goat professor. easiest final ever. notes are extremely organized and closely follow the textbook. allows cheat sheet on exams. he explicitly states that he will make the next exam easier if the previous one was too hard. he has an accent but imo manageable

Overall I liked 31B taught by Professor Li but I wouldn't say this is an easy class.
Good things about this class:
1. The professor is very helpful, he replies to your emails in a timely manner and is often willing to stay after class to answer your questions.
2. Workload is manageable, he gives less work during Thanksgiving break/midterm week.
3. Professor Li is genuinely a nice and chill person.
But there were things that went not so well:
1. Classes are not recorded or broadcasted.
2. Midterms were hard but the Professor was generous with partial credit.
3. The professor's teaching could've been clearer.

Just take him. Super chill guy and usually pretty funny, especially for such a large lecture. Notes are available and he records lectures. Sometimes, his accent is hard to understand, but he is very accommodating and hosts so many office hours. He's also really available by email where he is very clear.

The math department screwed his class over by limiting the number of As he gives out, but his tests are very clear and not surprising at all, as they come with practice examples, he gives partial credit and he allows for regrade requests. Most of the questions pretty closely resemble the examples he does in class.

There's very little wasted time in class because it's fast-paced, but it's not boring. Homework was slightly more difficult, but not impossible, and each assignment was worth 10 points. 8 of those points would be for completion, and 2 would come from a random problem the TAs would grade.

Grading breakdown: 20% homework, 25% midterm 1, 25% midterm 2, 30% final OR 20% homework, 35% best of your midterms, 45% final, whichever is higher.

He pulled out a tree branch in class to point at the board with. 10/10 recommend
