For a Gen and OBC candidate you need atleast 550+ or 600 marks to get a govt medical college. Prepare for it by heart and good luck. Few other exams which you can look upto are AIIMS JIPMER and state PMTs.

Your score is good enough. But this score not work to get admission in Mbbs directly. You have to undergone an entrance exam before this that is Neet. Neet exam is conducting by NTA.
