If you are taking this, it is probably because you are a physics major. I really don't know why else you would. This class was asynchronous for the semester I took it, which was probably the wrong choice for the department to make. Consequently, I think it was easy for the professor to fall into the fallacy of really fast-moving powerpoints. Consequently, the lectures were neither particularly clear nor engaging. Hopefully that particular issue won't be a problem again. Be prepared to teach yourself a lot of the concepts, but don't worry, because the Internet can essentially teach you all of the class (the textbook, on the other hand, is basically unreadable). This class is three discrete units: linear algebra, the tail end of Calc III (Stokes' Green's Divergence etc. theorems), and complex analysis. Almost all of it is computational, with some homework questions on developing proofs and a little bit of actual conceptual understanding needed to function in the final third. The problem solving parts of the exams weren't bad at all, but the True/False sections were horrible and often the class as a whole was better off guessing than really trying to answer. It is this section that essentially creates the variance in the class grades, because it rewards a conceptual understanding that was not covered in the computation-focused lectures and homeworks.

If it’s with Yen Do, only take this class if you have to.
He is a terrible lecturer and you won’t really learn much. His practice midterms are the same as the real midterms, so the averages for those are pretty high.
