Hi rupnarayan,
Congratulation for such a great score.
You can even get admission into top nits but not with any of core branches.

List of nits you can take admission into are
1. Nit jaipur , metallurgical engineering
2. nit warangal (biotechnology)
3. Nit surat with integrated courses
4.nit roulkela
5 . Nit nagpur
6 nit bhopal.

These are some reputed nits where you have to compromise with your branch.

But you need a good branch too then you have to option for lower nits like all northeast nits.

Hope it helps !!!!
