good

great professor, very funny with his jokes. the class was not very hard

great teacher! he explains everything clearly. final was kinda tough, though. still, way better than gerstein. take math with dai if you get the chance. story time rules!

Joke Time Rocks

The prof is def. the best i've ever had. If he can explain calculus to me, he can basically teach it to a monkey. I actually enjoyed an hour and a half of math! Wait, did i just say that? Anyway, i am passing with a B, and i totally failed last quart

He's an awesome teacher! I love his little jokes, they are so cute, and it actually makes the hour and fifteen minutes of calculus enjoyable!

professor dai actually goes through and explains examples so that everybody can understand them. he makes calculus easy. his funny jokes make the lectures more interesting. take his class if you get the chance.

Pretty good at explaining stuff. Makes some funny and random jokes. Tests are reasonable as is the curve. I would definitely recommend him

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.
