Horrible class. By far the worst class Ive ever taken anywhere
* Ridiculous amount of hw, totally unrelated to lecture content
* Disorganized, unclear lectures. Difficult to know what section we are on
* Unreasonably fast-paced
* Indecipherable handwriting (not his fault but accent tbh)
Don't be fooled by his fake reviews lol, you dont need to be sherlock holmes to decipher which ones are fabricated. Pathetic behavior if you ask me--just screams a fragile ego. Honestly I have no idea how this guy is employed by UCLA. He gives off a good facade of a caring prof but this class has caused me so much unnecessary stress. Avoid at all costs

The worst professor ever. Made lots of typos in his lectures. Couldn't solve his own homework question. Gave fake proofs during office hours. Homework is totally unrelated to lecture.

I don't think this class is as bad as some of the other comments suggest.
The exam content is entirely identical to what was covered in the review section (it's like they gave us practice exams) and they also provided an Improvement Test.
I've noticed a lot of people complaining about having too much homework. In fact, This class simply compresses the normal 10-week workload into 6 weeks (with frequent extensions on due dates and drops the three lowest grades.
As for the professor's handwriting, I don't think it's a big issue. In fact, his notes are relatively neat, with only some variations in the way he writes certain letters. Once you get used to his handwriting, his notes are still easy to read.

My experience in Professor Koffi's class has been quite disappointing and frustrating. The topics covered were needlessly complex and convoluted methods/proofs and HW load is ridiculous.

The testing format added further stress with the first test being 50 minutes of tough questions, leaving little time to think critically.
However, the second midterm was slightly more reasonable in difficulty.

The final was completely comprehensive on all of the chapters, with no formula sheet as we received in the 2nd midterm, and the last topic was covered 2 days before the final. I hope that in the future, Professor Koffi will take student feedback seriously instead of writing fake reviews for himself

-The quality of the posted notes added to the struggle as they were disorganized, messy, and often illegible.
-Although I understand this isn't his fault, Professor Koffi's thick accent proved to be a significant barrier.

Logistics:
10% Homework (2 are dropped)
20% Midterm 1
20% Midterm 2
50% Final
No alternative scheme available.

Homework's are tedious and he basically assigned 1 homework per lecture, and most problems do not prepare you for exams. Luckily, a majority of them were graded on completion.

Midterm problems are similar to the ones in the review session that he posts. He fortunately gives you the topics that are going to be on the midterms and final so you don't waste your time focusing on things that aren't going to be on it. He made the final open book, but of course that increased the difficulty of the exam. The final was also extremely long compared to past finals, so an 1hr and 50 min did not seem like a sufficient amount of time to finish.

I would only recommend taking this class during the summer if it is your only one so you can dedicate more time to it, but in reality this class caused more stressful moments than happier ones.

Don't take him. I was wrong thinking I could manage this after taking his 32A in the first quarter of my freshmen year. I thought his accent was tolerable; at some point in upper div math you don't even have the mental capacity to translate someone's English in your mind. Second, I don't know how the heck his handwritten notes got worse. I prefer someone's elementary school's writing versus some cursive when I am reading math. Third, there are two midterms, in a SUMMER session, and there is only one grading scheme. Fourth, he changed the exam to open-book in the last 16-hours before the final, after SET surveys are due, after I reviewed thinking it was closed-book. Yep, no. I am going the other way next time I see him listed as one of my professors.

Update: the Final was horrendous. Each of the 6 questions had at least 3-4 subsections to it. The calculations are impossible to be done in a 1hr50min test, even with a calculator (simply typing the matrices takes up 20min).

This is probably the worst class I have ever taken at UCLA. He is extremely unprofessional and not a good instructor. I attempted to go to his office hours (he doesn't really advertise these (lol) so you have to ask him about it) and he was seriously bothered that I went and asked for help XD. Go to one of his lectures in the quarter prior to when you are taking him and you'll understand what I mean immediately. im sure he is very qualified as he has a position here but he is seriously not a good professor in my opinion.

The grade distribution seems enticing but it isn't like that anymore for him and you wont learn a thing, unless it is a class like 170E where you can use the textbook. Take someone else.

useless stuck-up unaccommodating professor

Clever and very accommodating Professor!
