GATE Study Planner Computer Engineering(CS)
Introduction
Hi Warriors,
Please find a comprehensive GATE Study Plan for your GATE exam 2021 preparation. The number of hours considered in this planner is 3 hours per day (on an average). You can adjust number of hours as per your convenience. For instance, if you see the Master planner below, you will find we need approx. 220250 hours for completing StageI. So if we study 3 hours, on an average, for 90 days = 270 hours, we can easily cover what’s given in the document.
Note: This plan is designed in consideration with students who have got top 100 ranks in GATE or any national level exam in the past few years
A similar plan is followed by many exam toppers and is highly recommended by most of The top faculties of the country. You will realize while going through it that a lot of research is gone In to make it helpful to you.
The following document contains :

Total Hours  254  357  286  125  140 
2. Flow of Studies for Any subject:
 Notes
 GATE que for past 10 years topic wise
 Topic wise test on aspiration.ai
 Subject tests on aspiration.ai
 Extra practice que + revision of subject
3.How to Make Notes:
 If you attend lectures of any faculty through GATEFLIX then you can easily make notes. If you haven’t done so, go to online videos to do so. You may also go to Youtube: Khan academy, Nptel or the latest and most popular are Gateflix videos.
 Make notes neatly as they will be very very useful while revision in the last 30 days. Use 3 colour pen to indicate important, very important and very very important concepts.
 Make a separate handbook for formulas. In exams 40% questions are direct formula based or implied formula based. Problem with students is that they tend to mix up formula. If you have this handbook of formula ready and have revised the things at least 2 times , I can guarantee you the 40 % marks.
 Don’t Xerox someone’s notes because the moment you write yourself then you can memorize the concept for a longer duration.
 Leave one page Space after 2/3 pages or after every major chapter. This is to ensure that if you come across any vital formula or Information or short trick while referring tests or reference book later then you may place That information in these spaces.
4.How to do a Test Analysis:
 Any test( Online or offline) need to taken in time frame.There is No point in taking the test without a time Limit.
 Don’t take any test without revision of Notes of the syllabus covered in the test. It will be a wastage if You just randomly take a test.
 Once the test time is over, don’t jump to answer Solution . Check the answer key and get To Know your score.
 Now follow a 3 stage process .
Stage 1: Go to the right ones and check whether you were confident of answering that question . If the answer is “yes” check the solution given in order to see which method was better( yours or the given in Book or online portal ). Adopt the best you like.
Stage 2: Go to questions which you got wrong. Try to fight with the question that why you got it wrong without looking at the solution yet. Try 3 or 4 times by rereading the question or even refer notes. Maximum time it’s a silly mistake. These silly Mistakes can’t be zeroed but can be reduced by practicing more .Refer notes again if needed. In case you are still not able to click after a lot of Slumber, try to open the solution and check your mistake. If it was a new concept to you, add in the void space you have kept in your notes. This will help to solve similar question again.
Stage 3: Now the turn of questions which are unattempted.This could be due to
 Not knowing The concept or due to lack of time. If it was conceptual ignorance , go to your faculty ( many online live class teachers are available , In case you don’t have one)and learn the concept.
 It was a lack of time issue try now and solve it. If you are taking a lot of Time try to memorize few steps so that if it appears in exam you will be able to do it fast. Other students might leave such question in exam , But you will probably dare to attempt such and score more.
 The key to successs in any entrance exam is solve More , analyse more. In each subject you should Solve almost 1000+ questions including past year Actual Exam questions, topic wise test, subject test and mock tests.
5. How To do Revision:
 Well this is dependent on the way you have prepared notes and how effectively have you done the Test Analysis.
 Go through the whole cycle again in this revision phase like NOTES > GATE QUESTIONS > Topic test > Subject Test > Extra questions (if any ).
 While Revising, don’t solve Each and every question from notes or tests. Try To randomly pick 20 questions from different pages or test( purely random) . If you are able to recall the logic of 16+ then you are good to go ahead. If you are Not able to solve more than 10 questions then it’s a re revision time. Follow step 2.
 Try to have a bird eye view and See topics on which questions Are asked again and Again. Star mark them for making revision 2 and revision 3 effective.
6.SUBJECT WISE PLAN:
Below given is a detailed execution of the GATE study plan which carries subject wise indepth action plan. In this artificial intelligence of GATE Study Planner, you will find:
