CBSE

Hello,
Hope you are doing well. No, you are not allowed to get NITs with 152 marks and 64.8% in CBSE because you are from general category and your marks do not satisfy NITs cut-off offered for general category. You can try for some other colleges which accept JEE Mains paper 2 score and ranks.
NITs won't be possible for you.
All the best.

Please indicate your state of domicile.
