Since my first lesson, I have found Mr Koh’s lessons to be very helpful and informative. His notes are clear cut, without any unnecessary information, which really sped up my learning process. Coupled with you continuously going through with us questions to develop that much needed rigor for chemistry, I was able to improve tremendously. Mr Koh was also patient with my questions and would not hesitate to spend extra time out of lesson to answer my queries. I managed to get an A for Chem!
