Professor Flaumel entered the classroom, and started calling each of the students up to his desk, where he cast a spell on them, writing down the results on a piece of parchment. After all the students were measured, they were placed according to the grouping on the blackboard. Once they were in their groups, Professor Flaumel came over to Neville and Harry's group, handing each of them a list of potions to prepare, as well as instructions for an exercise program they are to follow. Although there was a certain amount of groaning, they all went to the ingredients cabinet and began to prepare their potions.
