Mr. Koh has been a terrific chemistry tutor and role model for me. He is one of those rare teachers who can compound flippancy and conscientiousness, both an easy-going mate and a serious worker. In this he sets an endearing example of exemplary conduct and work ethic without the stifling nitpicking that sets student’s teeth on edge. His patience and concern with understanding of the subject establishes him as a top tier teacher who truly deserves the respect and affection my class and I give him.
