Sorry to say that you cannot get seat in NITs or IIITs or gftis

The cutoffs are very high

Many of new nits get closed at 18 thousand OBC rank itself including most IIITs and gftis

So you have to try state colleges

And try private institutions like srm , vit , sharda , lpu etc

Many accept JEE main score

Plz do complete your question its really not enough to help you provide with the answer pertaining to the question being asked!
