Lok chi Y

Chi-Sun is a very hard-working and competent professional. He has been my tutor for multiple years and has been the main foundation to helping me strengthen my math and problem-solving skills. He taught me Algebra 2, Pre-Calculus, SAT Math, AP Calculus, and Computer Science. Not only does he know various concepts very well, but he can simplify them to a beginning or amateur learner's level so that he or she can understand the material more clearly. He makes sure the student understands the material he is teaching and will patiently utilise multiple methods of explaining a concept that one may not understand on the first try. Chi-Sun is also extremely punctual, organized in his work and explanations, and is often open to helping students outside of a scheduled class time if he or she needs help. With Chi-Sun teaching me and helping me practice throughout many years, I went from a student who did not understand many concepts in Algebra 2 to getting a 5 in AP Calculus as well as comfortably passing a college level Computer Science course I would probably have failed in without his experience and efforts in explaining foreign concepts.
