Well, yesterday is yesterday, and today I'm studying for the midterm. I'm looking at this stuff and trying to put it all together in my head. It is the first test we've had in this class, and the first test I've had from this particular teacher, so there are a lot of unknowns here.
Yesterday, I felt competent and smart. Today, however, I feel as if I set my smarts down someplace and promptly forgot where I put them.
