Hello Avinash,
There is no chance to get any NIT or IIIT because you have not score 65% in 12th board, but you can try in a private college. I think you can get a good private engineering college.
All the best.

Colleges like National Institute Of Technology (NITs), Govt Funded Technical Institute (GFTIs) are participating colleges through JOSAA counselling which you will get.
But some of the private colleges also take admission on the basis of JEE Mains rank but not through JOSAA counselling.

Yes, you can get the college as your rank is good. Just check the college details in the link:
