As others have stated it varies det by det. regarding times, but the consistent issues are you will have 4 things. Academics, LLAB and PT.
At our DS's unit it is 2 days a week he has something AFROTC. When he was a freshman, if you maxed the PT you did not have to go to the mandated PT at O'dark thirty, they trusted you to work out on your own. However, the following semester you typically became a flight PT instructor, which meant you were there at O'dark, 30 mins. prior.
They will give you everything, but your socks, shoes and sneakers, just like the guys. They will not charge you a penny for any of the items until you commission, and even than at is your choice to take what you have or the allowance to buy all new. DS is taking the allowance, but that is because he is going UPT.
I too am sorry you got the TWE. If you plan to re-apply for the AFA next yr., tell the det CC now or the 1st week at school. They will be able to give you an ROTC nom., but nothing will tick them off more than if you blindside and say "OBTW, can you give me an ROTC nom, it's due next week"
They want their cadets to attend the AFA if that is what their cadet wants. It will not upset or offend them, they will not see it as being disloyal to AFROTC. They will see it as maturity.
I would also suggest that if it is not too late to do the May or June SAT/ACT do it! This will help you in several ways.
1. AFA next yr., because finishing your SR yr in HS you should score higher than what you did the fall of your SR yr...thus, raising part of your PAR.
2. AFROTC does best sitting, not superscore. AFROTC will use these scores for:
~~~ IS Scholarship
~~~ FT as a 200.
I know you want the AFA, but you always have to keep planning at the same time for Plan B.
Statistically, the amount of TWE's that re-apply are low because once the cadet is at college, makes friends, in ROTC, sees the 300/400 cadets get their dream AFSC, and than have to add on the MOC essays, interviews, etc as a college student they change their mind. Thus, that is why taking the SAT/ACT now can help you a lot later on.
I am not saying you won't re-apply, I am just saying be prepared so you have a lot of options.
I would also advise that you work out all summer long for that PFT. It will really be the 1st time you can shine in a positive or negative manner. The AFROTC cadets will run PT and you don't want them to learn your name the 1st week because they are shouting at you to do the correct form for a sit up or butterfly kick. You don't want them to be behind you in the run telling you to pick up the pace.
Workout in every weather condition, including rain. They set the date for the PFT and if it is 90 degrees and 100% humidity at 6 a.m. they will still hold it, just like if it is raining and 40 degrees.
Good luck...Above All...Aim High
OBTW, many AFROTC dets have something called GMC nights. It is social just for 100 and 200's. It is a great way to bond with other cadets, especially if you are attending a very large university.
