Taking this as an online course was really not a problem with this professor. He was very organized along with his TAs as they had everything planned out from the beginning and lecture formats were consistent and easy to follow. They also record everything that goes on and offer plenty of office hours. The professor has a slight accent but it was still easy to understand. The class is structured so that the lectures will cover most of the info and if there is uncertainty for homework problems one can read examples in the textbook. He assigns one homework assignment per week which takes about 2-4 hours to do. Including lectures and discussions, expect 6-10 hours each week dedicated to this class if you want to pass with a good grade. Homework problems come directly from the textbook and most are just good practice for the concepts covered in lectures. Some questions come from the challenge section of the textbook which is pretty hard but manageable if you ask during discussion sections. But don't let those questions discourage you because they usually do not matter for the quizzes, midterms, and final. Homework is checked for completeness as well as correctness but he only picks 3 problems to grade. He also drops 2 of the lowest homework grades at the end of the quarter so its not hard to get a perfect score on homework. Make sure to check your answers with the back of the book or slader so that you don't get docked. There are 3 quizzes total for the quarter and they are timed for 30 minutes but as long as you understand the concepts they are pretty easy. The midterms both had around 4-5 questions and of those questions there were usually 1 or 2 really tricky questions. He gives a 24 hour period to do the midterms (meaning you can spend 24 hours if you wanted) but even with that I was only able to get B's on the midterm. 1 question can really screw you up! I also usually spent the whole day on the midterm (excluding breaks and all it probably took around 4 hours to complete). Biggest advice on the midterms is to make sure you study even though it is a 24 hour period and open note. However, the final was definitely easier than the midterm considering I got a 98% on it and the same format goes for the final. Just make sure to also study for this one even though its 24 hours! He also ended up lowering the cut offs for the course which was really nice because I was at a borderline A- which he bumped up to an A. He seems a bit cold when he responds but he gets straight to the point. Email him if you have questions because he usually responds within minutes! Overall, take this teacher if you want an easy to follow class that as long as you put in the effort is not a hard A.

Overall: Filipazzi is a great teacher and lecturer who is good at explaining concepts and willing to take the extra time to help his students understand. However, he is not lenient in terms of grading or assignments whatsoever. For example, he wouldn't drop a quiz even though other professors dropped one or even two, he won't take late homework, not even for partial credit, etc. This isn't necessarily a bad thing, he just has expectations and won't budge on them.
Homework: due every Friday, drops 2. Some weeks' homework were significantly longer than others, but I'd say they generally took me about 3-5 hours.
Quizzes: 30 minute time limit and very conceptual. There is very small margin of error in terms of time and mistakes in general since they're only out of 10 points.
Exams: 24 hours, but VERY challenging. Midterms were supposed to take 50 minutes, but most people ended up taking 10+ hours. They are definitely way longer and harder than they need to be, which I have confirmed after seeing what exams are like in Math 32B. Many questions will cover topics learned in class, but with weird exceptions and other topics he did not cover in class. Additionally, the grading is super harsh. All I can say is SHOW ALL YOUR WORK because missing one small thing can make you lose half the points even if your answer is correct.

Filipazzi is a great option when taking this course, at least in an online format. I feel like some of his negative ratings are a result of the class just being hard, which is not his fault and can't really be avoided if you don't want to screw yourself over for future classes. His lectures aren't anything innovative but are very concise and helpful. I primarily learned the content from them and only referred to the textbook for particular examples. His homework load is relatively high but is expected in a math course and pertained to the lecture and test material. At least online, I would consider the difficulty level of his exams appropriate for the course material, which is difficult. They were a mix of conceptual and numerical, and I would not expect any free points from plug and chug questions. Overall, Filipazzi is a good choice for this class if you want to get the material under your belt for future classes and come out with a pretty good grade as well. If you really just want an easy A, there may be better choices. Also, his accent is awesome.

Professor Filipazzi was really hard for me. I spent a lot of time every week (10+ hours) trying to finish all of the homework he assigned while understanding the topic. I read all of the assigned textbook sections, and went to his lectures live, but I still struggled a lot during the 24 hour midterms. I guess people were doing really well with it, but I found the questions to be so so difficult and spent all 24 hours on the midterms, to still get a C- on both of my midterms. Luckily, I somehow did well on the final exam so I did way better in the class than I expected, but the class was still super challenging for me. His lectures were actually really clear and his handwriting is nice. For some reason the way he writes his f's translated into my handwriting, so now I write in all print with cursive f's lol. Anyways, he's alright, just a difficult class.

Professor Filipazzi is one of the best professors I have had at UCLA. His lectures are super engaging and organized, and he is great at answering questions during office hours. The homework assignments are incredibly difficult and time-consuming but give you a really good handle on the material (and some of the problems are even included word-for-word in exams). I highly recommend taking this class with this professor.
