I am not exaggerating when I say he is by far the worst professor I have ever had in 4 years of college, and probably one of the worst humans I have ever had to interact with in my entire life. There are hard professors sure, but he is more of a billeting jerk who tries to make students feel stupid compared to him.

He's very stimulating in lecture, and frequently asks the audience questions which enhances attention and learning (in my opinion). His homeworks can be quite long, and your research skills shouldwill be definitely sharpened, but the questions are very interesting. Tests are pretty fair.

The contents aren't too difficult, but you should expect devoting a lot of time in homework assignments, which is like a small project each. Attend lectures definitely saves your time.

Dr. Kahn's classes are VERY HARD but his material is always interesting and he constantly pushes students towards harder concepts. If you really try and work hard you will succeed. Please go to his office hours if you need help. He is very kind and supportive, even if he may seem intimidating. DO NOT CHEAT OR SLACK OFF IN HIS CLASS
