Benjamin Harrop-Griffiths is a great math professor. During lecture, his explanations of theorems and concepts are succinct, followed by five minutes for us to do a practice problem and then watch him go through the problem. Just by going to lecture and doing the very helpful homeworks (some of which do take a while and I recommend starting them as soon as you can), I felt extremely prepared for Ben's VERY fair exams. When he says that the midterms take one hour, he's telling the truth. Exam problems are similar to homework questions, but sometimes involve a little bit more thinking outside the box.

Apart from math, Ben is a super funny guy and his English accent makes class super engaging. He's extremely helpful at answering homework/lecture questions on his Slack channel, and you can tell he really cares about making the class effective and accommodating.

He is one of the best professors I have ever had at UCLA. His lectures are clear, he tries to make his lectures engaging (which for some topics it is quite challenging), his exams are all fair, and he is extremely helpful at OH.
I would take him again for any other class.

Griffiths is the best math prof I had at UCLA hands down. He is extremely clear with the material and relates it to easier-to-understand concepts. He is very generous with points so much so that as long as you put something on the paper you will get a good amount of partial credit for the midterms and final. The material was interesting and he didn't take the class too seriously (you didn't need to memorize every single textbook definition for integration but rather just needed to know how to apply it). My only gripe is that the final was worth ~ 65% of the grade on the second-grade scheme, which is quite large considering it was only 8 questions (8% of your final grade per question). That being said, I was at the higher end of an A- and he ended up giving me (and some others) an A for the work. Overall, great and personable professor who will be sorely missed as I believe it was his last year teaching.

Thanks again, Professor.

Professor Harrop-Griffiths is great, highly recommend. He took the best parts of Zoom classes (chat, polls) to augment the in person classes using Slack. With the lectures channel in Slack, students can ask questions through the "chat" without interrupting the entire 200 person class. Polls on Slack were also used for plenty of practice problems during lecture, which were super helpful. It's tempting to zone out during these practice problems. Don't. The professor also posts lecture slides before lectures, and the notes from class are posted afterwards (notes are digitally written on top of the slides during class, which makes it much easier to read than a chalkboard!)

Homework (10%) is graded similar to how it's graded in most of the other lower div classes, as in, partially by completion, partially by correctness. There's a channel for homework questions on Slack. Join the class Slack early in the year so you can ask homework questions to the professor and TA's! The Slack is also where announcements and test info are posted.

Midterms (20% each) can be difficult, so definitely study! Professor Brown posts multiple practice exams. Go through them for real! Set a timer and put away your notes save for a single side of paper of equations (you get to write your own equation sheet for exams!). And then if you have time, go through them again! Solutions are provided; actually go through them fully.

Final (45%) is a large portion of the grade, but the material shouldn't be too unpredictable on average. Many practice exams are provided, so again, these are really helpful. Two sides of one paper of equations is allowed for this one. Very doable if you study the practice exams, previous homework and worksheets, book problems, etc.

Overall, this is a great class, and although it's not easy, it's also not too hard, and the professor is good at teaching and the class is interesting. You'll do great!

32B is hard. Really, really, really hard. Do not under any circumstances underestimate this class. Don't fall behind. Don't ease up halfway through like I did. This class is hard from week 1 to week 10 ,if you're struggling in week 2 things WILL NOT get better. The material leans heavily on 31B (only the integration part not series) and 32A, if you did not fully learn both of these you are starting off at a disadvantage so enjoy playing catchup. Obviously, 1st quarter coming back from Covid it's hard to honestly gauge, but this was without a doubt the hardest course I've taken in my life, and it's really not even close.

To get an A you need to do the homework, and I mean DO the homework. Don't copy. Don't halfass. Sit down and do each question and actually understand the entire process before moving on to the next one. Then a week before the test relook over the homework and do other problems in the book similar to the homework problems, then do the practice exam(s) the day before the test. I would say go to lecture but I actually probably only attended about half of them, but I don't think they would hurt lol. If you don't wanna attend next best thing is Khan Academy. Not only do you need to know the math but you're going to have to have somewhat of knowledge of what is physically happening , which is hard in 3D space.

Anyway, Harrops. He's alright. Not out of this world amazing as some claim. Not horrible. Just good. Good lecturer. Good enough test maker with the exception of Midterm 2 which was infamously awful (pretty sure the class average was an F). Test advice is 1) the midterms are short if a problem looks like it will take too long you're 99% chance you're doing it wrong there is some shortcut somewhere you missed go back and find it 2) Put down something, anything, I didn't get 0 credit for a problem all year and believe me there were I knew 0.

Ok, anyways this class is going to suck, but you might as well do it with a solid professor like Harrops.

14.5% - Homework
20% - Midterm 1
20% - Midterm 2
45 % - Final
.5% - Surveys

For context, this was my first in person quarter at UCLA and the first time I had taken timed, in person exams since COVID first hit. Also for context, I breezed through AP Calculus AB/BC in high school and got an A- in MATH 32A.

Starting with the good, I like Professor Harrop-Griffiths because he is very clear when lecturing and is also very, very kind, considerate, and generous. His lectures are engaging and he is helpful when people ask questions. I also think that with the exception of the second midterm he gave this quarter, his exams are pretty fair.

That being said, this class is not easy by nature. I think having a good professor definitely helps but there is no way to avoid the fact that this class is very dense in material and there is A LOT of information/content in it. One thing that I didn't like was that the examples he gave during lecture were always the easiest versions of the problems. You can bet that you will not be seeing questions as easy as those on the exams or even homework.

Summary of the course: first midterm went fine, got an A-. Second midterm was horrible and got a 32%. I was definitely on the lower end of the scores but based off a GroupMe poll a lot of other people also did just as bad or not much better. In response the professor gave a very encouraging message that basically said he will "disregard" our second midterm score when calculating final grades if we perform better on the final. The final was objectively pretty fair but I still got a 71%. In the end, the professor applied a pretty generous curve I think and I ended up with a B in the class which was a lot better than I could have hoped for. Although I'm pretty sure he doesn't normally curve so I'm not sure if he adjusted people's grades individually or applied an overall curve to the class.

I will say that I think a lot of what happened in this class was my own fault. I never went to lecture in person and only watched recordings and as a result I was consistently always at least a week behind. I never did the homework/worksheets and only copied it to submit for the points. Didn't do any practice problems to study for the exams because I was always frantically cramming in the lectures the night before. For that reason, I am extremely grateful for the professor's generosity with final grades and I honestly believe that an A- or A is attainable in the class as long as you don't slack off like I did. Overall, I would take this class with him again. Even though he accidentally made the second midterm way too hard he definitely accounted for it later on and he wasn't purposely trying to make it difficult so I wouldn't hold that against him.

TL;DR: professor is very generous and considerate and if you stay on top of things then an A-/A should be doable.

Harrop-Griffiths is one of if not the best professor I've had so far. Previously I had heard that 32B is one of the hardest lower division math courses, but this professor explains course concepts so clearly that it doesn't feel this way at all. In addition to his clear and well organized lectures, he holds office hours twice a week which I highly recommend you attend. He answers any general or homework questions very thoroughly and clearly (and is also fun to chat with when there are no questions). The homework workload is not too heavy, only about 10-15 problems due every week. The exams are very fair, and everything that we have been tested on he has covered in class. The exam grading system is very fair as well. There are no quizzes for this class, only two 36-hour midterms and one 24-hour final. Overall if you have the chance to take his class I highly highly recommend it!

Harrop-Griffiths was great. I really couldn't have asked for much better in terms of teaching for this course. Despite the tough online environment and the difficulty of the material, Harrop-Griffiths made it relatively smooth.

Lectures: Very clear slides, good detailed explanations, practice problems to keep you engaged. He posts the lecture recordings as well as his worked out slides.

Homework: Weekly assignments mostly from the textbook. Significantly harder than anything covered in lecture, so it is definitely useful to find people to work through or check answers with.

Midterms: Very fair and based on lectures. Marginally easier than homework problems and I felt well prepared with some limited study.

Final Exam: Harder than the midterms for sure. Don't be lured into a false sense of security by your pre-final grade as the final is much tougher. That being said, it is still somewhat fair given what was covered.

Overall, Harrop-Griffiths clearly cared about our learning and is very easily accessible for questions and clarification. He seems very tech-savvy which also helped with the online format. Take him for this class if you can.

I really enjoyed having Harrop-Griffiths for 32B. I was pretty nervous going into 32B since 32A was pretty hard for me (I had Filipazzi for 32A), but Harrop-Griffiths made everything incredibly clear. He made extremely hard topics such as Green's Theorem and Stokes Theorem much less intimidating than they first appear. He used Slack for student questions and replied to almost all questions very promptly.

The grading is 30 percent final, 20 percent each midterm, 25 percent homework, 4.5 percent discussion worksheets, and 0.5 percent surveys. He stressed the importance of instructor evaluations and surveys, and its clear he really values student input as a way for him to enhance his already amazing teaching skills. The homework load was reasonable and a typical homework assignment took me about 5-7 hours to complete. His tests are fair in difficulty and there were no weird/trick questions, unlike 32A.

I thought the midterms were pretty easy (got 100 percent on both) and resemble the sample problems he goes over in lecture. I was a bit nervous about his final since apparently people who took his class in Winter 2019 complained about the difficulty of his final (like the average was a 65 percent). He gave out his Winter 2019 final exam for practice, and the last problem was pretty hard! In contrast, the final I took this quarter was very reasonable in terms of difficulty, harder than midterms but fairly resembled the content in class and the practice finals, with no surprises.

Edit: I got an A in the class :)

Highly recommend Harrop-Griffiths for 32B!

Professor Harrop-Griffiths is probably the best lecturer I've had to date at UCLA, on-par with the legendary Carey Nachenberg. My friends repeatedly joke that I'm the only person they know who actually enjoyed taking 32B, and I must give credit to him for that. His lectures are clear, engaging, and interesting, and I really think the way he structures his class differently than the other professors made it that much easier to follow and understand.

His first two midterms are easy enough, albeit with a bit of a time crunch; his final, though, is quite tricky. It's really comprehensive and expects you to know everything you learned throughout the quarter, and will take quite a bit of problem solving ability to really nail it. I managed to get a B- on the final, getting most of the points on the problems but completely bombing the last one. Honestly, though, if you pay attention in lecture and do the homework, he does a good job of building up the topics on top of what you've already learned.

All in all, I can't recommend Harrop-Griffiths for 32B highly enough. If you get the chance to have him, take it!
