Hello aspirant
Hope you are doing well
It is difficult to predict the cut off marks or ranks beacuse  it may vary every year depending on the following factors
1. Level of question paper
2. Total no of candidates
3. Category of candidate
4. Total no of seats
5. Marks obtained by students
Here is the link for the rank predictor

As you have not mentioned your category so assuming that you belong to general category.
So previous year cut off marks for AIIMS were as follows for gen category
1. AIIMS Delhi - 705 marks
2. AIIMS Bhopal - 681
3. AIIMS Bhubaneswar- 681
4. AIIMS Raipur- 670
5. AIIMS Rishikesh -675
6. AIIMS Jodhpur - 680
7. AIIMS Nagpur - 660
So your score must be above than 650 to get admission in AIIMS
Good luck
Hope it helps
