A close friend of mine entered USAFA, but broke his foot during BCT and was sent home. For that year, he attended Texas A&M, and then returned the following summer to USAFA. As I understand it, his courses either transfered or allowed him to test out of equivalent courses at USAFA. In the end, the extra courses allowed him to double major at USAFA. But yes, you will still be a freshman and attend the academy for 4 years. There are no exceptions to this policy as I understand it.
