Mr Koh has always been patient in answering all my queries and doubts! He would stay back after class each night to make sure all of our doubts are addressed. In addition, he always took an extra effort to prepare extra materials for us! He breaks down concepts to bite-sized pieces and makes chemistry easily understood. Learning from you has been such an awesome experience! By the way, I got A for A Levels H2 Chemistry! Thank you so much Mr Koh!
