Hey Kaushik.

First of all congratulations for ur rank in the GATE exam. See the rank u have got is pretty enough for u to get admissioned in the good colleges like IITs for pursuing ur higher studies in the field of ur interest. U are having a good option for almost all the colleges. Seeing the girls quota is not pretty much fair for ur marks and rank.

I m providing u a link of college predictor. Hope it helps u.
