Depending on your major, you may have seen this content multiple times before taking this class. The lectures are pretty dry, but they're informative and usually a good match to what the exams will cover. He doesn't cover any practice problems, so the lectures are all just theory, which does find its way into the exams. The textbook is alright, but it's not exactly great for example problems so the released homework solutions are usually the best bet for studying for exams. The discussions also give out homework answers (before they're due) so those are worth attending if you have the time. They're also recorded if you can't bring yourself to go

A lot of people freaked because there is little rhyme or reason to the difficulty of the midterms. I got wrecked by the 1st but did oddly well on the 2nd. The final was pretty hard though which is probably why I ended with a B+. But in any case, the exam questions are pretty reflective of the homework and lecture slides.

No major surprises with this class. Just do the homework and look at the slides more than the textbook and it works out well enough. BTW what I've written applies mostly if he maintains the current course format (posted lecture recordings, non-mandatory discussions, open book zoom-monitored exams, etc)
