Hello.

It depends on your rank whether you can get into an NIT or not. The marks vs rank keeps varying each year due to various factors like difficulty level of the exams, average score of students etc. This year, the NTA will be considering the best of the two attempts, so the cutoffs might vary a bit. You could use the rank predictor to predict your rank:
