Thank you Mr Au Chee Ping for helping with my chemistry. Your lessons were a very much needed supplement to my school lessons. It has greatly helped me with improving my grades for chemistry. It is a shame that I only joined your class quite late. But even then in the short few months, you have helped me jump from struggling with chemistry to getting a B (might be better if i didn’t make some careless mistakes…) Once again thank you so much for teaching me chemistry.
