Dear candidate....... hope you're doing good..

Well, basing upon your percentile in Jee Mains, you have the chance for getting admission into NIT Calicut. And since you're a OBC candidate, the chances of getting admission are high. You must produce your OBC certificate and other credentials at the time of counseling for getting admission into your desired college. Basing upon your rank, you may also apply for other NITs at the time of counseling.

Hope this helps you out........

All the best:)
