If not accepted...
Remember guys, the Summer Seminars are just used as tools for recruitment by the academies. I know for sure that acceptances to the USNASS is based on where an applicant resides, not by their merits. They will most likely accept an applicant from California as opposed to an applicant from New York. The year I applied for the USNASS (2010), barely anyone from the East Coast got in. It wasn't an attack on their application, they just had easier means of travel to USNA as opposed to someone from the West Coast. I applied for the USMA and the USNA SS's. I was not accepted to either of them. It was definitely a bummer, but a year later, I hold appointments from both West Point and the Naval Academy in my hands. I know another person who made it in to the USNASS, but did not receive an appointment to the USNA. A word to the wise (though I'm sure you know this): get your actual academy applications done as early as possible!
Good luck and I wish you all the best in pursuing a career in the United States Military!
