How to prepare for GATE Computer Science and Information Technology 2020

To Prepare GATE Computer Science and Information Technology Paper for 2020 you need to follow below-given steps.

Step 1 : Know the Syllabus

The first step the students need to take is to collect the correct syllabus. This step will ensure that they prepare only those subjects from which the questions are asked in the GATE exam. The same will prevent unnecessary time wastage by studying non-important topics.

Step 2 : Select the Best Reference Books for GATE Computer Science and Information Technology

The second step that must be followed by the students is to start studying those basic books of Computer Science and Information Technology that covers basic topics. It is necessary to clear the basic concepts first, which will aid in understanding the advanced studies.

GATE Computer Science and Information Technology Books

You can find lots of books with different publications in the online or offline stores, but I am going to share with you some best books which are recommended by the experts and universities for conceptual study.

Step 3: Identify Which Topics should study at First

You must always prepare yourself along with the syllabus provided. You cannot prepare yourself without the syllabus. After knowing the syllabus make sure that you cover all the topics relating to it and nothing is omitted. This will be very important to appear for GATE exam and win the exam. For more details, you can visit

Step 4 : Prepare a Study Plan

While preparing you must cross check yourself often with the syllabus you noted down. This will help you to work your schedule along with the syllabus and full focus on it. Then to know the timing you will require to answer each question, you can download the past question papers and solve the questions by yourself. Once you do this process, you will be able to recognize the timing required and correct it by yourself before appearing for the main exam. Timing plays an important role in the exam. So do keep all these things while your preparation and prepare at your best for the exam.

How to Prepare for GATE Exam 2020

  • Take a print out of the syllabus. See the weightage of different subjects.
  • Whatever subjects that are common to your current semester and GATE, or some tough subjects you have already done in previous semesters, start doing them. Read standard books referred for them. Don’t learn. Build your concepts.
  • Make your notes along side.
  • Make small targets, daily targets, weekly targets. At this stage, 3-4 hours of study would be okay. Actually, I’m defining the amount because people tend to ask ‘how time to study etc’. But actually, one shouldn’t keep time as the reference, but a topic or two as a measure of time to sit in day.
  • Keep targets of 2 or 3 subjects in a semester. Conquer them.
  • Practice previous year questions religiously.
  • Don’t just do a subject and leave. Revise it after 7-15 days so that you don’t forget it.
  • Mark the questions you feel are important, tough or conceptual.
  • Be your own critic. Take your own tests. No one can help you better than you, yourself.
  • Take a break of a day or two if you feel things are getting hectic.
  • Buy some previous year Question Bank, made easy or Ace. But do not follow them blindly. Look for better solutions to some typical questions on the internet.
  • Google good sites for GATE in Biotechnology, join some facebook group.
  • Have faith in yourself. Tell your parents about your aim and ask them to motivate you daily. The most difficult task would be to keep up your motivation high since the time is long.
  •   Don’t ever think about the results. Keep doing your share of efforts.

Last Step to Complete the Preparation

Lastly, the students must use solved and mock test papers as much as possible. This will help them immensely to clear the exam.

GATE Computer Science and Information Technology Exam Helpful Online Community & Forums

Online community and forums are helpful when you are newbie to the exam. Learn the tips & tricks from experts in these forums and communities. You can visit these reputed forums for GATE Computer Science and Information Technology exam related doubts and questions.

After completing B tech or B.E, most of the students who want to make their career in research and development, they look forward for masters. Getting a master’s degree from reputed universities like IIT, IISC etc. increases the importance and knowledge of his field.

When anyone qualifies GATE ,it means he/she has good engineering knowledge. That’s why R&D companies and organizations demand for GATE qualified score.
