What is the minimum rank I should get in AIPMT for admission in AFMC, Pune?

First of all, AFMC does not consider AIPMT ranks anymore for admission. The NEET 2023 is the sole criterion that is given consideration for the MBBS program offered by AFMC Pune. Only the candidates meeting the qualifying NEET 2023 Cut-off are eligible to participate in the counseling process. After every round of NEET counseling, the last rank at which admission is possible is released based on the seat allotment result. 

AFMC has yet to release the NEET 2023 Cutoff so you can refer to the previous year's cutoffs

Hope this helps you!
