Here's a list we can make about things which you didn't expect at USAFA. This might make expectations more realistic for incoming cadets and their parents. I'll start. * Just like at civilian colleges, cadets pay for their books, every semester. Be prepared to spend big money if you are unable to find used/loaners. Budget for it. *Since it's winter, you might wonder: Are there snow days at USAFA? Sure, there are a few, but before you leap for joy, know this: if you have a snow day on say, Thursday, know that the make-up day will be (wait for it) Saturday. No built in snow days. *Just because your friend's squad allows cell phones for 4-degrees, doesn't mean YOURS will do the same.
