Hello Sharanya,

First of all congratulations for such a good rank in NEET.

As you are from Delhi you should definitly go for Delhi state qouta instead of All India Quota as it'll bring you a step closer to chances of getting seat in Maulana Azad Medical Colege.

Going by the last year data of 1st round seat allotment, for general category

• AIQ- 22AIR
  
• DU INTERNAL- 1170ai8r

these are the last rank (general category) to get admission in this college.

Hence you should go for MAMC from DU as your first choice to secure youself a seat. 

Talking about the fees structure, their is no as such a difference in the fees for students getting admitted through AIQ and through DU qouta.

I hope this helps.

All the best for the future!!
