In JC, I found Chemistry a challenging subject but the lessons at Twig were very useful in helping me digest the more abstract concepts. Mr Koh organized the notes such that it was integrated with relevant examples and challenging questions. He also provided concise summaries for each topic to facilitate revision when nearing exams. I am very grateful that Mr Koh was ever so patient whenever I had questions to ask him. The lessons at Twig had certainly prepared me very well for the A levels. I scored an A for A levels!
