Hello, 

As you have mentioned that your neet score is 121 marks and you fall under SC category. Firstly 121 marks to get mbbs is too low. So, there are no chances to get a seat for mbbs. Seondly, for BHMS if we talk abiut about cutoff its cutoff is about 480+ for General category and 420+ for other Categories.

And if we look over previous year's cutoff for bhms for private and government colleges it was about 320+ and 400+ for Private and government colleges respectively.

So, with 121 marks you can neither get a seat under 85% home state quota nor under 15% AIQ.
