U may want to speak with or ask to speak with the Recruiter's Commander. I served for will be 20 years in Active Duty and Reserve Air Force, (will retire in June). The Air Force program is excellent and you will have great opportunities to advance and become a very experienced nurse quickly.
I wouldn't let it bother me about the questions from the others, once you start your AF program U will become an exceptional nurse, most likely by passing "the others" skills.
I guess the process is sometimes lengthy, but it will be worth the wait. Once U get in, and work for a year, look into being a Flight Nurse, I did that and I loved it.
Good Luck.
