Well Pratik first of all well done. You got a average rank in NIMCET I.e. 2275 in general category and 749 in category . But you haven't mentioned which category is it.

So I will consider it to be OBC category. Now if I consider previous year closing rank of different nit's then I find that with this rank in obc category you will get a seat in nit except the top ones which is Trichy Warangal Surathkal etc.

So you will get in the average one nit.

All the best

Thank you
