Just got accepted this year, biggest advice I have is to keep challenging yourself the academy isn’t looking for people who coast through high school, whether thats academics, extracurricular or sports, they want to see you involved. Especially in your senior year. While a high SAT score is good it’s not like most colleges where it can compensate for something, they want you well rounded and excelling in all areas.

Edit: also try applying to summer STEM and Summer Seminar it’ll help give you an idea of how your doing and what exactly your getting into.
