GATE 2021 Syllabus for CSE (Computer Science & Information Technology)

Every year, GATE Syllabus remains almost similar to the previous same, merely there is a rare chance that GATE Syllabus gets changed.

Students who would be writing the GATE exam must refer the GATE CS and IT syllabus defined by IIT Bombay to start with GATE Preparation as the questions are formulated as per the official GATE syllabus.

Understanding GATE syllabus prior starting GATE preparation will help the candidates effectively plan the preparation strategy and score better marks. GATE CS and IT exam paper consist of questions from aptitude and the core subjects (CS and IT).

GATE Qualifying Cut off Marks for Computer Science (CSE & IT)

GATE Qualifying Cut Off is the minimum marks that the candidates have to score in order to qualify GATE examination. GATE qualifying cutoff is released by the conducting institute i.e. IIT Bombay for GATE 2021 exam along with the declaration of GATE results.

Till the time of GATE 2021 cutoff, students can find the GATE previous year cutoff and prepare for GATE exam.

Note: Bookmark this page so that you can track the topic that you have already covered or need to cover while preparing for the GATE exam. Sometimes going through this GATE CSE syllabus can remind you of the topic that you need to focus on.

However, there is no marks weightage to any particular section in the GATE 2021 CSE Syllabus, so all the sections of the syllabus are important.
