I attended Twig LC in JC and it helped my chemistry grades enormously – from a U in J1 to an A at the A levels. Mr Koh is an incredibly dedicated and comprehensive teacher who not only teaches content but also common misconceptions so that students are not confused in his lessons. He has a great grasp on the syllabus and what the examiners are looking for in responses. In addition, he holds revision sessions before many exams, which were a great help, and he also answers any questions students have promptly. I am really grateful for Mr Koh’s help!
