Hello,
I am currently at the end of my sophomore year and have a 3.45 gpa. Hopefully due to the AP classes I plan to take it will go up to around the standard 3.7. I have always tested very well on standardized test such as the PSAT and PSSA. I have been going over practice tests and my projected score is about a 1400.
I know extra curricular activities help so I figure I’ll say what I do below… I am active in my community and will have over 200 hours of community service by the end of the summer, as a secretary in a club called Avedium(branch of S. A. D. D. Aka students against distructive decisions), as a member of my town “strong” program which helps provide drug free places and events for kids, chorus, select choir, band(clarinet, saxophone,and guitar), musical, church, youth group, cheerleading, swimming, throwing for track and field, and my school ambassador program.
I often run and work out on my own and when practicing the cfa I score about the average scores listed except for the spiriting exercise. Granted, I do have time to work on it more.
I do realize that going to this school requires a nomination. I am looking into internships with congressmen and any additional advice for securing a nomination would be great:).
Overall I just really believe in the school and would love to go there. I truly want to give the application process my best shot. If anyone can write down any suggestions below that would be very much appreciated. 
If it helps at all I am also a female.
USMA focuses more on class rank than GPA. Top 10% is where you want to be. You need to be athletically strong - varsity letter level, preferably in team sports. Average performance on the CFA won’t help your application. Try to max as many events as possible. Not sure what “spiriting” is? Focus on obtaining leadership positions, not just being a member of clubs, etc.
Head over to service academy forums and start reading up on the process. Good luck!
I really think your best shot is to be a recruited athlete. Pick a sport and get good at it, and if it is running, figure out how to get noticed. If so, it is possible to be selected for the prep school for a year if they do not think your grades are high enough. I know several who have taken that route and really enjoyed it because they have an extra year before all the competition begins, and they can see if they really want a military life.
@twoinanddone that is kind of a terrible advice. Sports recruitment is extremely difficult, especially at a D1 level. You don’t just pick a sport and get good enough in 1 year to get recruited.
