Reviews of professor Insu Yi

Rating: 5.0/5, difficulty: 5.0/5
Yi is very interesting. Not the kind of professor I'm used to. Very relaxed when it comes to formalities, but the tests are very difficult. You need to study.

Theory is the only thing he goes over in class. He never shows true examples and when you ask him a question he sometime says, "I don't know." If you don't understand something in lab he will not help you. He will put in a place holder grade and then eventually grade quizzes. He offers redos, but they will only earn a curve on it. DON'T TAKE HIM!!!

Once a great prof, now lacks-a-daisical at best in his approach to teaching. Physics is an incredibly problem based course yet he never goes over problems in class and rambles over theory for the entire lecture time. Furthermore he provides little to no help during lab periods as he is rarely ever on campus. Also hides extra assignments in emails.

Dr. Yi is a very nice person and he is very passionate about the stuff he teaches. It may be hard to pass the class but Dr. Yi in his essence just makes up for it. 10/10 would take again he is an amazing guy

Quiz every week, very homework heavy, ridiculously hard tests. Sounds and feels like a nightmare professor at the beginning but he eases up after the first month or so. I think he does this for 2 reasons: 1) to weed out the pretenders 2) to make you study hard. Once you have a solid base of understanding, the later half of the class is manageable.
