To get admission into Armed Forces Medical College or AFMC Pune for the flagship MBBS course, you'll have to appear for NEET and get top ranks in it. The cut-off for AFMC through NEET in the past few years are as follows:

2021
Boys: 614/720
Girls: 627/720

2020
Boys: 618/720
Girls: 637/720

2019
Boys: 596
Girls: 610

As soon as you complete your MBBS, you'll have to serve in the army for a fixed number of years, failing which you'll have to pay bond money to AFMC.

Hope I have answered your question. All the best!
