It depends up on the faculty, infrastructure and campus.

Admission in IIT is not based on 12th percentage it only depends on your Advanced rank. Since i don't know how was this year's paper but still at 150/372 its very hard to get good branch in any IIT. Also i'm not sure but the 12th percentage issue may also arise as one must have above 75% in boards.
