I just wonder why he didn't get an LOA.
Very few LOA's are given. While your son sounds amazing, rest assured, so are several thousand others. Who are still waiting to hear from an SA.
I have a client whose son did not get in to USNA last year. My son did get in. His son had two more points on ACT than mine. He points that out to me at various social situations. Repeatedly. Gaining acceptance, via LOA or not, to any SA is a mysterious combination of character, leadership, recommendations, strength of high school, community service, athletic ability, interview, essays, as well as medical qualification. Plus another intangible, the needs of the Navy (Army, etc.)
A super qualified kiddo who gets scholarship offers from outstanding schools may not get in to USNA or another SA. My oldest is in vet school at Texas A&M. He received a President's Endowed Scholarship there in 05. The Honors Program at TAMU awarded over 1400 prestigious honors scholarships that year. USNA will have only approximately 1250 in the class of 2014. Compared to most of the "plan B" universities, the odds are quite different at a Service Academy.
Yes, at this point in the game, the pool of applicants to USNA is narrowed down to those who are 3-Q'd and have a nomination. I think if any of us could leaf through those packets, we would be AMAZED at the quality of the applicants.
Sound advice presented by the two previous posts. Pursue Plan B. Most who earn an appointment to a SA keep plan B paid up right through I-Day. We did last year.
