prof. dai is really cool! he teaches well and he makes sure everyone understands the material. i love his little jokes! i go to class everytime waiting for him to tell us the joke of the day!

Makes class more bearable with his random (but very funny) jokes, not an overwhelming amount of homework, and I'm actually learning things in math for once. Too cool. Take him for Math 3A.

hes an awesome teacher, made me love math again, and he goes out of his way every class to tell a story, says we need a break

He's pretty good at explaining concepts and stuff. His tests are reasonable and he's solid all around. He has slight Chinese accent but its not too bad. I would recommend him.
