Koffi is an extremely nice and affable professor, but that doesn't make up for how difficult it is to learn the material in his class. He goes over material extremely fast and skips steps all over the place, which makes understanding him through the live lectures almost impossible(I had to watch youtube videos in order to supplement the topics). The worst part isn't his bad handwriting or his really fast pace (even for a summer class) it's the raw amount of hw he assigns. He assigns 15-30 problems per lecture and they tend to be long, complicated, and harder than the tests problems. DO NOT wait to do these if you take him as he grades them for accuracy and they count for 20% of your grade.
Overall I wish he was better at teaching because he is very excited for people to learn and did give a generous extra credit opportunity in the form of a real-world math project, however, this class can be much easier if taken with other professors.

He's a very kind professor and is very helpful, but unfortunately, he isnt really clear or consice with his teaching. His ideas are choppy and all over the place and I could barely follow through with his accent and low-quality microphone ( I took him during the quarantine btw). He holds extra office hours every now and then, but i'd have to rewind the lecture videos every 5 min to fully understand what he's explaining.

For background I took Calc AB in high school and struggled with it, but got a 5 on the (covid-altered) AP test. On the positive side of this course, Koffi does tend to email back quickly, a TA was always responsive on campuswire for questions, and he is overall a very reasonable guy. He will not screw you over just to screw you over, but his perception of your effort is really important. He will be pissed if a lot of people aren't showing up to lecture and if you email him questions he may cross check your email on the list of zoom attendants to see if you go to class. I don't care if people don't find the lectures helpful, at least get your classmates to log on and pretend they're paying attention because you will all have a better time. Like other people mentioned, the homework sets take a long time and some of the problems are graded for accuracy with the rest graded on completion. The first midterm around Week 4 wasn't too bad, the second one on the Friday of Week 9 was a good bit harder for me, and I spent 8 hours on the 24 hour final. The 30 min timed quizzes varied in difficulty but were on the easier side. We pretty much stuffed Taylor/Maclaurin series all into Week 10 (a lot of the material that we learned at the end was on the final) and we had never been tested on it prior. From what I can guess, the type of questions normally asked in-person on tests for a class like this would be easy to look up in all sorts of calculators that exist online, so they had to make the questions non-lookup-able. Do not go into the tests assuming you can just find the answers, you will absolutely have a dirt time. I did not attend his two review sessions but he offered them.

Koffi Enakoutsa is certainly a professor of all time. If you don't have a strong math background, the lectures will be confusing, and even if you do, you'll have to focus extremely hard on what he's saying because of his hard-to-read handwriting and french accent. Luckily, the textbook and practice problems from the assigned homework helped me pick up the concepts pretty well, so if you're someone who can learn well from a textbook, the lectures will feel like a waste of time. The homework, while lengthy and sometimes unnecessary, was a good way to keep me on track with the concepts taught in class.
The two midterms and final were easy because the review sessions he hosts cover the tests' questions, so I highly recommend watching the recordings for the review sessions and using the practice midterms he posts on Canvas. He often reuses and changes the numbers from the practice tests on the actual tests, so make sure to review those. Your TA will also know what questions will be on the midterm and final, and they might host their own review session if they're nice (shoutout ang chen and zachary tu)
The grading weight is pretty standard, with 10% being homework, 5% quizzes, and the other 85% being tests (either 22.5% per midterm and 40% final, or 30% best midterm and 55% final, he takes the better of the two) and it's pretty easy to do well on the quizzes and tests if you follow the stuff above. The homework will be annoying and very long, and he lags behind schedule on teaching, so it'll feel like a lot to learn towards the end. Late homework is accepted for full credit up until the last day of week 10, but I recommend staying on top of it because he will assign a lot at the end anyway. He also posted a homework assignment after the final ??? which a lot of ppl skipped lmao.
Overall: this class wasn't as bad as other ppl say here, but he's not the best teacher and you will have to rely on the textbook, your friends, and your TA. The other reviews glazing him are from himself lmao and the reviews calling him the worst are imo not accurate. If you're looking to have a strong grasp on the concepts, try to take someone else. If you want an easy A, this is honestly not a bad option. If there's no one else left and you're forced to choose this professor, you will be fine, but you will have to put in a lot of effort yourself to understand the concepts well.

Koffi is the goat. Lectures are great, and you learn what you need to be successful on the assessments. There are quizzes which are substantially harder than the tests, but he will sometimes take the best out of each set. The homework can take a long time, but he does not mind if you turn it in late. The tests are generally very fair, and they do not take 6 hours like my other math classes (this was taken during a virtual quarter). Professor does tend to get behind, and in return, there are makeup recordings (about one each week). However, he does have many review sessions for quizzes and tests to keep you prepared. All in all, I would take again and would highly recommend Koffi to anyone.

Koffi is a nice man. However, this was one of the most difficult classes I have ever taken. The material is tough to understand because he explains what he’s about to do, and then solves problems without explaining them step by step. This made it very difficult to understand mathematical concepts that are crucial for the class. In many cases, I would find myself attending lecture and then being lost halfway through the homework. That’s the other issue with the Professor. He assigns many practice problems to help with the basics of what he is teaching, but assigns others that are proof based and almost impossible to solve. He expects his students to understand these problems and ask for help during office hours if they struggle. However, every time I went to discuss the problems with him he would solve them without explaining any of his steps or reasoning. With his exams based off many of these difficult problems, I spent hours and hours working on the tests only to land up with bad grades. The main problem is thus a lack of clarity when lecturing, a massive and unnecessary homework course-load, and difficult and almost impossible exams that are much more difficult than anything done during class. Until these problems are fixed I cannot, in good conscience, recommend Koffi as a professor.

Koffi is pretty good. He is a very caring and humorous professor who obviously cares a lot about teaching. However, his lectures are sometimes a bit dull and not that helpful. I can't really say much about the lectures since I stopped going to them ever since week 2 (I think). Reading the book is essentially how I learned in this class. There are free versions of this book online, and Koffi's tests are very very easy (24 hrs during COVID-19, but idk will that change or not). The homework is way more difficult than the actual tests themselves, and overall it is not hard to get an A in Koffi's class. To summarize: easy A and read the book.

Koffi is a really great guy and a really nice professor overall! He is very accommodating and tolerant of late work, homework questions, or just general confusion about the material. People mentioned that he has an accent, but I personally didn't think it was a learning impediment in any way. The tests that he writes are fairly straightforward and easy so you don't need to worry too much about them, especially with 24 hour test policy that the math department has for COVID. He does his best to ensure that the class that he teaches isn't a horrible experience for us, and he puts in a lot of his own personal time (3 office hours, being available all day on zoom for test days, review sessions outside of class led by him) to ensure that there are recourses. If you have the option, I would say take him!

Koffi is a very kind and approachable professor who is passionate about teaching. However, this was his first quarter at UCLA, and I think he had a difficult time adjusting to the pace of the quarter system having previously taught only on the semester system. At the beginning of the course, he spent a lot of time on concepts that didn't really need that much elaboration, resulting in him not finishing on time and assigning hours of prerecorded lectures for us to watch. He realized this wasn't a sustainable approach, though, and stopped doing this, seemingly learning to manage instructional time better in the coming weeks. Homework was challenging and long, and it's very easy to lose points, so I highly suggest comparing answers with classmates or verifying them online. He gave two midterms and a final, all of which were pretty fair, as well as timed quizzes which counted as 10% of your midterm grade.

He is very approachable during office hours and also hosted a few optional test review sessions. He doesn't always explain things in the clearest way during lectures, so office hours are very helpful if you didn't understand the material that well. Lastly, he does have a thick accent, but I don't really think it made him hard to understand. Some of my criticisms of Koffi are a result of his transition to the quarter system rather than his actual teaching ability, so keep that in mind. I'm sure that he will improve over time.

There is one homework assignment per week, he extends deadline till the end of the quarter for many of them. The homework assignments get pretty hard since he includes problems from the back of the sections, but they're doable if you go to office hours or find a study group. Find a good study group you can compare answers with because around 80% of the homework assignment is few questions graded on accuracy and rest is for completion.
Midterms tend to be easier than homework. The questions are similar to his review sessions so make sure to attend those and understand how to do those problems fully. Finals are similar, but the questions are somewhat harder. Make sure to not silly errors on tests like me because those cost a lot of points.
He uploads pre-recorded lectures online and also some in-class recordings. He also uploads review session recordings. Make sure to watch them.
Sometimes, his lectures can be hard to understand. Make sure to read the book then.
The content isn't easy, but it's possible to get an A-/A if you do all the homework and start studying for midterms/finals a week in advance. I would recommend this.
