Fall 2017 - NOTE: ACTUAL CLASS TAKEN: Ch ENGR 101A Professor Cohen is literally the WORST professor or teacher I have ever had in elementary school, middle school, high school, and here at UCLA. He is a snobby bitch, and when you ask a question he just answers with a rhetorical; it’s like, “dude, if I knew the answer I wouldn’t ask.” I asked him a question on a test and he just answers with a question and a smirk, and I’m sitting there thinking “fuck you, you just wasted my time on the exam.” He should not be allowed to teach. His handwriting is impossible to read, I can’t tell if it is a rho, a P, or an e half the time. And he goes so fast, writing so sloppily I can’t even comprehend what’s going on in class. He is also the most boring professor ever. I have to eat a whole bag of candy to get a sugar rush to stay awake. Also, he does not understand what a university holiday is. Twice, he tried to make a homework due in person on a university holiday. It is disrespectful that he is emailing out an assignment on Thanksgiving holiday. Also, stop bitching about us writing on the back of the paper on homework. Your syllabus literally says that the homework is 3-5 problems yet every homework is 6-7 problems, and one even had 8. Also, buy a clue, the entire class has class in the same fucking room from 12-4. You are a jackass who won’t let us eat to pay attention. You have 2 hours while we are in class to eat, so stop complaining. Nobody likes you. In summary, screw you Cohen, I hope I never have to see you ever again.
Fall 2020 - I think old reviews for Dr. Cohen don't paint a fair picture. He really is a nice guy who cares about students and wants them to succeed. He does his absolute best to make himself available, plenty of office hours, giving out his cell#, etc. Overall, this class can be a LOT of work for a ChemE elective. Don't let it being an elective fool you. Expect the following: biweekly homework, exams, weekly progress reports, presentations, final projects, etc. Easily more work than a standard ChemE class, more comparable to a lab. While it's a large amount of work, the course is pretty interesting/unique, and in the end he grades very generously.
