Since the JEE Main results have been out a long time ago it would be way more helpful if you tell us your category rank and all india rank. Otherwise we cannot guide you with incomplete information.

Comment below your rank so that I can tell you about your possible colleges.

Hello Sahil, I would suggest you to, first of all, choose home state government engineering colleges like NIT Patna because in that case, you can easily avail home state quota and OBC category which would make it a little easier to secure a seat. Although I doubt that you would get a seat in NIT Patna and if you apply to other states then there's the least chance because of another state quota.
