arithmetic) operations and building an understanding etc.
Why is that smart?
If you already did the groundwork during the term, you’ll be able to focus a lot more on smart ways of studying.
C) The main part of “ studying smart”
1. Don’t try to memorize, understand!
One of the major mistakes I made – when studying hard not smart – was to learn by heart, which is really time-intensive. Rote memorization is fine and dandy if an upcoming exam requires you to reproduce what you have learned word for word. But the higher you rise in the educational system, the less important will it be to memorize and  reproduce, as your understanding and the ability to draw consequences will be tested instead.
In most cases, memorization corresponds to studying hard, not smart. Focus your attention on the understanding and comprehension of the knowledge that is taught.
But: How to understand complex topics?

Establish links and associations
Information becomes knowledge through connections. If you cannot relate to a complex topic, it’ll be very difficult to understand it. But, when you discover similarities and link new knowledge with concepts that you already comprehend, understanding the matter becomes easier. Try to spot ties between different topics and establish links between concepts that overlap.
Studying smart can help you to save a lot of time Imagine the subject matter as vivid as possible. Instead of recognizing the fact that the material you study consists of numbers, words and sentences,
think in pictures (headword: visually thinking). By doing so, you direct a movie in your mind that will help you to memorize facts faster and for a longer period.
What you basically do is the association of emotions (in the form of pictures) with rather unemotional data. It is difficult to memorize the numbers “483215”, but if you link each number with a picture and create a funny story out of it, it will be very easy to memorize the number-combination for a longer period of time. [By the way, this is THE memory trick artists use to memorize seemingly- indefinite number combinations.]
Emotions
Connecting emotions with your subject will greatly help you to internalize the topic. Have fun while studying! It’s for a fact that remembering things we  associate intensive feelings with is by far easier.
Also, if you’re really interested in a subject matter, learning becomes a lot more joyous. Once you manage to become curious about your subject and develop an interest in it, you’ve made an important
step towards a smarter way of studying.
Simplification through analogies
In school and university you’ll be confronted with various complex facts and circumstances. Make
use of analogies [= comparisons] and try to compare a very complicated issue with a more simplified one, which makes it easier to understand the bigger picture of that which is taught.
Simplification through patterning
While you study, make sure to pay attention to continual patterns within the subject matter that occur again and again. By noticing and understanding these reoccurring patterns, you begin to understand the framework on which the topic is constructed. Once you have a good overview of such a framework, the acquisition of new information that is based on the same pattern will be a lot less difficult.
Make use of acronyms
If you’re confronted with difficult, specialist words,  names or formula, an acronym can be an excellent aide-memoir for the memorization of the word or formula. Take for instance the rather simplex name “Enhanced Health and Usage Diagnostic System”. It’s acronym is “EHUDS”, which sounds like “e- hud’s” or “e-hat’s”. All you have to do now is to think about electronic hat’s and you’ll most likely be able to come up with the acronym “EHUDS”, from which you can rebuilt the original name.
2. Keep the bigger picture in mind
The constructing of a car can serve as example of the learning process. Your professor supplies the “know how” during his lectures, for instance the  detailed knowledge how an engine works. The textbooks and other learning materials supply you with the chassis, frame, tires and bolts. But, it is up to the student to make use of the know how, in order to use it for the combination of the delivered material. It’s the student’s job to put the car together and to keep the bigger picture of what is taught in mind.
If the student stubbornly tries to memorize the position of each part in the car, he/she will not be able to (re-)construct a car from a thousand of individual parts. Memorizing the different names of each part will not help either.
Only by keeping in mind that the know how and material are at one’s disposal for the creation of a
car, the student can effectively prepare for an upcoming test.
3. Perfect your type of studying
There are basically four basic types of studying: Visual, Auditory, Emotional and Kinesthetic.

1. Visual Learners: A visual learner studies most effective when the learning material is depicted in a visual way, e.g. in the form of charts, maps or brainstorming.
2. Auditory Learners: An auditory learner studies most effectively by hearing the information, for instance in a lecture or by recording their own words.
3. Emotional Learners: An emotional learner studies most effectively by associating feelings, emotions and vivid images with the information.
4. Kinesthetic Learners: A kinesthetic learner studies most effective when the information can be experienced and felt, i.e. via “learning by doing”.

Effective Study Methods
In order to study in the smartest possible way you need to discover which type of studying you prefer.
Once you know what works best for you, align your process of learning to make the most out of it.
Students that are mathematically talented should put their notes into spreadsheets, graphs and charts; kinesthetic learners imagine the learning material as vivid as possible; linguistic learners discuss the material with others or record their voice while reading the subject out-loud, etc.
