Hello aspirant , it is quite difficult to predict marks as marks versus rank scenario changes every year. This year there has been a great shift in marks and rank graph. Moreover it also depends on the category of the student. The other factors which influence admission is , state quota and AIQ quota. Through AIQ quota one need to score higher than what is needed with state quota. It also depends on your category

Assuming that you are from general category .For Mysore Medical College through AIQ rank within 1200 to 1300 could fetch you a seat .
