Candidates are required to have a score of at least 450 to 500 to get accepted into a decent medical college. With your marks and rank it’s very difficult to get admission in any government or private medical college. In this situation I would suggest that you either opt for non-medical streams or, if you want to get admission at Government Dharmapuri Medical College, thoroughly prepare for NEET again and appear for the exam in the upcoming year. Please remember that you must score at least 550 if you want to get enrolled in a good medical college.
