He is an incredibly articulate and helpful professor who gives very engaging lectures. Even though the material was very challenging for me, I thought that he tries his best to make your experience as easy as possible. He is the best math teacher I've had so far and I would definitely recommend him.

I got a C+ in this class, and got my butt kicked. But, if I could go back in time and take a different teacher, I would't. He was an amazing professor, and I would highly recommend him. His midterms are thorough and sometimes touch on stuff from earlier on in the class and the final was difficult, but everything was fair. He is the best math professor I have had at UCLA, and highly recommend, even though I got a C. THAT shows how good of a teacher he is.

Harrop-Griffiths is an absolutely incredible professor. I had heard various horror stories about 32B and also did horribly in 32A, but his clear lectures and very reasonable (although not easy) tests made this class a breeze in comparison. Snazzy British accent, too.

He could explain the concepts very clearly. Highly recommended.

Benjy is a legend and a god. Even apart from his neck beard and tight pants, he is an excellent teacher. He made this class so easy to understand, and I hardly had to study outside of class. He's very good at helping you understand what each integral actually means, and I was a huge fan of how he structured the class. A lot of the teachers started off with triple integrals and disgusting equations, but Benjy starts with one variable and helps you progress to three variables. With all the practice with the different integrals, even the most disgusting equations were very doable. Highly recommend this teacher.

Ben gives some of the most clear lectures I've ever had in a math class. His midterms are very fair, and while I did very well on them (near perfect scores), the final was a completely different story. The final was HARD and I did pretty badly on that, so I walked out with an A-. Beware that a lot of things that you learn in 32b are very similar and thus very easy to get confused with (Green's theorem, Stoke's theorem, Divergence theorem, etc) so make sure to spend that extra time to get everything clear. And lastly - go to class since his lectures are worth going to.

Ben gives really clear and organized lecture, and his explanation for abstract concepts are very understandable. He organizes the course material in a special way to help us understand. His final is harder than the midterms, but they always follow the structure of the practice exams and are not tricky, so it's pretty manageable if you put in a decent amount of time.

This class is hard. Harrop-Griffiths makes sure you learn your stuff, and if you fall behind you pay the price. He's a pretty good lecturer and his homework is really time-consuming, but it's a good indication of the level of difficulty of the class.

The midterms were okay, definitely not easy. The final, however, was just another level. Straight up the hardest test I have ever taken. I didn't really prepare well for it at all, so it was kinda my fault, and it really tested how much you understood the topics after the second midterm (Stokes/Greenes/Divergence Thm). I got a 65, and that was the average as well. This isn't a class you can fool around in and get by, unlike other classes such as 32A, 33A, 61, etc, because there is just so much freaking material to cover, and it all builds on one another. A plus is that Harrop-Griffiths uploads everything to gradescope, is good about regrade requests, has this sick accent, and made a really cool snapchat filter for his final. Honestly, looking back I can say the class was pretty fair, especially the exams, but you really have to know your stuff. My advice: don't fall behind, really understand the stuff after the second midterm, and do a ton of practice exams. If you are taking this class with other STEM classes, honestly prioritize this final because it is harder than most other math / physics / CS classes here at UCLA.

Harrop-Griffiths was a terrific lecturer who was able to simplify complex concepts effectively. Homework can be tedious and difficult, as you have to write complete sentences. Midterms weren't too difficult, but the final was definitely a surprise. Overall, he made 32B pretty tolerable, given that it's the hardest lower-division math class.

This class was pretty hard but I can't blame the professor. He knows his stuff, lectures clearly, and is very approachable. The content of this class is just pretty annoying and tedious. You have to keep a lot of different stuff straight in your head, much more than 32A and 33A. That means that you have to be thorough about the concepts and homework throughout the quarter. It's not a class that lends itself to cramming. The stuff on the midterm was doable if you really know what you're doing, but if there are holes in your knowledge they will be exposed. The final was quite hard, the average on it was about a 70 and the class wasn't curved. For that reason, I wouldn't sacrifice one of the midterms in the hopes you can drop it and it won't matter. I got a 90 on the first midterm, 40 on the second (LOL it wasn't that hard I'm just an idiot) which was obviously dropped, an 82ish on the final, and ended up with a B.
