Did I look at the practice test on page 272-277 to study for today's test?

No, I did not look at the practice test on pages 272-277 because I understand it, I've done it already, and it's all just another review for me. I also didn't look at it because all of Tuesday night I was sick, and yesterday night I was working on homework for other classes. Since it's all a review for me, I skimmed over Unit 2 briefly, but the practice test was all one big review that I've gone over quite a few times in class.
