Jonathan is an amazing prof and he made supplement videos for topics that were challenging in addition to many other resources he provided. Judging by median class grades on midterms and quizzes, I think that, for the most part, people got above an 80.

If you don't want a heavy course work load this won't be that bc of all the practice you'll need to understand concepts.

If you are interested in computer science, math, or logic, this class is for you and will be trivially easy. It can especially help with understanding topics related to theory of combination and binary logic (read: CPSC 121). If you are not interested in math or logic, then this will be a weirdly abstract class which can be hard to grasp and do well in. (AKA, not a GPA booster if you are not good with logic)

Read the textbook before class.
