Hello Anamta

As long you pass the subject in which you got compartment you are eligible for NEET and also for AIIMS. The only criteria for giving NEET is that you have atleast 50% marks in class 12th for general  and atleast 40% for SC / ST students. So, if you pass your compartment exam and got atleast 50% in class 12th exams, you are eligible for NEET 2021. By applying for NEET you can get admission in AIIMS as there is only one exam from 2020 for taking admission in UG courses in medical stream.

Hope this helps and all the best for future.
