What is GATE?

Introduction

Graduate Aptitude Test in Engineering (GATE) is an All India Entrance Examination conducted jointly by IISc and seven IITs, every year in the month of January/February. The GATE score/Rank is used for admissions to Post graduate Programmes (ME, M.Tech, MS, direct PhD) in IISc, IITs and other prestigious Institutes / Universities in India, with financial assistance provided by MHRD. The GATE Score may also be used by PSUs for recruitment of candidates for prestigious jobs with attractive salary packages. Some of the PSUs which use GATE score for providing jobs include BARC, BHEL, IOCL, HPCL, NTPC, Power Grid, NHPC etc. GATE exam primarily tests the comprehensive understanding of the candidate in various undergraduate subjects in Engineering. The GATE score reflects the relative performance level in a particular branch. GATE score is valid for three years.

When to start your preparation for GATE?

Many would say that 3 to 4 months of serious preparation is enough for getting an under 500 AIR but keeping in mind the intense competition that is increasing year after year, it is suggested that you start your GATE preparation at the earliest.

How to prepare for GATE?

In order to crack GATE, you must first go through the entire syllabus word by word. Read and remember every topic of every subject that is mentioned in the GATE syllabus. You must know, very clearly, what to study and what not to study. 

Once you are thorough with the GATE syllabus, you are ready to begin your preparation for GATE.

It is very important for you to have a study plan if you want to get a good score in GATE examination. Most of the previous GATE toppers have followed the steps mentioned below in one way or the other. You need to do the same if you want to achieve what they have achieved.

1. Get previous years solved question papers for GATE

You must make sure that you have access to solutions of previously asked questions in GATE. There are a lot of options available in the market. Get your hands on any one of them. This you must carry with you all the time. You need to refer to it again and again. 

2. Analyse the paper trend

Every exam has its own trends and patterns. Refer to the syllabus and previous years papers and analyse the paper pattern of the GATE exam. All subjects don't carry equal marks in GATE. There are few subjects from which more number of questions are asked. Similarly there are few topics in every subject from which questions are being asked on a regular basis every year. After performing the above mentioned analysis, you will have a very good idea of the latest GATE paper trend.

3. Make a priority list of subjects and topics

Based on the marks and preference given to various subjects, decide what subjects you need to give priority to. Do a similar exercise for topics inside a particular subject. Given the vastness of the syllabus, it is very important for you to perform this exercise and create a priority list of subjects and topics. 

4. Allocate realistic time to topics and subjects

You must allocate realistic time to every topic of every subject based on their priority. Try to distribute your time so that you cover the top three topics of every subject first and then move down to subjects and topics of lesser priority.

5. Read, practice and revise

Read a topic and then solve the previous years questions asked from that topic. Do it for every topic of every subject. Stick to a time table, read the chapters, solve the previous years questions and take tests periodically to enhance your performance. Make sure that you revise the difficult topics and subjects periodically to optimize your efforts.

6. Finish your preparation well in advance.

You must make sure that you follow a time table that allows you to complete your preparation about a month before your actual GATE examination. You must use this last month to get ahead of the competition by solving as many questions as possible, taking as many mock tests as you can and working as hard as possible on your speed and accuracy. This is the step majority of the aspirants fail to take. Ensure that you follow this last step and rest assured that you will succeed in the GATE examination.
