Hello,

You cannot get NIT, ROURKELA with this much rank. Your rank are too high in sc category,  as per previous year reports sc category cutoffs are close around 8k for the lower most branch in spot round selection and if you have CRL 1.6lakh then you have no chances of getting into any NIT.  Try other college or take a year drop and prepare well and good. You can also apply for state counseling,  but chances for govt seat are much less.

All the best
