He is just perfect! One of the best professors Ive ever met: Easy exams, super generous curve, low-workload, and well-organized lectures. Also super helpful during office hours! Take Math135 with professor Flynn and that's absolutely an easy free A.

Patrick is a kind and approachable(also sweet and cute!) instructor who brings a lot of enthusiasm to the topics he enjoys, making him engaging and easy to connect with if you want to dive deeper into the subject matter. As a senior, I find his teaching style very appealing, as he explains not just what to learn but also why it matters and how to apply it, whether in mechanical physics or more abstract concepts(for me it's necessary for exploring PDE/ODE in future interest). However, his pacing can sometimes feel inconsistent—occasionally moving too quickly or too slowly and occasionally skipping necessary explanations. The course includes 2 midterms and 1 final exam, and I found his exams to be fair and reasonable, though sometimes tricky. They are based entirely on the material covered in class, so if you thoroughly review the notes and genuinely understand the homework, you should be well-prepared to earn a good grade(not kidding!). Patrick is also very generous with partial credit, which I appreciated. The biggest challenge in the course was that the lecture notes often lagged behind the pace of the class. That said, Patrick provided notes in LaTeX format that were clear and helpful. It’s worth noting that this might have been his first time doing this kind of notes so some growing pains are understandable. I believe he’ll improve in future iterations because of how much he genuinely cares about his students’ learning. He is always willing to answer questions via email or during office hours, and he’s great at explaining concepts and providing thoughtful suggestions. On top of that, Patrick has a good sense of humor and does his best to help students relax during stressful times. The homework typically consists of around 10 problems per assignment, might be time consuming but worth to do.

Great Professer, but i didn't do anything all quarter so I kind of deserved that B. I got an 88 and a 87 in the midterms (got one question wrong on both) and since the exam was really easy that kind of killed any chance I had to get an A especially since I got a 68 in the final- curved up to an 88.

I never leave reviews - but everyone else leaving a review listed an A as their grade and I thought I'd round out the responses.
For context, I'm a 2nd year at UCLA and this is the second class I have not received an A or A+ in. That being said, I was on track to receive an A in the course until the final exam.
Proceed at your own risk with prof Flynn - clearly it can go well given the other responses, but the structure of his grading scheme means that you are completely relying on exam grades (as opposed to having homework / participation credit as is typical in an intro class). There are homework quizzes that you take in your discussion, but (at least for me) it was super unlikely that you'd be able to receive a 100% for homework.
Anyways, I agree that if you took BC Calc in high school you're probably fine with Flynn. If you didn't, though, I'd just wait another quarter and take it with a more experienced professor (and grading structure).

Flynn is such a kind and understanding professor. This was his first quarter teaching so the pacing of the class didn't feel consistent (which is understandable---again his first quarter teaching) but we was aware of that and often accommodate for that. For example, we rushed the inverse trig unit so he provided the formulas for that unit on the midterm so we didn't have to memorize it. I think it's pretty clear that he's open and receptive to student feedback, and a lot of my friends enjoyed his class (they all said positive things), as did I. I would definitely take it again.

The final was relatively difficult in comparison to the midterms, but I thought it was still pretty fair. The class average was a C+ and I think that's mostly because the format of the exam was different from the midterms and quizzes. Typically, the exam content would be pretty similar to the homework questions so if you did the homework over and over again, you would probably get a pretty high grade (as long as you study a decent amount, you should be fine). The final, however, was more about applying the concepts we learned because it included questions that we didn't really solve before---it was fair, but just very different from what we expected. Everyone came out stressed. Anyways, he curved it REALLY generously so the average student got a B+/A-.

If you took AP Calc BC in HS, you are totally fine. Even though Flynn's teaching may have been a little unclear and based off the book (with some random proofs you end up not needing during lecture), it is his first time teaching I think and so I'm sure he'll get better as time goes on. After week two I stopped going to lecture completely and I was totally fine. With that being said, I loved the structure of his class. Your grade basically consists of quizzes, 2 midterms, and the final. The quizzes are just the homework problems he assigns (which aren't for a grade but definitely the foundation of his quizzes and tests SO DO IT OVER AND OVER) with constants changed. The midterms were easy too if you went over the homework problems. The final was a lot harder for some reason but he curved it by twenty points at the end so I ended up getting a 100 on it which is crazy. He also curved the quizzes for some reason even though I'm pretty sure people did good on them. He is just really lenient with grading and I honestly still felt like I learned the calc I wanted to learn from this class. Would def take again. Review the organic chemistry tutor if you forget some integral or series stuff. He also reminds me of John Green (big plus).

Although the lectures were extremely similar to the textbook and weren't super clear, his office hours and the overall structure of the class was nice. The quizzes and both midterms felt fair and were exactly what you would expect. If you did the homework, you should be able to ace them since he wouldn't put any material you didn't learn on them and the depth of the questions were similar. One exception to that would be the final. I redid a lot of the homework questions and studied days in advance but that final had almost the entire class in there at the end of the three hours because of how difficult it was. I think a lot of the questions could've been reasoned through with the concepts we learned in class, but many were more in depth than we've seen on the midterms and quizzes which was why the final was so difficult. Fortunately, he did curve the final as a result of this even though a C average in a final is standard. Also, as someone who didn't take Calculus BC, it was hard to understand the concepts being taught but going to office hours (TA and prof's) and watching videos online helped a lot.

overall feedback:

- prof is super nice and often funny and a very understanding guy
- flynn not the best lecturer, lecture is super heavy on theorems, definitions and formulas without much application
- professor leonard on yt supplemented any confusion from the lecture and did ample practice so highly recommend
- weekly quizzes with problems pulled directly from the homework with constants changed
- homework is not due but heavily encouraged due to the quizzes
- midterms were both fair with problems very similar to the homework
- the final was insanely difficult but patrick was very nice and curved it by 20 points
- if its an option, take the later discussion day since that's when the quiz will be and you'll get more study time
- you can succeed in this class by just doing the homework over and over again until you memorize all of the steps on how to do all of the problems
- for our final he allowed 8.5*11 cheat sheet front and back

overall patrick was super nice and funny and wanted all of us to succeed. although he was not the best lecturer, i would take the class again because there was no due homework, the tests were easy, and i was entertained by him during lecture.

Math 31B is a pretty standard calculus class, so if you've taken AP Calc BC in high school, you should be completely fine. The midterms and quizzes were representative of the material and were fairly easy. The final, however, was pretty challenging, and many people did not do well. However, Professor Flynn ended up curving the finals by 20 points so everyone would receive a passing grade. The professor is very approachable and understanding, even though he's not great at lecturing. He mostly just reads off the textbooks and does not dedicate enough time to practice problems. Overall, Flynn was pretty easy (at least compared to other 31B professors), and you can definitely earn an A in his class if you put in a decent effort.

This class was definitely difficult, there is no doubt about that. However, as long as you pay attention in class and make sure to do the optional homework so that you do not fall behind, it is manageable and doable. There are weekly quizzes in discussion section and the midterm and final, these make up your grade. I thought that the final was much harder than I was expecting it to be but the professor gave us a friendly curve which was appreciated.
