Hello Shruthi,

Yes you have chances to get a BAMS seat with 320 marks for OBC category.

But chances to get a govt.seat is little doubtful .

Anyway you have good chances to get a BAMS seat in private colleges.

You can use our neet ug college predictor link to know in what all colleges you have chances of admission https://medicine.careers360.com/neet-college-predictor?icn=QnA&ici=qna_answer

Hope this helps.

All  the best!
