hi,

see your 12th score is below average which makes it difficult to get admission in tier 1 institute. now the admission system and cutoff score varies for each colleges every year and depends on number of applicants for any particular course, seat intake etc. so it is difficult to say the chances of yours for that particular college. since this is a private university you may try for management quota also.

I suggest you to apply for more colleges as well to secure the chances of getting admission.
