Hi friends!! Hope you must be having a wonderful day. After posting my Post GATE interview experiences (you can check them out here), I got responses from many students requesting me to post some preparation tips for GATE.So on popular demand, here comes my long post recounting my Pre GATE experiences.
Well, I remember my days before GATE as one of the most difficult and challenging times of my life; yet when I look back upon them I wonder how many things they have taught me which helped me consolidate my character and emerge as a stronger person.Nine hours of job followed by 2-3 hours of coaching on weekdays and wait! weekends were no relief. My Sundays were the worst; lasting from 6 am to 9 pm of studying :O ( 15 hours in a row!!). I am amused how I survived those times.The one thing which kept me going was my firm resolve to prove myself to the world and the ambition to see myself in a top IIT.
I will not define my preparation to be an ideal one. I didn’t study all the available material nor solve most of the practice problems and questions ( some of my coaching material was left untouched); but what I did study and solve was sufficient for my preparation.I am a person who believes in studying on my own without any coaching or tuition.But, things were different this time.Since I had to prepare with job, I decided to join a coaching institute which can keep the spirit of competition alive in me and provide me the required motivation needed for clearing any competitive exam. Also there will be some part of me feeling guilty if I paid a heavy price as coaching institute’s fees and still didn’t study seriously ( just a psychological trick 😉 ) For all those people who fall in the category of job+GATE, I want to say that preparing with job is difficult but not impossible.Try to prioritize your work.Keep some e-books on your office desktop and study them as well as some online resources ( provided links below) whenever you get time.Avoid distractions (I mentioned a few in my Introduction post).Remember if you work hard now, you can enjoy later.There will be many people to discourage you saying that GATE is useless, there is no use of MTech, why bother to leave a current job which is paying well, go abroad for MS, blah blah blah. It’s your ability to discard the noise and improve the quality of positive thoughts entering your mind. As it is truly said half of the battle is mentally won.Always be mentally strong and believe in yourself and what you are aspiring.
Ok, enough of pravachan from my side :P.Let’s be back on track. So, after deciding to join a coaching institute, I began a hunt for the same. Living in Hyderabad, I had lot of options to chose from ; but one of them was a clear winner based both on its past records and its location near to my office and flat.Yes, you guessed it right! I joined evening batch of ACE Academy located at Abids. The classes started from 16th or 17th July which was quite early based on my standards of preparation which I have been following throughout my life ( later I was proved wrong when I saw batches starting from March ).What happened later for the few months till GATE is as I have already mentioned above ( office+classes).After returning from coaching, I somehow had my dinner and dropped straight to my bed. Life was indeed hard but I was happy thinking that each passing day is bringing me close to my goal.I have been a topper throughout my school and college, but I can tell without a pinch of doubt that the hardest I worked and studied in my life was this particular period.
I will provide a subject wise description of my preparation below:( only EC – other strams having some common subjects can also see)
1. Engineering Mathematics: This was the first subject to be started at the coaching institute. I would say that this is one of the easiest and scoring subjects of GATE. It is easy to grasp and questions asked from maths are pretty straightforward. A word of caution: Do not ignore this and leave it till the last month for studying.The things I studied for my Engg. Maths preparation are:
- Higher Engineering Mathematics – B.S. Grewal ( problems on Stroke’s and Gauss Divergence theorem and some portions of statistics)
- ACE material and class notes.
Important topics: Stroke’s and Gauss Divergence theorem, probability, complex variables, linear algebra.
2. Network Theory: If you see previous years questions, you will find that this subject carries a lot of weightage. You also need its concepts in other subjects like Analog ( OPAMP based problems ) and Digital. Moral: Be sound in network theory. Practice a lot of questions and try to analyse them before solving.There can be many methods to solve one particular problem; chose the one which is convenient for your use.Before joining ACE, I had a feeling that I am good in network theory. But the classes at coaching helped in clearing my myth and solving some of my perennial doubts in this subject.My prep. included:
- ACE classroom material and notes ( this is excellent and more than sufficient)
Important topics: Transient and steady state analysis, Thevenin’s & Norton’s Theorems, Nodal and Mesh Analysis, Phasors, Maximum Power transfer theorem.
3.Control Systems: This is one of my favorite subjects. It carries almost 12-13% weightage in GATE. Practice and more practice is the key to success.Try to be fast and accurate while solving problems. Use shortcuts and tricks wherever possible.My preparation included:
- ACE classroom material and notes ( The teacher provided some amazing shortcuts to solve problems. The variety of questions included in the question booklet are too good not only for GATE but also PSU’s,IES,etc.)
- Control Systems Engg.- Nagrath & Gopal.( PD,PI,PID controller, lead and lag compensator)
Important topics: Time domain analysis, root locus, bode and nyquist plots, gain and phase margin.
4.Electromagnetic Theory: Well, this is a subject which most of the students of EC find the most difficult and annoying. The same was the case with me. I hated this subject since my college days. The long and complex formulas and equations just blew my mind off. It is only after coming to ACE that I appreciated the true beauty of the subject.The first set of classes laid the foundation for my rising interest in the subject.In my opinion, EMT is the most scoring subject in GATE as well as other exams like ISRO,IES,etc. Most of the questions asked from this are either direct formula based or application of basic concepts. If you are confident in this subject , rest of the subjects will be quite easy for you to prepare.Success Mantra: Revise many times and write down all the formulas as frequently as you can.Never ever take the chance of leaving EMT and writing GATE.You will be the biggest loser.My preparation included:
- Field & Wave Electromagnetics – David K. Cheng ( all topics esp. waveguides )
- ACE material and notes.( served mostly as revision of my concepts and formulas)
Important topics: Boundary conditions, transmission lines, maxwell’s equations,Poynting theorem,basic antenna concepts.
5.Communications: I am sure everyone of you knows the importance of this subject.It carries the maximum weightage in GATE and has a wide syllabus to cover. This subject is quite interesting and you need to be good in maths to be good in communications. My preparation of communication included:
- Communication Systems – Simon Haykins ( Analog Communications )
- Principles of Communication Systems – Taub & Schilling ( Digital Communications- more questions are asked from digital communication as compared to analog in the past 5-6 years)
- ACE classroom study material ( only for practicing problems and revision )
Important topics: Random variables ( one question sure), probability of error, FM, Noise, Matched filter, superheterodyne receivers.
6.Signals and systems: I was lucky to get a very good teacher for this subject who taught in a very intriguing way and challenged us to solve problems making us competitive enough. Success Mantra: Write down all important formulas and definitions in a piece of paper. One of the advantages of this approach is that it will help you relate concepts used within the subject making your preparation smooth and easy. My prep. included:
- ACE study material and notes (excellent material which is more than sufficient for cracking all sorts of competitive exams)
Important topics: All topics are important; questions on sampling and laplace transform are frequent.
7. Analog Electronics & Electronic Devices: These are the two most important subjects for GATE preparation and being an EC student you have to be very good in them not only for GATE but also for your future.I have clubbed them together as both are highly interrelated both content and material wise.You should complete electronic devices before starting your preparation for analog. Success mantra: Clarify your concepts and apply reasoning in every question.The more you read and solve the better you will become in these subjects. My preparation included:
- Microelectronics Circuits – Sedra Smith ( best book for enhancing your basics; read it only if you have time as everything is explained in very much detail which is not required for GATE exam; but will be helpful for your interview prep.)
- Electronic Devices & Circuit Theory – Robert L. Boylestad ( topics are explained in a simple and point wise manner)
- Integrated Electronics- Milliman & Halkias ( called the Bible of Electronics – is the best if you read from the beginning. You can rely on it blindly)
- ACE material – concepts were explained in a very unique and exam-friendly way( good for revision )
Important topics: OPAMP , BJT amplifiers, Feedback amplifiers, Diode based problems.
8. Digital Electronics: This is one of the most interesting and popular subjects among the students and truly so because it offers a logic based approach to problems and we don’t have to memorize any complex formulas or equations in this ( as opposed to many EC subjects). A word of caution: Don’t be overconfident.Questions asked in GATE may seem quite simple but will be tricky most of the times.My prep included:
- Digital systems Principles and applications – Ronald J Tocci
- Digital Design – Morris Mano
- Microprocessor Architecture Programming and applications with the 8085 – Ramesh Gaonkar ( for microprocessor )
- Digital Computer Electronics – Malvino ( microprocessor explained in a very short but effective way)
- ACE practice material
Important topics: Flip-flops, counters, logic families,microprocessor ( one question compulsory)
10. English and Aptitude: Most of us completely ignore this section. But, I tell you this can prove a deciding factor where either you or your competitor can score over and bring a better rank. I referred no material for this section. The practice questions and mock tests were sufficient.
Some Preparation Tips:
- Practice at least 10 years of previous GATE question papers. This is very important as it not only helps you identify your strengths and weaknesses but also proves critical for your time management skills.
- 45 days before the exam, solve a mock GATE paper every alternate day ( and it strictly means 3 hours).The environment should be the same as you will face during the actual GATE exam. Club this with revision of all subjects. Remember the last one month is very crucial for your preparation.
- Prepare subject-wise short notes for quick reference.This will prove very handy during revisions as well as interviews.
- If possible, enroll for a test series(preferably online as the final exam will be online). This will help you maintain the pace of your preparation and the AIR will give you an idea on where you stand. However, I will advise you not to take this rank too seriously and get disheartened or relaxed.This is only a prep. exam and not the final GATE exam which is your prime focus.
- Be confident of your preparation and solve questions with a patient head.I will advise you to attempt your GATE paper in three rounds.1st : easy questions which you can solve at one go; 2nd: average questions which require some thinking but can be solved; 3rd: difficult questions which require more time and thinking.This approach will gradually build your confidence in solving questions and bring out the best in you.
- Don’t take too much stress and worst, don’t get influenced by other’s preparation.Each individual has different levels of understanding and approach. So, never compare yourself with others. Plan your studies carefully keeping adequate time for practice and revision.
This was all I could tell you regarding my GATE preparation.I knew my prayers were not unheard when I saw my result ( to know more about my result read here ) which was just above my expectation :).I would like to thank my parents without support and understanding, it would have never been possible. I am lucky to have such amazing parents who are always ready to help and motivate me.The next token of thanks goes to my friends who always heard my constant whining and how I have studied so less till now ( this is part of my nature 😉 and still made me remember my strengths and how I can rectify my mistakes.I would also like to thank the some wonderful teachers and friends at ACE who helped clear my concepts and booked seats for me in the classroom (respectively );). Last but not the least, I would like to thank God and of course me( who did it finally 🙂 )
