The qualifying marks for GATE vary every year and depend on factors such as the difficulty level of the exam and the performance of candidates. Separate qualifying marks are declared for different categories such as General, OBC-NCL/EWS, and SC/ST/PwD. Typically, the qualifying marks for OBC-NCL/EWS are 90% of the General category cut-off, while SC/ST/PwD candidates have 2/3 of the General category cut-off.
