Reviews of professor Jonathan Cohen

Rating: 2.0/5, difficulty: 5.0/5
I had to learn the hardest math class for my engineering career and having Cohen as my professor did not help. His quizzes to force participation in his lectures are well-intended but I was clearly lost most of the time. His homework is strenuously long and often took days to finish. The take-home tests were nice but the material was painful.

HW doesn't even resemble the tests. Doesn't post lectures online and there is no textbook, so must attend class. Class was curved

Dr. Cohen was a lot better professor than the other reviews claim. His homework was difficult and helped you learn the theory behind the material, but the lecture problems were very similar to the test. The biggest difficulty was that the tests were very long and hard to finish. The tests and the class as a whole was curved, so an 87 was an A.

This class is lecture reliant where missing a lecture means you're a whole content behind. Quizzes are always every week and he is generous enough to only take the top 10 quizzes of 14 quizzes. The exams are hard because it's super time consuming and usually the average is an F. I studied super hard on my own to pass this class. PS Jon is nice!

Dr. Cohen was a very tough professor. His homework would be extremely difficult and the math center wouldn't even know how to solve the problems. Even worse, he would often take forever or don't know how to solve the problems. Though, the good side is his exams are take home and a good portion of your grade are his weekly homework.

Avoid. Nothing resemble anything in this class. Quizzes are simple but Homework problems are extremely hard. His exams are very long and tricky. Often brings in new type of problems in exam.

AVOID. His homework was difficult and did not resemble his tests or quizzes. His test were hard and there were weekly quizzes. He will meet with you outside of class but not helpful.

If Mathematics was a video game, Cohen would be the final boss.

Under no circumstances would I recommend anyone take this class. This dude teaches straight from the textbook (which is a terrible textbook) and doesn't realize or doesn't care that the whole class isn't following the lectures. Weekly quizzes, homework is covers nothing that is covered in class, and the tests are much harder than what's taught.

He had to curve our class at the end of the year and would blame the students at a failed exam. He would choose hard problems on the homework and quizzes and Exams, which made it feel like a war on mathematics. I would not recommend at all costs
