Just my two cents here: either you are x3 more academically qualified than most USAFA candidates, or you have taken similar classes to them, and have simply been awarded college credits; i.e., your mastery of the course materials is very similar, your classes were just taught by college instructors. I believe the second case is more likely, as there is only so much knowledge and learning that can be acquired from birth to 18 years of age.
BUT, I'm an optimist. Let's say that you are extremely above-average academically, and do not need to repeat courses you have already taken at the Academy. I still believe you have a golden opportunity to go to the Academy, and set yourself up for an excellent Air Force career.
- Option 1: The Academy grants you credit for many of your college courses: Great! Use the extra time in you schedule to lighten your course load over the 4 years, or pick up a double-major. Either way, set yourself up to be a great candidate for grad school, if academia is your passion.
- Option 2: The Academy makes you repeat many of your college courses: Still a great opportunity! You've taken these courses before so you should do great in them. You will get excellent grades with minimal effort, all while really mastering important undergraduate concepts. Furthermore, use this advantage in time to place more effort into your leadership (40% of class rank), physical fitness (10% of class rank), clubs, sports, teams, etc. Graduate #1 in your class, go on to serve an excellent career... "distinguished," "distinguished," "distinguished..." When you talk to cadets as the Chief of Staff of the Air Force you can ascribe all your success to showing up to the Academy with 80 college credit hours.
I was kind of joking with the last part, but I hope I got the point across. No one is overqualified for the Academy. The institution is a humbling experience, and will be plenty challenging regardless of how prepared you are when you show up. It's easy to do one element of the cadet experience well, to excel at all elements takes talent, hard work, and sometimes a bit of luck.
