How good is your grammar?

At work I spend a good chunk of my day making sure things are spelled good and that sentences work like iPod factory employees. That's why, when I come across something like this, I feel humbled. Well, not really since I got a 9/10, but you definitely feel like that apostraphe comes into question when you see that .edu in the URL. Being an Oregonian, it brings a twinge of happiness to see this professor's grammar test have so much personality...something that would go a long way with corporate grammar skills tests.
