Avoiding him would make your life easy and happy :). The worst professor in the UCLA. The exams are soooooooooooo hard. The average for the final is 13/ 33? I remember correctly. To be honest, it should be 13/46, because there are extra 13 points as bonus points. However, it is completely impossible to get these bonus points and it turns out that no one get it because the highest score is 29. His homework is very very hard, and I spent more than 10 hours each week to finish it. The worst thing I felt is that lectures, homework and exams are three completely independent parts. They are not correlate with each other. If you can understand lecture, you can still have no idea about how to do the homework. If you finally understand the homework, you still have no idea about how to do the exam. It further turns out that he is not a good teacher, but just torments his students. He is not a good lecturer, because he speaks very weird English, and cannot explain concepts well. What really made me angry is that before the submitting the teaching evaluation, he tried to make his students happy, and even sent email saying that he will give everyone good grade and give easy final exam. However, after teaching evaluation, he began to not replying email, gave unreasonably difficult exam, and did not allow students to look at the exams if students need a regrade by giving excuse that he would travel out of LA. He is a liar and I am really mad at his morality. Such a bad person should not be stay at UCLA.
