You can get admission to pursue forensic science. However, before that, I would advise you to first completely focus on your scorecard. You should be on top as far as class 12th is concerned. However, there are various institutions providing graduation and PG into the field of forensic science like BT Institute of Excellence, Sagar or Gujarat University of Forensic Science.
