Being Prof. Hai's student is the luckiest thing ever. I'm really grateful to him. He is not only my science hero but also my life role model.

An amazing introduction to diverse reactions presented in nature. May require good sense in advanced OChem to gain better participation.

He is better than Lehninger.

Prof. Hai is very caring professor, he is helpful in explaining concepts and values student participation in his lectures. His lectures are absolutely fascinating even if you are not a Chem/Biochem major, and he makes sure that everyone is on the same page. You have to put in an effort into this course, as it is difficult but absolutely worth it.

Actual meme lord who freestyles his lectures, really teaches the class like it's 3 unit course. Exams are very curveball but interesting. Low class average, thankfully the curve was generous.
