Sorry to say but you didn't scored enough to get seat in NIT as the cut offs for NITs for any branch is very high as compared to other colleges If we have a look on previous year cut off in general you need to score below 50k to get into NITs and below 20k to get into top NITs with you desired branch however whether you qualifies main or not doesn't depend on your rank but on your marks if you have scored more than the cut off of your category than you'll be able to give jee advance but the cut offs for different categories aren't out yet so you need to wait for that.

good luck
