He's incredibly hard, but also really smart. He knows what he's talking about. Unfortunately, he expects the students to be just as smart, which can be hard. He's really supportive and friendly too.

He's a good teacher. He's sometimes tough, like the letters and all, but he really knows what he's talking about. I asked him what colour HUMAN MEAT WAS, and he KNEW. But he tried to make me dissect.
