Hi Rishika 

As you secured 8275 rank in sc category ,you have chances of getting admission in AIIMS ,if we consider last year's cutoff rank and estimate if you'll get a medical seat in AIIMS .

The last year's cutoff for sc category in AIIMS(in those you a chance) were as following-

1)AIIMS Bhopal-8657

2)AIIMS Patna- 14195

3)AIIMS Rishikesh-10471

4)AIIMS Raipur-13607

5)AIIMS Bhubaneshwar-9038

6)AIIMS Nagpur-13638

7) AIIMS  Guntur -14510

In above mentioned AIIMS there  are higher chances of getting a medical seat .

I hope this information is helpful to you.

All The Best
