"It looks like most of you need to be cleaned off before you leave. The homework will be up on the board shortly but in the meantime, if you need help with cleaning charms I am happy to oblige. Also if anyone wishes to practice any of the spells covered in this lesson, you are more than welcome to make use of the duelling arena. If you haven't signed up for Duelling Club yet, please be sure to do so by tomorrow as I will be closing sign ups in order to begin scheduling duels. Class dismissed."
