There is a bit chance that you will get seat in the NIT Warangal in CSAB round. You can get some lower branches in NIT's like Raipur, Jamshedpur you can also get NIT Rourkela for dual degree program. Better if you participate in CSAB round. You can also use our college predictor to estimate the best college for yourself.

Good Luck!!!
