Mr Koh is a great and astute JC Chemistry teacher. His greatness lies far within the vast amount of concise notes and practice questions that you will be bestowed to. His astuteness lies in his gift in sifting out possible questions that will stand against you during your examinations. Most importantly, he is a tenacious, old-school teacher which deeply believes in constant, harsh drilling which his classes have benefitted much from. I am grateful to meet you. Thanks Mr Koh!
