Any advice for a sophomore in high school that is trying to receive appointment? Also did you have anything specifically on your applications that really helped you stand out? I am in AFJROTC and CAP and have good grades (they're going up dramatically too). I am willing to do whatever I can to stand out. In multiple clubs (trying to get leadership positions within), getting a job over the summer, competing in 2 school sports this year (3 next two years though), and will be doing a load of community service over the summer along with leadership seminars through JROTC. Any way I can stand out more or improve resume to increase my chances? Everything is appreciated, thanks for your time.
You sound like you're on the right track. Everyone has a few things that makes them stand out, so mine won't be the same as yours. Keep your grades up, stay involved, try to get some leadership slots and, above all, stay out of trouble.
Best advice I can give you is to apply fully and early. DO THE WHOLE APPLICATION and doing it before the deadline never hurt anyone. Be sure you know what is required way ahead of time and make a checklist for yourself with deadlines (Microsoft Excel can do wonders). Be sure you say everything that makes you competitive. I think my "resume" was 2 pages long, probably with some USAFA didn't care about; but I put it just in case they did care!
Also, break the application up into parts. I took Sundays as my "review" day and would see what items I needed to work on, what items I had already submitted (and I called to verify those items had been received a day or two later), etc. If you're not sure about something in the application process, just ask! Better to know for sure than guess and be wrong.
