DoDMERB only quals or DQs. It is the commissioning source that determines whether to waive or deny. My guess is you should start with HQ AFROTC at Maxwell. According to your post you were DQd, and than you were waived. The waiver was not from DoDMERB, but HQ AFROTC.
~ I think Steve is trying to determine if you are fighting against DoDMERB's DQ or AFROTC waiver. It would be a different path depending on which one you are trying to go for.
Why did they waive you and than come back and deny it? Did something in your medical status change? The thing you need to understand is to appeal the denial it could take many months for the final decision comes down.
Not trying to go off track, but unless things have changed they will not pay for your college until that waiver comes through and you contract. That means you will most likely have to pay everything out of pocket for the 1st semester if the appeal goes your way, but does not become official until after that 1st semester (6 months from now)
~ My 3 kids went to 3 different universities. All of them had a rule in place that if they did not pay their entire semester, or were not on a payment plan within 10 days of school starting they were dropped from their classes. I know other colleges that don't do that, but instead they "lock" the students account. Most colleges will have students sign up for the next semester's courses by late Oct./early Nov. Again, if there is an outstanding balance than they will not allow you to sign up for the next semester.
ROTC scholarship would be taken into account, and the Bursar's office will know if you are on scholarship via your det. regardless of when the school gets paid. I would contact your det. now and ask where you stand in this situation. Will they inform the Bursar that you are on scholarship or you are not on scholarship according to them. If the latter is the case be prepared to have a payment system set up for at least the 1st semester while you await the results.
Best of luck.
