"AFROTC pays for your schooling, so I'm not entirely sure why you'd need to take a bunch of CLEP exams to transfer in - I'm not sure they'd let you do only 3 years anyway, so you'd still need to be a full-time student for all 4 of those years."
Not quite. AFROTC does have 3-year scholarships available. For the most part, they're awarded to cadets who are in the program on a non-scholarship basis.
Also, if a cadet has not completed the entire first 2 years of AFROTC, he/she can still become an upperclassman by going to a longer summer field training camp. So having advanced standing can allow the cadet to graduate sooner and, thus, be commissioned sooner. This is true even if he/she enters on a 4-year scholarship but, through advance standing, finishes earlier. Cadets do have to complete the entire 2-year upper class program, but not necessarily the 2-year lower class program.
