I enjoyed attending Mr Koh’s classes tremendously as he has a way of breaking down complex chemistry such that is easy to understand and manageable. His lesson materials are also succinct and precise, with ample examples and practice questions which are critical in grounding our understanding for every topic.

From a U grade in J1 to getting A for A levels, it was not easy but Mr Koh’s dedicated teaching and hard work altogether paid off. Thank you Mr Koh for your patience and guidance which really helped me make significant improvement in Chemistry 🙂
