Great lecture and nice dude.

Nice and funny guy and very lax on due dates, however, terrible lecturer.

I stopped going to lectures after week 1. A mask combined with his accent and a poor mic setup meant it was almost impossible to understand what he was saying in class. On the bright side, he recognized that and so he started posting youtube videos of lecture content the day before (where it was much easier to understand). He held review sessions before exams, and the exams had almost the exact same questions as those sessions (with different numbers ofc). Both were based on homework questions so you don’t really need to attend review sessions if you know how to do the homework. The only thing annoying is that he loves assigning the “further insights and challenges” questions on the homework, which sometimes took me hours to figure out and other times I just gave up.

do not take this instructor's class if you have a hard time understanding accents. dude seems really nice and he has cool funky outfits but i could not for the life of me figure out what he was saying because of his heavy accent which was aggravated by also wearing a mask. In the online lectures without the mask I could understand slightly better but it was just really discouraging and annoying and made me not go to lecture or office hours

Hilarious dude, very helpful and considerate, I recommend for an easy A. The professor's accent is extremely strong so it can be very challenging to understand because he is also quiet. His homework assignments are long and tedious and can be somewhat hard, but they are infinitely harder than anything you will see on the tests (plus the hw's are graded easily too). The tests are very very easy and the review sessions he holds before each one will give up to half of the questions on the test away. Thank you Professor Koffi!

A great professor. The homework assignments are very helpful to understand the topics taught during the class. The professor is vey knowledgeable of the topics. Overall, I recommend him for Math 32a.

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.
