Dear Shweta, there is no such cut-off marks for AFMC. Let me explain step wise.
a.) Computer Based Test - 20 Marks
b.) Interview - 50 Marks
FINAL SCORE = NEET SCORE/4 + CBT Score + INTERVIEW SCORE
As you can see your NEET score will hardly matter at the step of getting called upon for Interview. It is divided by 4 to get added to final score.
So, even if your score is 10-20 marks less in NEET, make sure you score well in CBT and Interview which will compensate your NEET score.
Last year the cut off for boys and girls was 551.
All the best
Hope this helps
