Hi Tanmay.

Unfortunately a score like 256 is not upto the mark for securing a private  BAMS seat. Since you have not mentioned your category , I assume that you belong to General category. And that makes it even more difficult for you. In the all India Quota a candidate needs 480-490 score to secure a government seat. When it comes to private colleges the cutoff is lower but still it is lower than 340 . However the cutoff may vary and since this course has been added to neet only recently it is difficult to find the exact cutoff score.

Hope this helps.

Good luck!!
