I took this class because I found a reddit thread saying 115AH with him was a "solid 9/10."

He has an oppressive personality. He's funny during lectures but they too fast -- moving on from questions before we can process the information. He always has to run away right after lectures so you can't really talk to him. Homework takes 10+ hrs/week, and he deletes your Discord messages (yes, the class uses only Discord, not Canvas) if you ask questions about the homework that he does not like. The homework also has overly strict rules as to how they are submitted. For example, he says that only printing paper can be used. Someone asks in class whether line paper may be used and he said yes. Come Week 4, 1/3 of the class submits their homework on binder/notebook paper. He holds one up and says that "this won't be graded" and tries to move on with his lecture. When I stop him and remind him what he said, he said to "complain after class." Come the end of class, I bring the homework back up, again reminding him what he said. He then DMs me at 5pm saying that he disliked my "belligerant posture." Knowing full well that I was not even disrespectful, I apologize anyways, then remind him a third time what he said. He then said that line paper is not necessarily binder paper, implying once again that he would throw away our work. He then tells me off again saying that I wasn't listening to him and saying I had an "aggressive reaction." I apologize again and tell him that I would be dropping his class as I no longer felt safe with him anymore. He then tells me I'm overreacting and that I shouldn't make decisions "hot-headed." But no. I'm completely collected in my decision to leave his classroom and to end my suffering.

Try not to take this class with him. But if you do, buy some printing paper and a stapler, and form large study groups to work on homework problems together. And be careful around him. That's all I know.
