Since the cutoff ranks are much higher, admission to the CSE branch at BIT Sindri is unlikely for someone with an OBC-NCL category score of 79.64 in the JEE Main exam. You might look into private institutions and engineering colleges in other states, or you might think about other branches with lower cutoffs. Based on JEE Main rank, admission is determined by JCECEB counseling.
