Tests are the only things keeping my grades up. I'm the opposite of most people in that aspect. I vote all of school (college and uni are this way already) become totally test-based. Screw "homework". :D

I don't ever remember failing a test ever. Once, I got a C- on a science test-thing, but that was because of the idiotic excuse for a teacher. Of course, the next highest grade in the class was about a 20%.
