Dear student
At first congratulations and best wishes for your result . I can predict your All rank about 4-5 lakhs. 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 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 specially in MBBS and BDS and even in BAMS BPT BHMS too .However you can get easily many private medical colleges.
