If your SAT scores aren't so hot consider taking one of the SAT prep classes some companies offer, I have had friends who thought they helped, but I've never taken one myself. Opt to take more advanced (honors and AP) classes if they are available rather than coasting in the easy ones. Extracurriculars definitely count more here than most schools, get involved in stuff, whether it be an athletic team, a community service organization, or a church group, get involved with something. Demonstrated leadership ability on the athletic field or within some organization means a lot here. Definitely talk to your blue and gold officer, and prepare well for your interview for a nomination with your congressman, be ready to answer the question "Why do you want to come to the Naval Academy?" don't make a prepared statement, just give it a lot of thought so you can give a good answer. Start thinking about which teachers and members of the community you can get references from. A good reference letter will really help when the admissions board is trying to decide which of two very similar candidates to accept. The competition is steep here, and there is certainly a lot of emphasis placed on SATs, but not having a 1500 doesn't mean you don't have a chance. The academies do tend to take a more whole person approach than other schools, because they are looking to develop you as a whole person, not just academically.
