Hi Vanamala 

For getting admission in BAMS 470 and above is considered the good score,But since you belong to SC category you have really scored good. You have fair chances of getting admission in BAMS. 

According to me you should try for BHU, NIA college. Then you should apply for state colleges if you have any state domicile. You will surely get admission in state qouta .

Hope this helps you.

All The Best for your bright future.
