What is the gate syllabus for computer science in 2022

The results of the 2021 GATE exam were recently announced, and IITs and the Indian Institute of Science Bangalore immediately released the expected schedule for GATE 2022, making it easier for candidates to prepare for the exam.

As per the IIT Kharagpur's released information about GATE 2022 examination – 

  • The application form for GATE 2022 will be available in the first week of September 2021, with the deadline for submission in the fourth week of September 2021.
  • In the second week of September 2021, the application error window will open, and the deadline for late applications with a late fee will be in the first week of October 2021.
  • The exam will be held in the first and second weeks of February 2022, and the admit card will be given in the first week of January 2022. The answer keys will be issued in the third week of February 2022, the results in the third week of March 2022, and the GATE 2022 scorecard in the last week of March 2022.

It is critical for every GATE exam applicant to be aware of all of this information, as well as the GATE exam syllabus since no examination can be prepared without one. The GATE exam is held for engineering students in all fields, and there is a different syllabus for each discipline. Today, we will discuss the GATE syllabus for computer science.
