Hi Pradeep.

The eligibility criteria for BAMS course includes:

The candidate must have passed intermediate or  10+2 equivalent examination with English,Physics, Chemistry and biology .

The candidate should have scored minimum 50% marks in the intermediate/10+2 equivalent exam.

The candidate must have been qualified for neet UG exam.

Since you fail the second criteria you are not eligible for BAMS admission.

Hope this helps.

Good luck!
