You cannot get CSE in NSIT though you may get some other branch here. Good NITs like Surathkal, Trichy and Warangal have an even higher cutoff. Getting CSE in NIT Delhi also seems tough. If you have given the IP entrance exams, you can get CSE in one of their colleges depending upon your rank. Sorry to say but with these scores, getting CSE in a good NIT seems a bit out of reach.
