Grading Scale:
discussion wksts: 5%
homework: 10%
midterms: 22.5% each (or 30% of best)
final: 40% (or 55%)
*better of the two options is chosen

Textbook:
Textbooks are only used for homework problems, but can be useful for practice or going over lessons, as lectures are often based off of them.

Exams:
Go to the review sessions. They tell you everything you need for the midterms. The final was much harder than the midterms, so do not put as much trust into the review sessions.

Grading:
The tests (I think) are graded by TAs but regrades are graded by Koffi. He is very stubborn and will more than likely not change any grades, even if you try to explain yourself.

Homework & Discussion Worksheets
For homework, he assigns a ton of problems but only grades 3-5 per assignment, and they are usually one of the first ones. Do not stress too much on the harder proofs at the end; they are never graded. There will be due dates for homework and discussion worksheets, but he gives you up until the end of the quarter to turn them in for full credit. Just email him to open up the submissions. Discussion worksheets are just problems from the textbook, and they do not have to be completed—a submission of what you finished within discussion gives you full credit.

Lectures:
Lectures are pre-recorded so that students can watch them before class. The classes themselves are also recorded. Koffi has an accent, but as long as you sit in the front or have your volume up on zoom, it is not too much of an issue. I found watching the lectures beforehand and following along with the textbook helpful to understanding the in class lectures. Koffi encourages questions which is nice, though he rarely understands the questions being asked. He oftentimes answers questions before people are done asking or just answers questions that he hears/wants to hear instead of the ones being asked. He can also be stubborn/blinded to corrections and it can be a little frustrating.

Professor:
Overall, Koffi is a very kind and funny professor. However, he spends a lot of class time with shady rants about students who go to the online lectures instead of in person (though he tries his best to express his understanding of the pandemic and it’s effects on learning). As said earlier, he is also stubborn with regrades and difficult with questions. Despite all that, he is a genuinely caring professor who wants his students to pass.

TAs:
I had Steven Troung as my TA. He’s a great TA! He’s been working with Koffi for a while now and is a great teacher. I had the Tuesday discussion which meant the worksheets oftentimes had material from lectures we haven’t had yet. However, Steven was great in giving mini lessons so that we could get them done. If you want these mini lessons that are easy to follow before going to the more heavy lectures, I recommend getting a Tuesday discussion. If you want to be able to do the worksheets after the lectures, choose Thursday.

First math class I've taken at UCLA and I hope they get better. In general he seems like a very nice person and he cares a lot about his students, but... I'm sorry he's just a bad teacher for me.

His lectures are impenetrable. A lot of factors combine towards this (heavy accent, cool but hard to read handwriting, makes a lot of mistakes constantly and sometimes just comes out with straight up the wrong answer when nobody corrects him), but alone those wouldn't be that big a deal. Primarily the issue lies in the organization of his lectures. Half the time I don't know what topic we're on. I ended up just self-studying and taking notes from the book while sitting in lectures. He doesn't use slides in lectures- it's just him and an iPad, but he provides slides from some other source with the book.

Tests are uncurved, and a lot of people say they are really easy, which I agree with *most* of the time. However, IDK if it was just me, but the grading was way too hard and I got destroyed for minuscule errors. I'm generally not a perfectionist with math and I make little mistakes, but when those do slip through I got dunked on for them.

Review sessions are supposedly the key to doing well on the tests, and I attended in full, but it was literally just 4 hours of him mumbling to himself, making mistakes, etc. It was just really hard to figure out what topic he was on, and he didn't explain anything.

Basically, some of my friends came out of his class with an A because they were better able to adapt to his teaching style than me. He just didn't click with me and that's ok, I passed at least LOL. His class works with some people, not with others, so before you take his class just take that into consideration.

Koffi is a great professor. His review sessions are exactly like the tests, which is fantastic. Anybody saying that he is hard to understand is completely ridiculous -- he has an accent, but it does not at all affect understanding of the material or what he is saying. The amount of homework problems is a bit much, but they're not too bad. I chose to take 32B with Koffi because I loved this class with him so much.

Welcome to another quarter where the lazy, uneducated, and illiterate students who think they are entitled to pass classes without putting an effort become writers on a blog very tolerant to insults limit racists. The professor is African. Maybe that what bother you given the amount of ignorance and stupidity people vehiculate on that part of the earth at the age (oh Please!!!!!!!!!) of INTERNET! He has an accent because his first language is not English. Stop this stupidity! His handwriting is the most beautiful I have ever seen. Please stop the stupidity and go back to your textbooks and work. You will have a lot to gain rather than complaining. Keep writing the crap things about hime here and yes you are on a way to a great scholar success.

This review is meant for either people who are slightly above or average knowledge in math. It's my second year here at UCLA, and looking back this is easily the worst class I have ever taken. I consider myself a good student in Math, and Koffi made the topics so much harder than they actually needed to be. First, it was because he has a very thick accent and a cursive-like handwriting that makes the material difficult to understand. Secondly, he drags on and on about pointless examples, but when you try and do the homework about 25% is actually related to what we did in class. The other 75% are challenge problems that are significantly harder than anything in the textbook. The worst part is the tests and midterms are similar to the challenge problems and contain multiple steps. They are meant to be taken in 50 minutes, but most students took a minimum of 8 hours for the midterms, and some students I know took 20 hours on the "3 hour final" because they had to learn so much new PHD level material. These are unlike anything that we practice in class or on the homework, and if you have a bad understanding of the textbook you would definitely fail. Whenever I went to his office hours it was a total shitshow, he does parts of the problems that you don't understand and just expects you to know how to do the rest on your own. He might be a nice guy, but he expects his students in the class to have a level of math knowledge already comparable to like a grad student.

LOVED Professor Koffi. Prepare to go to office hours frequently as his problem sets are relatively difficult compared to what you learn in class, but once you do the tests are a breeze. This was one of my favorite classes and Professor Koffi is an absolute sweetheart who cares so much about her students. Absolutely recommend taking a class with him!

A combination of bad handwriting and an accent makes it slightly difficult to keep up. If you zone out for a minute you are done for and might as well leave and just watch the recording later. He is super nice though and a very genuinely caring teacher who remembers peoples' names and cares that we understand things well. He was accommodating of me not being able to come to live lectures on days I had work even though he asked us to come to live lecture. He did assign over 100 problems a week (lots of which were the challenge problems which would take 10x as long) but that might be because it was summer (6 weeks).

I took Multivariable Calculus with Professor Koffi, and the class was a joy. The course required effort to be put in, watching the lectures and doing homework ahead of time. Koffi gave lots of great online resources and was always available to help answer questions. Be ready for content-rich tests.

Koffi is very intelligent and caring, but so intelligent sometimes it is hard to understand what he is saying. COVID online classes were easier because they were recorded and you could rewind. Multivariable Cal is hard but koffi made it very easy. He genuinely cares about students and multi. Will take him again if I have to.

Great lecturer. Engaging course. Homework assignments were heavy but I learned a lot from this class. Will take him again.
