Dear Aspirant

At first congratulations and best wishes for your result  . I am afraid to say with this marks your chances to get government colleges are almost negative through All India counselling for 15% seats  despite of SC category. You must score atleast 470 to get government colleges by AIQ through SC category. You can still try in state counselling  for remaining 85% seats . Different state counselling cut offs vary from each other.
For different states it depend upon availability of colleges, student number etc various things . You have not mentioned your state . You must mention that for us to answer precisely. You must go for your respective state's counselling. Though chances for you are tough for you in there also for government colleges. However you can get easily many private medical colleges.
