Dear Naveen, NTA is going to release the exact cut off marks for different courses on 5th June.

As per the previous year for BAMS-

GOVERNMENT COLLEGES 

• GEN - 420+ & OBC - 400+

SEMI-GOVERNTMENT COLLEGES

• GEN - 400+ & OBC - 360+

PRIVATE COLLEGES 

• GEN - 300+ & OBC - 280+

Since the exam was bit easy this year, so for safer side your score should be above 430 to fetch you with govt college.

All the best :)

Hope this helps :)
