I had a few friends get done in 4, one of my friends in 3 because he took enough AP's in high school to start as a sophomore.

Me? I am graduating in May, after 5 1/2 years. I'd have been done in 4 had I not fucked around/taken a semester off/been able to get into every class I needed every semester. Applying to grad school for fall, though, TWO YEARS OR BUST.
