Since you hail from a reserved category and belong to a state with many goverment medical colleges you have an edge and a pretty good chance for governement medical college.

Apart from that  450+ is Actually a pretty good mark for deemed or private medical colleges. you must use the predictor tool to understand where you stand.

All the best Rajkumar!
