Michael is a good guy in teaching. He will give his help when you come across difficulties and he responds to emails very quickly. However, he sometimes make some definitions unclear, which he tries to make the explanations entertaining but only ends up being more confusing. the class is bruincasted but the quality of the video is not good at all. Michael will give you his very tough grading scale in his syllabus which might scare the heck out of you but he will eventually curve the grade such that 25% of the students will receive an A range. I earned a overall 91% which results in a final grade of A; if he stick firmly to his grading system, such score will only give me a B+.
