Hello

A score in excess of 480 to 500 would be apprecialbe to get into a college , although it would be safe to score in excess of 520 out of 720 via the State quota and in excess of 550 via the All India quota since the rank cutoffs remain around 4000 to 4500 at the all india level to get admitted into IGMCH , Puducherry .

My advice to you would be to try to score in excess of 500 if you are wanting to avail the seats though 85% state quota and in excess of 550 to avail it using the 15% All INdia quota to get into IGMCH , Puducherry since you are availaing the OBC quota where the cutoffs could be slightly lesser than the UR category

Hope this helps , thank you
