Besides that you also have to read the textbook. He knows the material well but has no idea how to teach. Get ready to learn from the TAs(if you are lucky) and the textbook.",

Very easy to learn the material. 10/10 recommend writing down any homework problems cause it should be very similar to what is on exams. Lot of work but worth it.",

He might be better at teaching high level math courses, but if youre taking a gen ed class Id avoid this professor.",

There were weekly open note mini tests, so it's important that you have good notes. Online testing means small mistakes can tank your grade, even if your work is good.",
