Good class, good professor. His midterms are reasonable, and the final was fair. Although there's lots of homework, one can get through it in no time. And even with an accent, all of his lectures were understandable.

While Dai's exams were "fair" in that he was lazy and just put the homework questions on his test, his lectures were only somewhat helpful. He often joked around and sped through some material to ensure it was covered. This is not to say he was an ineffective teacher: he would often repeat some concepts to make sure they got through to the students. However, he didn't seem as professional as the other professors.

He is the best prof that I had so far. His midterms are super fair which all the questions are from the book. Even though he has chinese accent, but you will understand what he said in the lecture for sure. I personally will take him again if I have a chance. BTW, he is helpful in his office hour
