So you are going to enter at the very least an AS250? 100 is freshmen, 200 is sophomore that was a 100, 250 is sophomore with no ROTC until sophomore year.
I would research the threads here regarding 100/200/250. The more you are informed the better you will feel entering.
~ IE you are a Sophomore, never in AFROTC. That would make you a 250.
Are you a tech major? Do you want to go rated? If rated are you going to get some flight hours in?
The more you research through the old threads, the more you will appear more prepared when they ask do you have any questions?
~ IE last year for SFT it was @90% rate, the avg cgpa for non-tech was 3.3/3.4 and 3.0/3.1 for tech. What was your avg cgpa? What was your selection rate?
~ Of those not selected how many became a 500? 500 is someone that was not picked up for SFT, but retained and will compete again. Basically a junior...still not contracted since they did not attend SFT.
I cannot stress enough how important getting an SFT slot means for AFROTC regarding commissioning. Granted you need to pose the questions in a non-antagonistic way, but you still need these answers.
~ I would pose it as something akin to I am not looking for a scholarship, but I want ADAF. If not selected for SFT, how does it work if I am disenrolled? Can I still go OCS?
