Excellent professor! Very thorough explanations. I really can't say anything bad about her except that her lectures can be pretty slow sometimes. For midterms and finals, just study the practice exams and you'll be well prepared.

Literally, avoid Shevstov at all costs. I'm serious, the 30A/B series is a freaking scam from our school. It's a fake math series and you're going to be better off taking the 3 or 31 series. This whole series was created to spite the math department basically and it still isn't accepted for some graduate schools; however, the 3 and 31 series are.
But, really from what I've heard recently, they've made the 30 series harder since they actually test on coding now. Shevstov herself is a pretty bad lecturer and 99% of the time you will not be able to understand her.

Do not take it with her!

Do not take shevtsov, this class was so hard, the amount of homework was insane. I techinically had to teach myself the topic. Most of the time i couldnt understand what the professor was saying and she never had good slides, everything was so vague

Jane is a good professor however, I think her classes are much better when they are confined to zoom and not in person. I spent the first five weeks online, and the second five in person and it made the world of a difference. I aced the content that was taught online but struggled a lot with the content that was taught in person. The in person lectures can often be incredibly slow, confusing, and chaotic. Jane has a speech impairment which makes it really difficult to understand her in a massive lecture hall. 90% of the time the mic was set too low to understand her regardless. She's also physically unable to write on the whiteboard, so an LA did it. Our LA often wrote wrong things on the board, or would write so incredibly slow that it was hard to focus on taking down notes from him and listen to Jane at the same time. The zoom environment was much less distracting, and her slides were so helpful.

Homework was extremely overbearing and annoying. The textbook didn't provide enough information to help you figure out how to solve it, so I often put down stuff that I made up. It was graded based on completion, so as long as you put in the effort, you should be fine.

Labs were also pretty hard. The first 2 weeks or so is spent on nailing down basic concepts of coding and then it progresses into harder LS 30A related coding. I frankly thought it was ridiculous that they thought a coding language could be taught that fast. Try your best on the labs and try to find a partner to do it with because those are graded on correctness. However, the Lab Practical in Week 10 is extremely easy, and is only tested on coding material up to about week 5. Its an easy 100 and also an easy way to boost your grade.

Her problem solving sessions are AMAZING. I would highly recommend attending them before the midterm and the final as she lays out everything clearly and you often don't have to study those concepts again because it'll become so clear. The midterm was extremely easy for me, but the final was super hard and confusing. Be sure to practice the practice tests that she gives out as the structure remains the same for most tests.

Overall, Jane is not a bad choice but if you can get it with someone better, I would go for them. I'm in a 30B class this quarter with another teacher and its a complete 180 (in a better way). Good luck!
