To put it plainly, if you take him you'll have a homework each week (no exception) with on average 25 exercises but it can go as much as 40, which takes on average 7 to 15 hours. It's a heavy workload, especially when you have him in 2 classes (would not recommend at all, I had 60 to 80 exercises a week just with these 2 classes, it was a nightmare).
He doesn't drop any grade (not flexible at all on that), but you can give back all homework until the last day of the last week.
For the test, it was covid so we had 24 hours, it was honestly not that bad compared to the homework and the course. Everything was doable, but clearly not in 50 minutes as he said, more in 5 to 6 hours. But doable, not impossible.

Do not take this class

easy exams (extremely similar to what he shows in review sessions, often the same or with changed numbers), lots of homework including several proofs (however he lets you turn it in as late as the end of the quarter), unclear lectures with messy handwriting (only worth going to for fun because koffi is a nice wholesome person)

pros:
- very easy exams
- can turn in homework at end of quarter
- cool professor

cons:
- poor lectures
- lots of homework
- poorly paced class (you will definitely not be on schedule don't bother looking at the class calendar)

Koffi is a very nice professor. Even though sometimes I cannot understand what he said during the class, it doesnt quite matter lol. His lecture slides are VERY USEFUL. If you dont have time to attend his lecture, make sure you go over his lecture slides and understand every SINGLE EXAMPLE QUESION so that you can perform well in HW and the exam.

There are some tricky questions in the exam in which the wording is weird. You might lose some points on that but the other calculate-based questions are easy. Be sure to get clear with basic concepts. The workload of this class is not that light but not that heavy as well, you can manage that within a day or two for the weekly homework.

I have never taken a class with students feeling so divided over the quality of a professor. People often joked about how all the positive bruinwalk reviews of Koffi are him with a bunch of fake accounts, and... Koffi is the exact kind of man who would do that. He is by far the worst professor I have had the misfortune of taking at UCLA, and truly should not be teaching. You will learn more if you skip class, don't even try reading his lecture notes (which are years old and all in cursive) and just read the textbook like its the religious text of your choice.
.

This brings up another issue: this class was so incredibly unorganized. Since week 1, Koffi was constantly 3-6 lectures behind schedule. The problem was that discussion sections didn’t take this into account, so the TA’s were always ahead of schedule. We were learning about TNB frames in section without even knowing cross product in lecture. Weekly homework also covered material from 1-2 weeks ago, which just completely threw off my groove. When I asked Koffi if he could post the upcoming homework earlier, he refused and responded with a rude email.
.

We all know Koffi is a poor lecturer. And if that was the only thing bad about him, he wouldn't be that bad. He actively fostered an unhealthy learning environment, taking the time out of each lecture to call the students on zoom lazy (literally for minutes on end). Now, I always attended lecture in person, but the fact that he wasted our time when he was already 2 weeks behind was… frustrating. He also went on tirades during office hours and review sessions about literally anything other than math. Oh, he also accidentally posted his response to being rejected from a job he applied for in the zoom chat. So that shows you where his priorities lay. Not with the students.
.

His midterms are slightly challenging, but nothing unexpected. The final was significantly more difficult, with lots of conceptual material asking you to prove whether conditions are true/false. This is content that he never mentioned in review sessions, and explicitly said he would not be including on the final. Though the homework (taken directly from the book) always included the challenge questions at the end of each chapter. Homework assignments took very long (because they had lots of challenge questions).
.

Koffi crammed a weeks worth of lecture material into the weekend before finals week, and assigned 2 or 3 weeks worth of homework during finals week. And held lecture during finals week. He also held virtual lecture on a federal holiday. This man expects you to treat this class like it is the only class you are taking.
.

Whenever I asked him a question or emailed him, he was extremely combative and outright rude. I’m not exaggerating when I say I felt like Koffi was low-key being a bully. I was having a conversation with him via email regarding grades, and after initially addressing him in the first email with “Dear Professor Enakoutsa, I hope this email finds you well…” I followed standard email etiquette and in my second email to him in the chain, continued the conversation without readdressing him again. Well, he did NOT like that and said: “Hi: Have you forgotten the format of the email? Koffi E”. All because I did not begin every email with “Dear Professor Enakoutsa”… I felt like he was just enjoying his power trip, which is such a shame.
.

Overall, Professor Koffi Enakoutsa (as that is how he likes to be addressed) near single-handedly made me change majors. Professors in the math department don’t need to try and make math enjoyable, but they shouldn’t actively make the process of learning math dreadful. And that is where Enakoutsa fails.

No human being with a functioning brain should voluntarily take this class. Unless you have no other lectures open and your existence on planet earth was threatened if you didn't take this class, there should be NO reason to be taking ANY class with this guy. You can't understand what he's saying. You can't understand his handwriting and notes. He's behind on material but expects you to catch up on your own and gives BRUTALLY EXCRUCIATING questions that are ridiculously nonsense on the final to intentionally screw you up. Imagine learning an entirely new chapter (5 days before the final) because he told you to, and then getting the hardest question of that chapter on the final. Also, he doesn't know how to efficiently operate a keyboard, because 90% of the time it's impossible to even understand what he writes in his emails due to typos and outright NONSENSE sentences. If you struggle in this class and send him an email to ask a question or submit a regrade request, you will get the most morally corrupt, vile, degenerate, inhumane response known to man. If you want to be a functioning human being who contributes meaningfully to the betterment of society and the world, DO NOT take ANY class with this guy.

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.

Koffi is overall a fantastic professor. The tests are very very straightforward if you did the first half of the back problems in the textbook. His exam review sessions are very helpful and you can score 75% without studying if you just attend them. Sometimes his lecture becomes big and hard but his prerecorded videos are small and soft. It is easy to lose marks on his midterms due to silly errors because they consist of only 4 qs but 25 marks each holy damn Barack Hussein Obama! He is also very cute and unpredictable so even if you do not understand his material because of his accent, you will have so much fun in his class. He does not look down upon pets in class since he loves animals. I would definitely retake this professor if it was possible. If any of you have a tattoo however, then I suggest you find a different professor. Good Luck everyone.

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.

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.
