How to Calculate Score Using GATE answer key 2021
Using the answer key of GATE 2021, candidates can calculate probable scores following the below steps:
Calculate the total number of correct answers and allocate marks accordingly and then calculate the overall marks.
The candidate has to tally the total negative marks for wrong attempts. (Only Multiple Choice Questions (MCQs) will have negative marking. There will be no negative marking for NAT questions). So the calculation goes:
MCQ Marks: Total marks (1 mark) + Total marks (2 marks)
Total marks (1 mark) = 1 x no. of correct attempts – 1/3 x no. of wrong attempts
Total marks (2 marks) = 2 x number of correct attempts – 2/3 x number of wrong attempts
NAT Marks: Total marks (1 mark) + Total marks (2 marks)
Formula: Total marks = Total marks secured for correct response – Negative marks for wrong response.

There will be Multiple choice question (MCQs) where you will have four options and only one is correct. Then you have fill the blank type where you won't have any options you need to solve the question and put the obtained value in the blank and the final question type which is added this year is the Multiple selection questions (MSQs) where you will have four options and more than one can be correct you will need to choose the right option and in such questions if you do not select all the right options then you will be awarded zero marks.

How to clear GATE Exam in Computer science
Hello,
Hope you are doing good.
Below I have provided some tips for preparing for the GATE examination:
-
The most important thing that has to be done first is to understand the exam pattern, the dates and the syllabus . This helps you to understand which topics you will have to spend more time on and plan your timetable accordingly. Below I have shared a link where you can find the syllabus and the weightage: https://engineering.careers360.com/articles/gate-syllabus
-
Once you get to know about the syllabus and the dates, now you can set a timetable. You can decide how many days or hours you will be keeping for each subjects, revision and to practice previous year papers and mock tests. Manage time in a way that you spend enough time on difficult topics and also ensure that you have ample time for revision and practice.
-
Another important thing to keep in mind is to find the correct books for you . Some books may be hard to follow, so try to get materials that are written in a student friendly language. Below I have given a link where you can find details about the best study materials for the Computer Science branch:
https://engineering.careers360.com/articles/what-are-best-books-for-gate-cse
-
While studying the subjects make sure you keep note of important points and equations in a separate book . This will come in handy at the time of revision.
-
Once you are done studying the subjects start revising and doing previous year papers and mock question papers on a daily basis . This helps you to recollect the formulas, gives you an idea on where you have to improve and will also help you to manage time better. Make it a point to solve atleast one paper every day during the month you have kept apart for revision and practicing question papers.
Below I have shared a link where you can get the previous years question papers for various streams:
https://engineering.careers360.com/articles/gate-question-papers
- Another important thing is that don’t study anything new at the last minute and this can create confusions.
-
NEVER TAKE YOUR HEALTH FOR GRANTED . Get proper sleep, eat healthy food and keep your self hydrated. Ensure that you do not stress your self too much and give enough time to relax and take breaks. Always remember that if you are stressed out then take a break as it would not bring out any good results when you put yourself in more stress.
-
Finally, on the day of the exam relax and don’t get tensed. Keep your mind clear and give the exam. You will surely be able to do well.
Following these and being completely dedicated to this, I am sure you will be able to clear the GATE examination.
Hope this was useful.
Good Luck

Hi Aspirant,
Let me clear this to you.Bsc (3 year) student are not eligible for Gate .The eligibility for giving gate examination is that you must have pursued 4 years qualifying degree after 10+2 level.However Bsc degree holder in engineering,technology etc who have 4 years of study are eligible for Gate however.
Hope it helps!!
In the CS 2021 GATE syllabus, only the word integration is mentioned. So, do we just have to consider only Definite and Indefinite integrals or we should be studying on multiple integrals and gamma / beta integration too just like the ECE syllabus ?
Yes, you have to study the whole Integration as like ECE or EE or CH or CE or ME branches.
The word integration doesn't means that it will only come as indefinite or definite integration. You have to study all the sub topics, like single integration, double integration, triple integration, gamma or beta function, Euler's formula, wallis theorem, etc.
You can check out the cse previous years question papers for the detailed topic wise distribution.
Because in the syllabus it is not mentioned topics wise, but if you see the previous years question papers, then you would get all sorts of questions based on integration.
If i have cleared gate in 2021 then can i take admission for MTech in 2022?
A gate scorecard hs valid for 3 years so definitely if you crack gate in the year 2021 then you can take admission on the basis of your scorecard in the year 2022. However if you wish yo improve your score, then you can again appear for gate and then the that scorecard will be valid for the next 3 years.
