Math lesson

Ahhh, finals week approacheth. Here's a snippet of today's conversation:

Kid A: Ms! I looked at my grade, and it's really low.
MC: Yes, it is. You and I have talked about that a lot.
Kid A: I don't think I'll take the final. I can't pass unless I get 100%. See, because if your final is worth 15% of my grade, and I've got a 50 now, even a hundred would only raise me to a 57.5. So, should I take the final exam?
MC: Well, you certainly won't pass if you don't.
Kid A: Well, I don't think I'm going to take it.
MC: Suit yourself. But that was mad math skillz you just showed there, bud.
Kid A: Yeah, I got a C in math!

You can tell it's approaching the end of the semester when I am thrilled that a kid who redefines the term "underachiever" at least demonstrates some math ability.
