Ian watched as the professor put snippets of their answers on the board. He was pleased that his mention of muggle chemistry made the cut. Then the professor made the words change until there was a coherent sentence on the board summarizing what others had said. He began to feverishly scratch out the words on his parchment, to save it for posterity (and later, test-taking preparations).

The professor asked what types of potions there were. Certainly it was a bit odd to be asked so many questions, but Ian guessed the professor had a reason for ensuring they had a theoretical understanding of potions. Something must have gone BAD wrong somewhere.

Ian listened to the others and thought to himself this was an overly broad question. I mean were types based upon ingredient, function or some other thing. Perhaps he could break out some Socratic method and start questioning the questioner. That might however upset the professor unless he declared it was for clarification. Ian decided that he'd just sit on his question and if after the next response from the professor didn't clarify, he might ask.
