Hey aspirant.

See the score u have got is on the verge of the cut off score of the CIVIL stream in GATE exam. Talking about the NITs , u won't be able to brag a seat in any of the college for pursuing ur higher studies in the field of ur interest. About OSMANIA u can expect to get a seat over there under ur category criteria. U should be opting DTU for ur MTECH career as it requires very low score to get admissioned in CIVIL branch.

I m providing u a link which may get help u in some ways.
