I applied to NASS the first day the application opened last year and was rejected within a few weeks. Last month I accepted my offer of appointment to the Naval Academy class of 2022. Don't freak out over it! A ton of people don't get into NASS, like me, but still get into the Academy. Also, a ton of people who do get into NASS don't get into the Academy. So don't stress, it's a good experience but not the end of the world. In the c/o 2022 group chat a lot of people are saying if you get into the school you don't want to talk about NASS during plebe year because it'll make the detailers go harder on you.
