It's a lot, but the pacing is good and I personally like the way the professor teaches.

It's a lot of math, but you learn the basics of quantum mechanics! Very difficult, and not super useful if you're not planning on doing anything with it, but interesting.

He sometimes talks about real-world applications, and that's interesting. A lot of the class is just math and descriptions of how a particle might work in a given situation, so the more... physical description/use is nice to see. He posts videos that give a quick description on how to start the homeworks, so that's nice. He's also very available to email if you need help.

Don’t stress about it. You won't get good grades on the homeworks, but make sure you understand the key and review the problems and you'll be fine on exams.
