There are certain factors that the GATE aspirants need to keep in mind while preparing for the exam. We have formulated a few strategies opted by the previous year toppers that candidates may follow to ace the exam.
Candidates must start their preparation early by doing so, they will be able to compile all the necessary study material and create a proper plan that they may follow during their course of preparation. Preparing a layout and then working accordingly will cut-shot the time wasted while being confused about how to start their preparation
Another foremost step that candidates must do is to have a clear idea of GATE Syllabus that needs to be covered. GATE is a high-level exam and therefore, there is vast syllabus that candidates need to cover. In order to cover the overall syllabus without missing any topic, candidates must go through the syllabus provided on the official website of GATE 2020. Candidates must try to cover those topics first from which the possibilities of questions asked are higher.
Tabulated below is the GATE 2020 Syllabus for each stream along with the paper code.

Along with the syllabus, candidates must be aware of GATE paper pattern and its trending changes. Having an idea about the exam pattern prior to taking the final test will help them to solve the paper with ease. Though the pattern remains the same each year, the structure of paper may differ. An idea about the number of questions asked and the questions with higher weightage may increase the chance to score high. Go through the highlights of GATE Exam Pattern given below.
|GATE 2020 Exam Pattern Highlights|
|Exam Duration||3 Hours|
|Types of Questions||Multiple Choice Questions Numerical Answer Types Questions|
|Sections||General Aptitude (Common for all streams) Engineering Mathematics (Chemistry for XL Papers) Stream Specific Subject|
|Marking Scheme||1 Mark MCQs - ⅓ marks will be deducted for the wrong answer 2 Marks MCQs - ⅔ marks will be deducted for each wrong answer No marks will be deducted for unattempted question No negative marking for NAT questions|
The distribution of each topic in the paper will help a candidate in prioritizing the topic which needs to be covered first. Topics with higher weightage must be prepared thoroughly. It will be a good strategy to ace the exam. This could be done by going through the previous year question paper and analyzing the trending changes. Also, go through the section-wise weightage of GATE exam given below.
|Paper Code||Percentage Weightage|

Time Management plays a major role while preparing for the exam. GATE aspirants should utilize each second effectively. Proper time division for covering the syllabus, practicing sample papers and last-minute preparation should be done so that the candidate does not miss anything before attempting the paper.
Having a stronghold on the basics of the topics can help in performing much better in the exam. Candidates must have deeper conceptual knowledge on the frequently asked topics. The easiest way to keep command on basics is: Prepare short notes of formulas, concepts and compile it at a single place. Make it your habit of going through the short notes before starting your preparation each day.
Mock Tests are the best source for GATE preparation. If taken seriously, it has its own benefits that candidates may get to know while attempting the question paper. Once the candidates have covered all the syllabi, they must take as many mock tests as possible. Mock tests are similar to the final test that candidates will give. One mock test each day will benefit the candidates in the following way:

Ques. From which subject I should start my preparation?
Ans. In the starting, the first important thing is that should have your focus in the preparation only. So that you should start from the easy subject which you can easily remember this will help you to build your confidence level. If you choose the difficult subject it may ruin for confidence level which will later impact on your preparation strategies.
Ques. How many hours should I dedicate to my studies?
Ans. It depends upon your preparation. If you have done your subjects well during college time then you may study for 3 - 4 hours. If you are beginner then the extra effort will be needed.
Ques. Is it enough to prepare from a single book?
Ans. It depends on the subject, some subjects can be prepared well from one book. But the GATE Syllabus is such vast that some subjects syllabus is not covered by the single book. There you need various books for your preparation.
Ques. How much time is needed to complete the Syllabus?
Ans. It also depends on you and your preparation. If have give exam earlier also then you can prepare for it in 3 – 4 months. If You are a beginner then you may take up to 6 - 7 months for your preparations.
Ques. From which material I should Prepare?
Ans. You can use the following material for preparations:
