Hello, 

As per your requirement, i would say that as mentioned above, being an hindu does not matter as there are jo such reser6 for it. Being from sc it really matters as you have specific reserved seats for it and cut off would be lower basically than general candidate.

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

As cmc is renowned collegr so getting admission would br tougher if you don't have 450+ markd as competition are higher for cmc. 

Apply for its counseling and see your chances.

Good luck
