Hi,

Yes, AIIMS MBBS eligibility criteria for minimum of 60% marks in class 12th still exist and is for this year too. However, apart from AIIMS, for admissions in other colleges and to be eligible for NEET you will have to score at least 50% if you belong to the general category. There is a relaxation of 5% and 10% for reserved categories.

Here is link that you can refer for details on NEET 2021: https://medicine.careers360.com/articles/neet-eligibility-criteria

I hope this helped you.
