Hey,
It's always cool to see kids preparing for the Air Force early on, like I did. The Academy really wants well-rounded individuals. It will really help your chances at getting in if you have a varsity letter from high school. But that's not all, you have to be staminatic and in very good shape. USAFA students are required to partake in athletic activities everyday. I suggest you run a few times a week. Do pull-ups, push-ups, sit-ups etc... Academically you should excel in math and science. This means taking honors classes when possible. Get involved with leadership activities at your highs school like student government. Join clubs like CAP (Civil Air Patrol) and Boyscouts. Also, you have to be nominated by your state senator or a congressman when you apply. Now is the time to work hard. I am a sophomore in high school and am assuring my acceptance at USAFA by doing the things I need to while I have time. Good luck, keep working hard, and I'll see you in the Air Force.
