Same situation for me last year. I sent two emails: One to Cadet Command and the other to the head of ROTC at my accepted school.
Have fun at MMI! Remember: It is what you make of it. Don't do what I did and stay stressed out and locked in your room studying until you get your appointment...
I had the same issue, but it's because I had already done EQIP before for a low level clearance job and I forgot my username. If you contacted Ms. Drouin, she'll get back quickly with a solution I'm sure!
Sponsored Civil Prep here:
Nearly all of us at MMI received our appointments on the 25th. We're in contact with the other civil prep schools as well and the same goes for them.
Being overqualified for USMAPS means Civil Prep might be better for you if you don't get in. The way the email is phrased though, you should be cautiously optimistic. That sort of question is something you normally would be asking for later when it's getting close to the final cut.
