Now I am definitely no AME or Flight Surgeon, but I can tell you that my civilian medical process is a joke compared to what the AF puts you through. On a scale of 1-10 my experiences were a 10 with the AF flight docs, and my FAA docs exam I would rate a 2 as far as thoroughness is concerned.
You're not in a high threat environment like the AF anymore, you really could just walk into a doc's office and get an answer on the spot about your chances.
