Hey i'm in d amu..so i think u should atleast aim for 600 marks..last year it went to 551 but it's a hoax marks..so my advice to you to score atleast 600

Hello Masud

If by 'appropriate NEET score' you mean the marks required to get admission in AMU, then knowing the last rank who got admission in AIQ in AMU, will be able to give you a concrete idea of the same. 

There are 80 MBBS seats in AMU. In 2017, the last rank from unreserved category to get admission in AMU was 7,422 with a NEET score of 567 (out of 720).

I hope it helps.
All the best!
