Dear Candidate

See as per your Marks 546 it is not difficult to get a Government Medical Seat even if you have a state quota and another quota if applicable. 

You cannot get into any medical college with this mark.

At this stage, I will suggest you must use this link to get a fair idea about the colleges both Private and Government you can get as per the score you have received and then plan accordingly.
