MATH 535
Quality 1/5Difficulty 4/5
For Math345, professor speaks way too fast for anyone to fully understand. He doesn't explain well and is in his own head. Not a good teacher.

MATH 535
Quality 4/5Difficulty 3/5
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.

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.

MATH 535
Quality 1/5Difficulty 5/5
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.

Quality 3/5Difficulty 2/5
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.

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.
