Merwyn: ask an undergrad- especially a UAA undergrad- if they spend 2-3 hours of study for each hour of class. When they get done laughing at you, perhaps you could ask a more realistic question, like, "Why would a motivated and driven student apply to a college that's "waiting for them," when they can knock out all their prerequisite courses now?"

Yes- I'm sure colleges are indeed "waiting for them," along with their parents' hard-earned tuition money.  "Freshman Comp." at UAA is the exact same class as "Freshman Comp" at Northwestern: the only difference is the $55,000 a year difference in price.
