Hi dear,

National Testing Agency (NTA) has releases the NEET cut off percentile every year on the basis of following factors:

• Number of candidates appeared for exam
• The difficulty level of the NEET question paper 2020 in exam
• Total seats available

The cut off score varies every year and hence it is very difficult  to predict NEET score at which you can get AIIMS. However, with rising cut off every year and previous trend a score above 680 can help you in getting into AIIMs.
