I was already familiar with the content so I didn't attend any lectures/discussions except the first one, although I always made sure to look through the notes. Prof Wu isn't (yet) a good lecturer, I have to admit that. But it's tough as Fall 2020 was his first quarter at UCLA and he had to get used to the online format. He's incredibly accommodating and responsive, which for me totally made up for that. Of course, I'm biased as I don't have to rely on lectures to understand things, but he's a great person and he truly cares about the students and thus I would still highly recommend him. If you already know the materials or don't mind looking on Youtube to learn, take his course.

Professor Maimaitiyiming is a terrific professor and his Math 151A was a great breath of fresh air amongst the cesspool of proof based, theoretical and sometimes vague math upper divs.
His lectures were clear and tells you EVERYTHING you need to know to succeed in the course.

Homework:
Homework was very straightforward, lifted straight from the examples he goes over in class, with literally some numbers changed. I actually got a 99% in the homework category, and I don't consider myself to be that great at math. Considering the homework category was a hefty 49% of the overall grade, having straightforward homework was a blessing. Plus he drops the lowest homework.

Midterm:
Just one midterm, worth 20%. Pretty straightforward as well, lifted STRAIGHT from his homework, with numbers changed. In fact one of the questions on his midterm was the exact same question on one of his homeworks.

Final:
Worth 30%, same idea as the midterm, however there was one or two questions that was a bit more difficult, while the rest were lifted straight from his homeworks as well.

Coding:
There are a couple of coding assignments, but they aren't difficult at all. The book has pseudocode for every assigned algorithm, and my TA actually did some of the coding assignments for us in section. Professor Maimaitiyiming specified that he does not run your code, he only looks over it, so my guess is, as long as you get the overall idea, you shouldn't lose any points on the coding.

Overall, terrific professor. Professor Maimaitiyiming has clear lectures, clear homework, clear exams. I would take him again in a heartbeat.
