Hi

This is difficult to make prediction as  cutoff  depends upon various factors like :-
******* number of students/ candidates that appeared in the jee main exam,
******* number of available seats,
******* performance of different students in the examination,
******* the branch you want,
******* the category you belong etc.

But
What is your percentile / rank?

Admission is on the basis of rank.

Anyway,
You can know the colleges in which you have chances with the help of our college predictor for which link is given below:-
