Hi !

You need to clear the particular subject in which you were failed , because it is mandatory to pass the MBBS course with a minimum percentage , which is different for reserved and non-reserved category. The general and OBC category candidates are required to score atleast 55% aggregate marks in MBBS , SC/ST candidates are required to score minimum 50% aggregate marks.

So , you need to pass the subject and score minimum percentage to be eligible for AIIMS PG.

All the best !
