The course load for this class is difficult but the professor taught it well while keeping review sessions to strengthen the concepts.m

- funny professor (once let a student teach b/c he was tired)
- curves exams
- allows cheat sheets (index card size)
- lectures not required nor discussions
- lectures can be a bit confusing and hard to hear and see if at back of class
- weekly homework sets due sunday

taking 31b with professor ding lowkey saved me 🙏 he was a pretty fair professor and although 31b itself is quite difficult (imo) his class was manageable. his recorded lectures were kinda hard to understand sometimes but not bad enough where i had to attend lecture. as he's a new professor, he was very receptive to student feedback and adjusted the difficulty of exams according to our previous performance and feedback. i got a 96% on midterm 1, an 84% on midterm 2, and an 85% on the final. he didn't allow a cheat sheet on the midterms, but allowed index card(s?) on the final which was super helpful with all the sequences and series content. because he was new, he also made a policy that final grades that were 90+% were considered As but i'm not sure if he'll continue to do that. homework is basically a guaranteed 100% so just do very well on the first midterm as the content is much easier and try to get around an 80% on the final and you'll be fine

I really enjoyed taking this class! His lectures were well organized and he always posted lecture notes in case you had to miss a class. He was very approachable and helpful during office hours. I thought 131A would be challenging but I believe I really understood the proofs and the content. Overall, I would definitely recommend taking 131A with Prof Ding.

Details on the class:
Homework (drops lowest score), 2 midterms (can drop 1 midterm), and a final. The homeworks were manageable given that we had a week to complete it. The exams were very fair and his practice exams and notes are very helpful.
