I'm one of those smartasses who gets 90's in highschool without doing any work, only to find out he's screwed in University because of his crappy work ethic.
Haha, I am just like that. Right now I'm a sophomore(high school, that is). I barely do any real work or study at all but I'm pretty smart so I get good grades. Once I have hard classes, whether it's junior year next year or in college, I think I'll be able to really buckle down and work hard. It's just not necessary to do that now...
