Hii Rajat,
Your score is a bit good.As per the previous years cutoffs you have a little chance of getting admission to the medium ranked NITs such as NIT Nagpur, NIT Surat, NIT Jaipur,etc and you can get lower ranked NITs such as NIT Durgapur,NIT Andhra Pradesh, NIT Hamirpur,etc.You can also check for Colleges on careers360 Gate College Predictor.
