Hi Nunavath

As you mentioned ,that you have secured 51 rank in st category ; you have higher chances of getting a medical seat in AIIMS bhopal or bhubaneshwar even in new delhi ,if we consider last year's cutoff .

The last year's cutoff rank of AIIMS bhopal and bhubaneshwar for st category was as following-

1)AIIMS ,Bhopal-22120 rank

2)AIIMS Bhubaneshwar-19414 rank

I hope this information proves helpful to you.
