Prof Crombecque is extremely helpful. His lectures are clear and straightforward. If you work in hard you will surly see results. He holds plenty of office hours so there's no excuse for not getting help. The material gets complicated but he makes is understandable for those who are not math happy.

Professor Crombecque is a very nice man and a decent professor, but there are a few fatal flaws with this math course. He assigns around 25-30 problems of homework a week that are graded very harshly and therefore he loses the fun side math of.

If you haven't noticed, a ton of the math teachers at USC are pretty bad. Crombecque is probably one of the best ones for many reasons: He explains things very thoroughly and is patient with his students. That being said, he assigns crazy amounts of homework and only grades a couple of the problems. Tests are reasonable if you do example problems.

It's not even that hard, but as someone already mentioned on here, he grades insanely harshly. Like nothing I've ever seen before. It's pretty criminal if you ask me. If you want to learn the material (which you should) I'd go buy Hammock's Book of Proof and go through it on your own. You'll learn the material without killing your GPA, a win-win.

The class wasn't hard. The material wasn't hard. The professor made linear algebra hard for no reason. His tests are unreasonably long, his grading is just absurd (if you make small calculation mistakes here and there, your grade will suffer a lot). He is often late to his own class, and he extends the lecture to 10 min after. Really frustrating.

Crombeque almost killed my love for math. His tests are completely unreasonable. The problems aren't difficult, the issue is with an absurd amount of problems. This ended up making it impossible to do well in the course unless you've been in a high ranking math team. Also never talks about grading scale, so it's impossible to judge where you are.

WORST PROFESSOR. His test were incredibly long so u cant ever finish. If you make one minor algebra mistake youre completely screwed. Hes also a very rude person. He answers questions with a lot of attitude and is very sarcastic. Also he wont tell us anything about the grading scale so we have no idea what grade we will get. Do not take him.

499 was my favorite class this semester! Professor Crombecque is great at lecturing and is super funny. It's a small class, so you get to know your classmates--I felt comfortable sharing how I did proofs, even when I got them wrong. I feel ready for 425A after this. Tests are long and you'll definitely feel short on time.

I've tried all MATH225 professors during the first week, Crombecque is truly the best lecturer among them. However, he gives REALLY LONG exams and grades them pretty toughly. You have to understand the material VERY WELL to get a decent grade. It's challenging and it takes a huge amount of time before exams but not impossible to do well.

I wouldn't recommend taking him for MATH225. Not because he is a bad professor, his lectures are actually pretty good. It's just that his exams are sooooo long. Around 5 questions in an hour, each questions with 3-5 subparts. He purposefully does that for Zoom so ppl don't cheat, he's probably better in person.

Prof. Crombecque is just a solid choice for linear algebra. His lectures are good and crystal clear. But tests are somewhat hard and long. My friends told me it's probably easier to get a good grade with other profs. But you really learn from Crombecque and he just provides great intuitions. He is a little bit rude though.

He often belittles students who either don't get the right answer or don't meet his standards.

What a disaster. Tests are just about how well you can speedrun a problem set. Holds tons of office hours, which he uses as opportunities to berate students 1-on-1. Feels the need to frequently remind us that he has a Ph.D. and has better things to do than answer students' questions. Final exam is 35% of grade. Test avgs as low as 67, no curve.

M126 w/ Crombecque was certainly hard, but the professor's lectures definitely help to explain hard concepts better than the textbook. Longer assignments are given weekly with a bunch of small, pretty-easy quizzes to boost your grade a bit. Though the lectures are great, exams are still a large time crunch.

A decent choice for a MATH-126 course. Grade depends mostly on midterms and finals (20%, 15%, and 35%) but there are no "trick questions" and it's clear what you need to do + HWs and grades cushion you (he drops couple worst quizzes/hw). Doesn't really show a lot of leniency if it seems like you didn't try. Lots of HW--try to form a study group!
