GATE 2021 General Aptitude Syllabus
The syllabus for General Aptitude is same in all subjects of GATE 2021. There will be 10 questions asked in this section, out of which half will be of 1 mark each and the other half will be 2 marks each. Also, the section is divided into two categories – General Aptitude, Mathematics and Subject-Based. For syllabus GA syllabus check below.
Verbal Ability: English grammar, sentence completion, instructions, verbal analogies, word groups, critical reasoning, and verbal deduction.
Numerical Ability: Numerical computation, numerical estimation, numerical reasoning and data interpretation.
GATE CS 2021 Mock Tests
Your GATE 2021 preparation should be done rigorously through practicing mock tests. The tests will help you practice a wide variety of questions. It will also help you in practicing time management well.
GATE 2021 CS Exam Pattern

How to Prepare for GATE 2021 CS?
Your preparation should be smart enough to help you bag impressive marks. But there are a few things that you are supposed to do before you start your preparation. First, you must go through the exam pattern and the marking scheme of the exam. These are a must and that’s why we have discussed them already, before coming to the preparation of the exam. After you have gotten familiar with both of them, you must look through previous years’ question papers. After you have done these two things, you can start your preparation. For preparation tips, read below.
Start your preparation with one section at a time. This will help you in concentrating properly on a single section. It will also reduce the chances of losing any marks in any of the section. You can start from the General Aptitude section as it is the easiest. The section doesn’t require any significant effort on your part. You should have the basic verbal and numerical aptitude. You will have to work hard for Mathematics and Subject-based tests as they carry a lot of weightage and are comparatively hard. Try to complete the important topics and the topics with more weightage first.
Set your priority
Set your priority for topics that are extremely important and cannot be afforded to skip. Get over with these topics first. Then move on to the topics that are less important or have less weightage. Go through those topics once that you have knowledge about. This will save your time that you can spend in practicing more important topics.
During your preparation make it a habit of writing down notes. These notes should be made for every topic. The notes should be short and to the point so that through one glance you get the gist of it. Notes should include only vital points such as mathematical formulas or concept explanation in limited words.
Once the preparation time is up, you must start revising the entire syllabus. Start from the easy topics that you can complete revising together in a few days. Then move on to more lengthy topics that will take up a little more time to revise. Do refer to the notes that you made during preparation. They were made for the sole reason to practice and revise.
GATE 2021 CS Books for Preparation

What is Computer Science?
Computer Science is the study of processes that involves interaction with data and that can be represented as data in the form of a program. It involves the use of algorithms to store & communicate digital information. The field involves the study of theory of computation and the practice of designing software systems.
GATE 2021 Preparation FAQs
Q1. How do I prepare for GATE 2021 CS parallel to a job?
Ans. You can prepare for GATE 2021 even with a job. You will have to start your preparation early. Give at least 3 hours every day to GATE preparation and increase your preparation hours on the weekends. You can also take weekend coaching so that you remain disciplined throughout.
Q2. Should I join a coaching for GATE 2021 preparation?
Ans. You can join a coaching if you feel like you can’t study on your own or you have discipline issues. However, you can prepare well through self-study as well. You just have to prepare sincerely and put in a lot of hard work.
