All MATH535 lecture material comes from an online textbook written by Dr. Roch himself. Attendance is measured using TopHat (full credit for attending at least half the classes). He's a pretty good lecturer, focusing on the most important topics and leaving time for questions. If you attend class, scoring well on the exams isn't too hard.Rate My Professors ↗

What students say
Original student reviews · all captured dates
I don't understand these reviews, Sebastien is amazing at teaching. He has a deep understanding of the material, gives easy exams, helpful outside of class.Rate My Professors ↗
A great way instructing things and letting student know Math is not the thing. Super "rigorous" and quite confusing, and so could possibly make the topic complicated to a level that is not appropriate for this level of class.Rate My Professors ↗
He is not good at teaching but he is very willing to help and his lecture notes are very good for self-learning. So it's okay to take class with him if you are a good self-learner.Rate My Professors ↗
I don't know what Prof. Roch is talking about, he can introduce a hundred theorems with little to no explanations, let alone give examples. HW is also challenging, you should take care yourself and learn by yourself.Rate My Professors ↗
Math 632 is a hard course as it. Although Roch taught the class clearly he sometimes went fast. The lectures are proof heavy while the homeworks and tests are not. There are no solutions to homeoworks posted except for the quiz questions based on the homeowork. The exams are intended to be very difficult and require you to think beyond homework.Rate My Professors ↗
