Quizzes!

I've taken a few quizzes in my pre-calculus class, and in most of them I do well, but the last one really caught me by surprise. I got a 35/50, it's not bad, but it isn't good. The quiz if I remember correctly was graphing equations, but we had to find the asymtotes and such, and I made an error and that basically ruined the whole exercise. But hey at least my teacher was nice enough to notice that even though I got one part wrong, I did the exercise how I was supposed to with the results that I got.
