Hello Tanzeela.

See if u have scored low in the GATE exam then u should be going for state colleges and private institutions which accept the low score for pursuing ur higher studies in the field of ur interest. U haven't mentioned ur marks so I can't give u any information about the NITs.

I m providing u a link for ur help.
