Each lesson at Twig was worthwhile and enriching because of the way Mr Koh explains each chemistry concept. Mr Koh is a dedicated and patient Chemistry tutor who really goes the extra mile to explain the concepts to us in easily understandable ways such as through mini experiments and video sharing sessions! With well-planned and targetted lessons and notes, his effective teaching pedagogy has made H2 Chemistry a subject in which memorising is not necessary. Thank you Mr Koh for your guidance and would highly recommend Mr Koh as a Chemistry tutor! :))
