So I go to the computer lab to check what my homework assignment is for my math class at Davis. And I see a bunch of PacifiQuest kids on the computers doing this quiz. I ask about it, find the link, and get hooked.
It's pretty clever, and it makes me laugh out loud when I figure out the answers some times :). I bet a math major put this together...
