very un helpfull. His exam and quiz so hard. He even stay till 10:00 pm but you do not learn nothing. He is hard marker. He send his quiz through e-mail but one days early form due date. he is un organized. Final is a killer. I think few people finshed the course with out dropping. So horror class. Not happy every time. he is mudy.

His accent clouds all lectures so you walk away confused and annoyed. He will stop class to talk to people that walk in late, talk about his uninteresting life stories (repeatedly), and smile oddly at people in a creepy way. Studying the text like a bible will not let you get an A in 2nd sems.

He made mistakes about caculation formula. He seems not be familiar with the textbook. I also don\'t like his teaching pace.
