I can't be serious

So, at the beginning of last semester, I said that I was going to be a serious student. Apparently, I can't actually be fully serious. To show you what I mean, here's what my notes from last semester's biology class look like:

I somehow managed to pull a B in that class. And here's the notes I've taken so far from this semester's human biology class:

I'm getting an A in this class--though we've only had one quiz, one homework, and one test so far (and one extra-credit assignment, which actually puts me at 102% in the class to this point--I think). So yeah, the grade is the important thing, not the notes, right?
