Professor G is a great professor. He cares a lot and will give you a good grade if he sees you trying. In office hours before the final he basically gave us all the questions on the final. His grading is super lenient and he tries really hard to help where he can. Taking him again next quarter.

Lets you bring 2 pages of notes to tests, EXTREMELY, extremely lenient grader, and releases practice problems the night before the exams that are basically exactly the same as the ones on tests. One of the greats, his classes are not fail-able, ignore what everyone says. Just show up to 2 classes: the midterm and final, and you'll pass I promise.

Didn't know how to pace the course for Summer Session B, so we were told to attend two extra lectures at 7:45 PM during our finals week. High expectations for students' understanding while simultaneously leading disjointed, confusing lectures. Luckily, he's a very lenient grader. He's a good guy, but would avoid in future upper divs.

Karen is a genuinely good person and although I don't always understand 100% of the lecture material, he always tries to make it more entertaining. Would take him again, but the class isn't easy.

If you have a late pass time, just suck it up and take this class, but avoid it if possible. The lectures are utterly incomprehensible, but attendance counts a lot. Participating isn't hard if you just spam questions and hope a few are "profound." If he can put a name to your face by the end, you'll get a bonus.

10+ hours of hw each week, last-minute midterm project idea change, mystries bonus point to face he recognize, randomly use the last 10 mintes of class to cover some ph.D. level topics:) Yah, he might not be the best professor you take, but the cheapist(maybe not) and most nearest-to-your-dorm(100%) 1rcus porformer in your boring 4-year service.
