Rating: 1.0/5, difficulty: 5.0/5
He yells at students all the time. He deosn't try to put himself in the student's shoes. When I asked something about the lecture, he made me feel belittle for not understanding it

Rating: 2.0/5, difficulty: 4.0/5
Lectures are very hard to understand, follow, and often have mistakes as he moves at a very fast pace. Difficult to learn anything from his lectures, and if they were not recorded it would have been a much tougher class. Tests and assignments are similar to lecture examples.

Rating: 1.0/5, difficulty: 3.0/5
Like other pp mentioned below, the professor often showed aggressive words to students, making us feel awkward in class. When there was something unclear about the lecture, I could not ask him because he will say "How do you not know about this"
I also agree with "Be wary of 5.0 ratings."
