This is my first time to give comments on BruinWalk and hate a professor so much. I am not a Korean, and I wanted to add his class. His Korean student treated us like we were in kindergarten since he told us to line up one by one in a very impolite way. However, the professor was even worse. I asked if he had any seats left. He thought for awhile and showed me a class list. He told me that the class was full, but the time for the class list was not even the class I wanted. And then, he showed me that another random class was also full. I knew he did not want us to be in his class. When I looked around the classroom, which was full of Korean-speaking people, I realized that it was a place for Korean ONLY. The professor wanted his class to be Korean class. I was so disappointed with this professor, and I wonder why he can teach until now! The previous good comments were given by his Korean students, and if you want to experience unfair treatment, just go to his class!!!!!
