Professor Bennoun is goated. Mbappe in the World Cup final type of goated. You only get one homework and one lab assignment per week, which is completely manageable. Midterm and Final is fairly easy to study and prepare for. Most learning is done by doing the homework. If you do the homework honestly and look at the answers after the due date then you should be fine. The coding is not too difficult, you just have to be patient with it. Overall, I would take again and recommend, but this class is not for those who like to complain when faced with a bit of difficulty.

He taught LS30A so good that he tricked me into taking 30B

Professor Bennoun is an amazing professor and he is generous. He switched our bonus from 0.5% to 2.5% after finding out that Professor Shevstov let her students gain back points for their midterm. He's great at teaching, but please don't think this class is an easy A. A lot of the reviews from the past were from COVID so they took it online. In 2022, the grade adjustments were made so it was also easier for them.

Textbook: You don't need to use it all.

Lectures: Go to the lecture and make sure you pay attention, especially during the clickers. A lot of the concepts from the lecture show up on the midterm. When Professor Bennoun explains concepts, make sure you understand them and you're able to write down what the concepts imply when you take your tests.

Homework: Going to the lecture alone wasn't enough for me to complete the homework successfully. I went to office hours each week. I highly recommend Micah Vinet's office hours if he's still a TA by the time you see this. He has the most students coming, but he does the problems on the board and it starts to make so much sense. I received 100% on each homework assignment AND I understood everything thanks to office hours.

Midterm: It was so bad for me. I got a C- and I thought there was no chance of me getting an A, let alone an A+. I studied a lot, but I feel like I didn't study right if that makes sense.... The practice midterms were not enough and were way easier than the actual midterm.

Labs: The labs were easy at first but they got pretty difficult. Make sure you try to do as much as you can during lab sections and don't be afraid to ask your TA for help. It's their job and all of them are friendly.

Lab Practical: The lab practical was easy because I studied the past labs, but it took me a while to get the hang of it. Start early and keep practicing until you feel like a pro.

Final: When I flipped through the final, I was so relieved. I think Bennoun and his team realized that we struggled a lot on the midterm, so the final was fair. I got an A on the final and I studied by going through the past homework, doing the practice midterms, and attending office hours. At one point I attended four office hours a day. It was a lot of hard work but it was worth it in the end. Also, the TAs are so generous when it comes to grading the exams.

The reason I got an A+ in this class is because of Bennoun's grading schemes. Two grading schemes take away the midterm and increase the final exam percentage from 35% to 60%. If you do badly on your midterm, don't think it's over. An A in this class is so doable, but it's not extremely easy. Good luck!

Dr. Bennoun is a very helpful professor. He speaks clearly and is easy to understand. He teaches topics from the basics and builds it up so it is easier to grasp the concepts. The class is generally easy, however the concepts and the coding can definitely be a bit challenging to grasp. I'm taking him again for LS30B next quarter because my experience was so positive! And if enrollment is anything to go by, his class always goes away first.

I'm convinced that this man's spirit animal is the GOAT.

This class is NOT extremely calculus-heavy, more-so applications of those concepts in actual biological scenarios. The first couple of weeks had almost no relation to calculus so if you're behind, it's not too big of a deal. The midterm and final were extremely easy if you actually understand the material (don't memorize the formula, know why they work).

The python coding labs are not as challenging as you might think! I had absolutely no prior coding experience and still managed to breeze through them. The trick is to actually READ the labs, because they often give you the answer and you just have to reapply it to the context of the problem. The labs can be pretty engaging and fun with the right mindset, and they're really good ways to strengthen your problem solving and logical skills.

Professor Bennoun is an excellent teacher and a very considerate person. If you can, I would highly recommend attending his office hours, because he can teach the material efficiently and help you UNDERSTAND the material instead of just knowing it. Due to the TA strike, Professor Bennoun made two critical changes: replacing the lab practical with the lab grade (essentially increasing how much labs were worth) and changing the cutoff for an A from 93% to 90%. In my opinion, this made the class a lot easier (almost trivial) but it goes to show how considerate this man is. Even if you're not skilled with calc/coding, this class is really manageable and I'd highly recommend taking it with Professor Bennoun.

Only take this class if you already have experience with calculus!! Bennoun is a kind, good lecturer. However, his tests are unfairly hard and he often gives long homework assignments that feel like busy work.

LS30A was definitely a struggle - this was pretty evident based on the overflowing office hours that kept increasing in attendance as the quarter went on, and sentiments from friends/peers. This class is not curved, so you really need to have a solid understanding of all the concepts to do well. The midterm (for F23) was extremely challenging, like some others mentioned - I studied literally so hard for it, thought it was difficult (everyone did), and got an 81%. However, Professor Bennoun has 3 different grading schemes that you can use to get the best possible grade in this class - which is really nice. I got a 99% on the final (I thought it was way easier than the midterm), so I was able to pull my grade back up using a different scheme. The lab portion of this class is also pretty challenging, especially for people with no coding experience (basically everyone). They start out pretty simple and guided with a lot of instructions, but they get harder pretty quickly with less instruction and more "figure it out on your own"! It also didn't help that labs were almost nothing related to the class/lecture content. Therefore, I thought the lab practical (the coding "final" of the class) was pretty difficult, but I still got a 90% somehow through generous partial credit, I guess. Ending with some tips:

- GO TO MANY TA OFFICE HOURS. Pick your favorite TAs, and go to their OHs every week. And don't just go to get answers to your homework and labs. Try to really understand and learn from office hours, because if you're just copying the TA's answers, you won't do well on the exams. You have to know what they're doing and be able to replicate the work/concepts yourself.
- Study consistently for this class - try not to cram before exams. Review your lecture notes after each lecture, make them more organized, and see if you understood everything.
- Try to get help on and understand the labs and the *meaning* of the code. Again, you can copy code from peers and TAs who help you, but you'll have to understand it when the lab practical rolls around in week 10.

Overall, an interesting and doable class that requires a lot of hard work and persistence. I did have a breakdown in one LS30A lecture this quarter because I was so overwhelmed. Just know it'll all work out and be fine in the end - all you can do is study hard and try your best. You got this!

Bennoun is a great guy, but the class itself isn't really that great. His lectures are easy to understand because it's in a fill-in-the-blanks-as-I-go format. However, the exams are quite tough and kinda sucked. Grading scheme is just like LS30A, but this is definitely a step higher in difficulty, so if you plan on taking this class be wary that it's not as much of a walk in the park like 30A. Homework is pretty mediocre, takes at most 1-2 hours if you know what you're doing, same textbook from 30A. Labs in my opinion are kind of useless and feel more of a separate thing. While they do cover the course content, it's mostly about coding functions for theoretical systems that you won't really see on your exams. There is a capstone project at the end for labs where you make your own system and explore it, so pick wisely who your group is going to be. It's also reliant on TAs and LAs to help you process what's going on in the labs.

I know I probably got a C for this class, but it's mainly because I got a C on the final and it's worth 60% of the grade because I did worse on the midterm.

TLDR class is okay, exams are not that okay so study for it, labs feel like they're kind of a waste of 2 hours of time.

The LS30 series in general just sucks, but Professor Bennoun is not bad. Weekly labs and homework assignments are do-able, although the coding can get pretty difficult sometimes. The midterm was fair, but that final...woah, it was crazy hard. The capstone project also seems oddly placed considering this is a math class, but it's easy enough. It really just depends who your group is, since the rubric is pretty specific. Would've much rather taken actual calc than whatever fake math this is. I actually started to dream about matrices at some point, 1/10 don't recommend.

The professor himself was good, he is understanding and is okay at explaining things. But the material just did not match what we saw during the midterm and final. No amount of preparation could allow someone to do good on these tests because of how poorly they are written, and the test are basically your whole grade. It was really unfair, and it you get to choose between the 30 series and 30A, take 30A to save your GPA.
