Don't take this class/prof unless you absolutely have to. Certainly harder than 30A but as long as you fully complete HW, attend lecture, put 100% effort into labs (they grade labs fairly hard) then you will pass. I literally got a 50% on my midterm and a 40% on my final and still passed so you will be ok as long as you do the work, but don't actually expect to learn anything.
PSS and OH sections are almost always completely busy so I'd recommend talking to a friend whose taken the class before OR making friends in lecture to work thru practice exams with. The best advice I can offer anyone taking this class is to just complete everything. HW and labs can get super overwhelming since you're expected to do a lot of lab work on your own. Literally every single point counts in this class though so as long as you complete all assignments, you can pretty much fail the exams and be OK

This class was absolutely horrendous DO NOT TAKE IT AT ALL COSTS. The lectures were not helpful at all, I attended all of them and was thoroughly confused after each one. The PSS sessions were what got me through, but they are waaaayyy to crowded at often times you do not get your questions answered. The homework was also not helpful at all when it came to solidifying my understanding since the wording of the questions was confusing, it involved way too much coding compared to actual practice questions, and often asked you to write out explanations instead of solving anything. The labs were also a testament of how well you could code, not how well you understood the material. Shoutout to my TA who helped me with every question. The Final was a nightmare by itself. Nothing could have prepared me for it, I could have skipped the last month of lecture and performed the same. The questions were obscure and involved writing out explanations instead os solving; I only used my calculator twice during the whole test. The final asked about topics we never fully covered and omitted topics that the class placed heavy emphasis on. All past practice tests that were given were useless in preparation for this final, along with all material. Dr. Shevstov is funny, but that does not make up for all horrible this class was.

This class was absolutely horrible and it was the bane of my existence. The lectures are very confusing and Dr. Shevstov does not post the slides beforehand, which makes lectures unnecessarily more difficult. The labs were not helpful at all, since they were composed of coding, and the coding took minimum 2 hours outside of class time for me to finish, on top of discussion time. The labs did not at all contribute to my understanding of the class material, and they in fact waste time that I could have been utilizing to actually learn class material. Note that there was no coding on any of the exams. Additionally, the homework assignments were not helpful at all. The good thing was they were graded on completeness (not correctness), but it felt like a waste of time because the problems were often overly simple or unrelated to what we needed to know. The homework problems were from the textbook. Plus, the homeworks were horrible especially the second half of the quarter, since we started being assigned more than 20 questions per homework, and the last week of class before finals, we were assigned 30 QUESTIONS of homework, which was infuriating. The one beneficial thing was the Problem Solving sessions, so if you do end up taking this classes, you REALLY SHOULD go to these sessions because they provide good practice problems that are truly reflective of the material of the class and exams, as the questions are from previous exams. The midterm was good, as it was reflective of what we had learned so far. However, the final was horrible, because many questions asked things we had no clue how to do. This being said, although this class is unnecessarily difficult, it is possible to do well if a lot of work is put into it. I definitely recommend doing what you can to avoid taking the LS 30 series, but if you have to take this class, make sure to especially spend a lot of time studying for the exams, are they carry a lot of the class grade.

I’m not gonna lie, when I took 30a, I thought that it couldn’t get worse. However, Jane got out a pickaxe and drove her electric scooter past rock bottom. While Jane is a very fun professor, she is not very clear in her descriptions of class materials, and all in all attending lectures is not very useful except for sitting next to someone who actually understands what is going on. The homework often does not reflect what we are learning in class, and the tests to be honest don’t either. All in all, I would have to say that you should only take this class if you absolutely have to, and if you do, please take Jane’s class purely so that you can attend Problem Solving Sessions. The TAs and Las are very knowledgeable and helpful, and this is an excellent resource for learning the material (despite the fact it is supposed to be a review). Labs are fairly straightforward with coding, but they are very particular on what they want to see, so make sure to check with your TAs to make sure you are doing it right. I would not retake this class, but it helped to make me appreciate spring break, when I can finally dissociate it away, all the more (pressure makes diamonds smth, smth).

I TELL YOU I AM THE BIGGEST HATER OF EVERYTHING TO DO WITH THIS CLASS. WORST START TO MY CAREER AT UCLA. My TA, Pranav, constantly made my group feel worthless all throughout the coding, because if you think you will be prepared from 30A, no. I was a beginner at coding because it is never said it is a prereq or anything...but I was so confused every section and the only goat that got me through sections was Daniel our LA. The final was hard as hell even though I studied endlessly, some of the concepts had to have been written from the other Professor because Jane never went over it.

I will say that if you try your best to sit in front during lecture and PAY ATTENTION, Jane is not entirely the issue here. While, yes, the students are so disrespectful and talk over her, she is not a horrible Professor and is extremely sweet and accomplished (you must give her props for this). This class is a load of BS and I don't necessarily know if doing it with Bennoun (he is more thorough with the material) would have helped with exams.

Homework is pretty simple and based mostly off completion so that is good and workload aside from that was doable besides the ass labs. I'm just glad its over it was hell.

AVOID THE LS30 SERIES AT ALL COSTS. This series is consisted of fake math and it's honestly so boring. The final for this class was almost impossible considering the material we were taught in class. Jane did not prepare us at all for it. Also, the labs for this class were extremely hard and depending on how helpful your TA is, you will be very confused. I am so glad to be done with this series and would not wish it upon my worst enemy. Please do yourself a favor and take another math series!

PLEASE whatever you do, do NOT take her class. If you need to take LS 30 do not have her as your professor. She's a nice professor but I will say that she doesn't teach the material to the degree that the other professors do. Which means that when you take a final or a midterm you are going to see topics that she didn't teach. If you are expecting this to be an easy class I can promise you it is not. I had her class for 30A as well and the midterm we were completely screwed with the class average being 60% because she didn't teach most subjects on that test. It was so bad that she curved everyone's grade. This class you have to do a capstone project and it's fairly easy so don't stress about it. As long as you stay on top of homework, participation, and your labs you will pass the class. This is coming from someone who failed both test this term. If you can take any other professor I'd highly recommend. Also, it can be really hard to understand her most times and her test are just super unfair. This has been the worst class I've ever taken. A lot of the people I talk to about LS 30B who have other professors don't absolutely hate their lives like those who took Janes section. I hope this saves you!

ABSOLUTELY NOT AVOID HER. She is inconsistent with uploading materials and is very hard to understand. People would just talk over her and leave when she was still talking so it was pretty clear people don't like her. Even though she is incompetent at lecturing, self studying for this class wasn't too difficult either. Do the practice midterms and synthesize the slides (that she is very slow at posting) into notes. Be able to explain concepts, even the smallest details like oscillations and chaos. The practice midterms were similar to the midterm but of course actual midterm may be a little harder, average was a C. The final was hellish with some problems being concepts we never did.
Conceptually, I found this class easier than LS30A, same with the coding until the last 3 weeks. The capstone project isn't that difficult either just stay on task. Shout out to my TA Bella who helped so much with coding, our understanding and recapping the content we learned, she is excellent at teaching. Homework can sometimes be long, 1-2 hours but is manageable, just don't procrastinate. Overall, I wish I took another professor as she was bad at explaining and hard to hear.

AVOID THIS CLASS WITH THIS TEACHER. IVE NEVER BEEN SO MAD. THE FINAL WAS SO HARD AND THIS WOMAN DID NOTHING TO PREPARE US. I CANT EVEN DESCRIBE HOW ANGRY I FEEL. DO NOT TAKE THIS WOMAN EVER.

Don’t take the ls30 series if you can tbh it is not real math. In all honesty Steve or Jane are both not amazing. Honestly get rid of this department!!! They teach you how to the most basic examples and then pull some trick on the final. If it weren’t for my plf I do not know what i would do. Bring back regular calculus!!!
