Was Sky expecting to regret coming to Arithmancy this time? Fully. But she didn't have anything else to do, considering she had decided to take a break from studying for her NEWTs this week. So here she was, skiding into class on her knees like she was going under a particularly low limbo bar in order to avoid having to squeeze past Professor French's rather large belly which was blocking the doorway. One would think that he'd realize that people were having trouble getting through.

Anyway, she walked up to the board, wrote the stuff down then found herself a desk close to the door. Just in case she had to make another quick getaway.
