If i see previous year rankings then based on your rank in obc which is 554 . You are eligible for getting different nit except the top three nit.

You should be getting NIT Allahabad, NIT Bhopal, NIT Calicut, NIT Durgapur, NIT Jamshedpur and many more.

If you haven't got in first and second round then you will get in third round.

Thank you.
