Kari set up the room with dummies all over the room. She had this set up so they could practice the dark arts spells they had learned.
She placed a voice automated sound that would describe
"I would like the class the lesson.to review all of the things that you have learn so far, whether at home or schooling I expect you to use the spells on the dummies and not on each other."
"Next I want you to discuss what you are doing with each other and help each other learn things you are doing wrong. Any idle chat and points will be deducted."
THE CLASS IS TO BEGIN....NOW!!!!
