Keep on trooping!
That's really good that you've been able to try and sort through it all with another doctor who seems more amenable as well as accurate. DODMerb however will still be REALLY dismayed by this news- even if it was a misdiagnosis, even if you have ODD and not MDNOS, that's not a good thing that you needed it in the first place. I've got some ugly stuff in my file too, and although I would be eligible for class of 2017 I'm not banking on getting in to that class. I'm not a DODmerb authority at ALL but maybe what you can do to rehabilitate your application is to really find a way to show your improvement- rebellious, even if not chemical, isn't what they're looking for exactly (I know, it was in middle school and that's a ridiculously long time ago, but they're just trying to be safe). So I would possibly have my parents contact my MALO and say how you've changed and so forth, and this psych eval is a HUGE step in the right direction.
Simply because people are lining up at the door to get into the SAs and for the ROTC scholarship, I don't think that you're very likely to get in, but if you go to college immediately after graduating high school and keep your grades up and apply to transfer for the class of 2016, that says that you're very committed indeed and your performance at college away from your parents will say a lot too.
@kp2001: when you say disqualifying, do you mean disqualifying so that she would have to get a waiver, or disqualifying as in she would have to try and get a waiver but would probably not be able to get one? Also, do you have any tips to make sure your MALO doesn't think you're trying to hide this sort of thing? I assume it looks bad to act like the perfect candidate until the DODmerb itself, but I have no idea, because you don't want your MALO to write you off, either. As I'm in a similar boat, any advice would be appreciated.
