For most chapter, I'm pretty sure I could teach better than they after watching 10 minute YouTube video

They are the worst professor of my time at Wisconsin. They has a class lecture strategy of constantly asking us to do a problem, and then saying that there isn't enough time to go over it. For anyone who ends up with the misfortune of Lahn teaching, I would recommend taking the practice tests from the last years over and over. That can help you.

Exams are 87% of our grade which is wild, I understand this is their first time teaching the course however this is not how you teach calculus 3 which is just the professor reading off desmos notebooks and it's extremely difficult to hear them with the echo in the lecture hall.
