Ronchetti is someone who truly cares about his students. Only in his math class have I rediscovered my interest in the subject. His lectures are always articulated clearly and the mathematical concepts are always easy to follow.

The WORST CLASS ive ever taken in my life. Avoid at all cost. He should be fired, I even went to the math department to have this done. He does not teach to the standards of UCLA, and by that i mean he is too difficult. We get it you're good at math, but im a STUDENT and this is a prereq for a lot majors. I changed my major after this class, 31B. I spent over 40 hours a week studying to fail every test, along with most people, however, the curve somewhat makes up for this. He's also a terrible professor and ruined my life for 10 weeks. He seems good at first but don't believe it or you will be in for a rude awaking.

Professor provides free online textbooks. He's passionate, patient, and very smart. He actually helped revitalize the little interest I had in math. Lectures are Bruincasted and lecture attendance is not required, but I highly recommend it. Concepts are covered beyond those explored in high school precalculus. He assigns weekly assignments due before lecture on Friday, and assignments are useful but can be tedious and long. Exams are also fairly difficult, and require a fair amount of studying.

This was my most work-intensive class of the quarter, but Ronchetti is a wonderful professor and I still recommend the class. I feel like I genuinely learned things in this class, and Ronchetti is honestly pretty adorable sometimes with how much he loves math. He's also apparently a chess world champion, so that's cool too.

Prof. Ronchetti's lectures were always pretty clear and easy to follow, and he always answered any question that anyone had. Half of the problems on the midterms and final were straight from the worksheets given out in discussion. The LAs were super helpful, though my particular TA (Abigail) wasn't the best at explaining things; I'm sure she's very smart and understands the material herself, but she was not great at explaining, and if I had any questions I asked the LAs instead. The homework is manageable and not very difficult. A very solid class overall in my opinion.

This class was just alg2 with trig in the last 2 weeks and he still managed to make it unnecessarily hard sometimes for no reason. Some of the hws were extra as hell and there's one every week even weeks with holidays and they're graded on accuracy not completion. Worksheets were fine the LAs and TAs will be really helpful and he uses the same problems on the tests as it says on his syllabus. His teaching style seems kinda complicated sometimes but if you're kind of familiar with the concepts you can follow along easily. He'll guide you pretty well on the hws if you go to office hours. first test was easy, 2nd test was a bit harder, final was hard but he used a lot from the practice material. also kinda hated his practice material cuz he always says to basically avoid half of the practice tests problems instead of writing up new practice problems. overall not the worst teacher you could have I guess?

This isn't the WORST class you could take, but he is definitely not the best instructor, considering the content of this class was not that difficult, but his way of teaching made everything more difficult to understand. Given that I have taken pre-calculus before, he would still find a way to confuse me, and I'd have to remember random things from high school to understand what he was saying. He goes fast and can give broad explanations, but then expects you to understand intricacies that he is bad at explaining.

Professor Ronchetti definitely knows his math and expects you to know it too. I took his 31B lecture over the winter and he directed the class in an order completely opposite to any other professor. He focussed WAY too much on sequences and series and that made the class extremely challenging. The practice midterms and finals he uploads prior to the tests are very difficult and he does not upload the solutions. However, he does go over almost all the problems in the OHs and classes leading up to the test. The only reason I could even barely keep up was that I took a similar class in high school.

I would recommend him only if you really love the subject and can grasp challenging concepts easily.

I took 31B with Ronchetti in Winter 2018. Be prepared. His class is NOT easy. If you do your research on him, you will find that he is a chess prodigy and mathematician, so his exams and his class reflect this. Many of his exam questions are concept based and often times required a lot of creativity and fancy algebra. However, he is EXTREMELY helpful. He is always willing to answer questions in and out of class. At times, I think he was too generous with the amount of questions he answered in class-- often times 15 minutes of just answering questions. Moreover, he held two hour long office hours twice each week. He is incredibly patient and friendly. A lot of students gave him a really hard time, but that's probably due to the stress this class induced. Would I recommend him as a professor? If you're creative and can absorb concepts easily.

Okay so this professor is genuinely a good guy, but I wouldn't recommend his class under any circumstance. There's homework every week, and a lot of it, and there's a quiz every 2 days. The midterms and final were hard as hell. I think I got a 29 on my final. I also rarely turned in the homework. This was my first class as a freshman and it made me change my entire major and really consider dropping out of school. And this wasn't just me, a lot of the kids talked about it too. My overall grade was a C- (i was shocked) but it kind of shows you that everyone in the class did so bad that his curve had to be extreme. Just save yourself the energy, pick a different professor.

I took 31B with this professor and he spent WAY too much time on sequences and series-- way more than other professors-- which is much harder than the integration stuff we did later. We ended up having to squeeze in all of the integration at the end making that also harder than it had to be. The class had a pretty generous curve, but I still had to study a lot for every test and go to office hours frequently. I also took a class in high school with similar content which is likely a large reason why I ended up with an A. He is not super nice when someone asks a question that he thinks is simple and his handwriting is terrible. Generally I think the subject matter of 31B is just difficult and boring and he is a new professor, so it was kind of a perfect recipe for a confusing quarter of math.
