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.
