My advice is to don't get tunnel vision. IMPO you are what 14? Do not get me wrong, it is great to have goals, but just don't target or live your life with only that 1 goal to go to USAFA. Here is why.
~ Attending USAFA is not really just 4 yrs of your life, it actually will be 9 since you will owe at least 5 before you can leave that life, or basically I just FFWD you 13 yrs. to when you are 27. Take a minute and ingest that fact...27. If you want to be a pilot you will be @33-34 or 20 yrs from now.
If you want honest advice here it is:
1. Live life like you would be applying to an Ivy League like, Harvard, Yale, MIT, etc.
~ IOWS, hardest courses, athletics, leadership and volunteering on your resume
2. Get your medical records in order.
~ They go back until you are 13. If you have allergies, it can be an issue. Asthma is an issue. Vision is an issue.
~~ Again why you should not get tunnel vision regarding USAFA
3. Get involved in a sport if you are not in one already.
~ It is not just about the resume, but you will have to take the CFA and if appointed you will do BCT.
4. Stay involved in the Scouts … if you enjoy it.
~ It looks good on the resume even if you won't be an Eagle by that time. The reason why is because it shows long term dedication not only to the USAFA board, but the 1st hurdle...your MOCs (nomination sources).
5. Take the SAT and ACT as often as you can afford, starting even now. They superscore.
~ Make sure you take the PSAT as a junior. If you rank in the top 95% you will become a National Merit Semi-Finalist, which can be noted on your application.
6. If becoming a pilot is your dream, than ask your family to gift you for your Bday, or holidays some flight hrs. It will either cement the desire or maybe make you take a turn to a new desire.
Hope that helps you and other lurkers.
