If your FFR didn't tell you (not sure if he can), you could try calling / asking the nominations coordinator for your MOC. But frankly, it's not something you can control. I know the waiting is hard, but you should be focusing on everything else you can control (grades, ACT/SAT scores, working on Plans B, C, D, enjoying your senior year). If you have submitted the strongest package you possibly can, there isn't much else you can do but wait.
I'm not sure about a more competitive district = more slots, but if USMA wants you (and you have a nomination), they will find a way to get you in.
