I had an interview for my MOC a month ago, and in the application I listed my top choices in order: USMA, USNA, and USAFA. A few days ago, I got a LOA from USNA. Would it be too late to tell them I want to change my order? Or should I tell them I got a LOA from USNA (maybe that will help me get a nom?)? I would be thankful to get into any SA, so I would like to maximize my chances.
