Professor Yin's accent may be a bit of a shock at first, but once you get used to it you begin to see that he is in fact a good professor who knows what he's talking about. He makes himself available for questions in office hours quite often. Yin's lectures are very dry, but he has a quirky personality that you begin to admire the more time that you spend in the class. If strong accents are a no-go for you, I'd say avoid this class. Otherwise, I'd take it again.

Put my damn grade in

This guy's accent is unintelligible at first. You get used to it after a week or two, and then Yin is pretty much your standard lower division lecturer. He's not very engaging, but he gets the necessary info across. His tests aren't too bad, and he does prepare you well for them.

Yin wouldn't be my first option if I were to retake this class, but by no means would I advice against taking him.

Prof. Yin's lectures are boring and nothing short of frustrating to sit through. Often it feels like he himself is not quite sure where the lecture is going or what the material he is covering is. Multiple times during a lecture he will have to stop for several seconds to understand his own notes, and frequently makes mistakes and has to go back and fix his mistakes on the board - which is frustrating when you're trying to take notes.

The homework is easy and not even close to the difficulty of the exams. To prepare for the exams, go find exams for other, past 32B classes.

Bottom line is: I would not recommend. This guy made me miss Chayes.

Right off the bat: if strong accents are a hard limit for you, do not take this guy. Otherwise go to class, do your homework, and you'll be fine. Exam questions where on par (and often times easier) than homework problems. He lets you know what topics will be on exams and post practice exams. His lectures are average, but he is clear and provides plenty of examples. There are no surprises in this class; you'll pass it if you don't blow it off. I also liked the guy; he had a pretty unique personality.

The grade breakdown was 20% Homework, 30% Midterm, 50% Final. We only had one midterm, but I think that is because it was a summer course.

Prof. Yin lectured mostly from slides from the publisher of the textbook; if you can learn well from wordy slides, this class may be for you. The professor was challenging to understand at some times, but the slides and textbook are decent. A full page of notes were allowed for exams. It looks from the grade distribution that the class was curved generously.
