Professor Guan is the nicest professor in UCSB! His sense of humor just add something into the class~ highly recommended!!

Very Accomodating- He divided the class into groups based on our personal levels! Nice, humorous, easy going and helpful.

VERY KIND and UNDERSTANDING! I learned a LOT from his 3 classes, I personally recommend it!

I took the Chin3 summer class from him too. He's awesome though. Very easy-going and very helpful. he clearly presents his lectures and a well-organized person.
