Sorry to say but even if you belong to obc caobc category to get admission in NITs under CSE branch you need to score a rank below 20k. As the cse is among the core branches of engineering hence it's cutoffs are also very high. But you can easily get admission in top private colleges affiliated to jee mains and that too in cse branch.

You can predict what colleges you might get with this rank by going through the link of college predictor tool given below.
