Shu Liu is amazing, and is one of my favorite professors at UCLA.

Grading Scheme was 50% HW, 15% Midterm, 34% Final, 1% Evaluation Survey at the end of class. You could also drop the Midterm for the Final. HW's were very straightforward and he gives you more than enough time to do them. Exams are very similar to the practice exams. He records lectures, and is very accessible in Office Hours. If you have any coding experience prior to taking his class, you can put in very minimal effort and expect an A. I can't say enough good things about this guy, take his class.

For context, I had Kashefi for 10A originally and immediately tried switching to Professor Liu's lecture. He was super accommodating and let me in, although the class was all full. Liu uses slides, which is really helpful for understanding concepts/studying. His lectures are well structured and organized, and he really cares about teaching and helping us. He hosted extra office hours during midterms and finals week, and had a Zoom review session for each. His exams were fair. Though the content gets more difficult after the midterm, it's definitely still doable if you study and pay attention during lecture. Professor Liu is also so nice and helpful. Always willing to help debug or answer questions after lecture. Would definitely recommend him!

If you ever get a chance to take a PIC Class with Shu Liu, DO IT! He is so clear and very helpful with all questions. His lecture style is showing a concept, and then giving a few examples. He does lowk read off slides, but I don't mind/actually prefer that method. But, I had him for 10A and 20A and he is a really great prof.
