Hi, as you have secured a good rank in your JEE Mains exam and you belong to OBC category as well so you can easily get into mostly any NIT. But the problem is that in this rank you may get to face problem in branch selection. Since your rank is good but still it is lacking far in touch with top branches(CS, IT, ECE, ME, EE). But ya you can get any branches in these which includes Chemical, Metallurgical and Materials, Civil, Biotechnology, Plastic and Polymer etc.

So I only suggest you to get through normal NIT's as well where you will be free to choose any branch you want to have. For this you may also try Careers360 College Predictor tool where you can easily predict different colleges on behalf of your rank(link mentioned below;
