Have you gone onto the USAFA website and reviewed the graduation requirements? You’d see that all cadets graduate with a B.S. degree — heavy on STEM requirements — but it could be in a humanities field such as English, history or philosophy. The Air Force is a highly technical branch of the military. If you’re not into STEM subjects, you’ll likely struggle at USAFA.
Get online and read every tab, link, pulldown and page. Familiarize yourself with the academic, military and physical curriculum, as well as the entry requirements and service obligation afterwards. Rely on your own primary research and come to your own conclusions. SAs are not typically colleges, and they require careful research of the facts.
