Professor Han is a really sweet person. She has the class take weekly quizzes and have graded assignments due. These assignments helped me stay on track all quarter long. Going to her office hours I expected to get more clarification and it personally didn't help me as much as I thought but the TAs did help with that. Professor Han makes sure to go at a pace everyone can follow and doesn't fall behind.

Professor Du is a sweet professor. She genuinely cares about students and despite preferring in-person classes more, obliged to move to Zoom during the protests because the majority of us voted for it. Our final was also at 8 AM and she offered snacks for people who didn't get to eat/have low blood sugar. There are six assignments and a quiz every week for each chapter. The chapter quizzes are unlimited attempts and the assignments come straight from the lab portion. Han is straightforward and everything you need comes from the slides; I'd say lecture isn't totally mandatory (since she kind of just reads from the slides) but the lab portion is because the assignments and exams are heavily centered around the program we use, Jamovi. TA's usually make slides for the labs if you can't make it but I'd say being there for the lab is more helpful than following some slides.
