Hello student as this is the first year when admission in AIIMS is on the basis of marks/rank obtained in Neet so it's difficult to predict exact cut off.

If you're from General category it's little difficult for AIIMS as we all know that seats are very limited and admission is directly based on merit rank.

You can use careers360 college predictor to predict college on the basis of marks obtained in Neet.
