I wish I had gotten my studying done earlier in the day. Not that I don't like it, it's just that now I'm rushing it and I'm tired and probably not going to remember a huge chunk of what I'm writing down.
...actually, I'm probably not. I can answer all the review questions for chapter two without the book either because I took really good notes in class, or because I already know these things (it's mostly the latter). Even then, I'll have more than enough time in the morning to review my notes and eat tacos with my friend. Again, I take so many notes, I practically don't need a book (and it's a really good thing because I don't really have a physical copy).
