The candidate should have passed 10+2 or equivalent examination with an aggregate of at least 75% marks. For SC/ ST and PwD candidates, there is a relaxation of 10% as they need the aggregate of minimum 65% marks.

By observing last two year cutoff for jee advance and seeing the paper difficulty level ,it is really difficult to tell you accurately about the cutoff.

Assuming that you are a general PWD STUDENT then your cut-off will be somewhat between 40 -45 marks with some slight error and if you belong OBC pwd student then it will lie between 35-40 marks and so on.
