3 applied and 3 appointed
From my DS's high school, 3 students(2 male and 1 female) applied to USNA and they were from the same congressional district, and all 3 were appointed. It is a small high school, but all 3 were considered great fit to USNA. This was for the class of 2016. My DS had an LOA, so he might have not used MOC's slot, but I don't know. Anyways, I was scared when the Mother of the other male told me that he had a perfect score in SAT II Chem (USNA does not require SAT II, but he could send it) and I am sure he had a great score in Math as well, but my DS received an LOA and received an appointment 2 months before his classmates did. My DS and his classmate kept good relationship while applying and they are good friends and doing great at USNA. His best friend applied to USAFA and he got in, but it was a good thing to have friends applying to service academies to support each other during the long application process. You just do your best and if USNA thinks both are great fit, they will appoint both.
