Hello, 

As per your requirement, i would say that as you want admission in mysore medical college, then you can apply for state quota counseling if you habe domicile or aiq counseling depending on your marks. Aiq has 15% reservation pf seats and state quota has 85% counseling seats.

Getting a seat in government medical college is depending on many factors like studenrs to seat ratio, cut off, reservation etc. 

The cut off as per your caste would also depend on which state domicile you have as few states havr higher cut off even for st caste. So it varies from state to state.

 As per your marks, you need to check the cut off according to your category, and predict your chances.

Good luck
