I really enjoyed Mr Koh’s chemistry lessons. He was always very patient and happy to answer every single student’s questions, regardless in or outside of class. Mr Koh uses effective materials and concise explanations to achieve his lesson objectives quickly and learning Chemistry under his guidance was fun and easy. Thoroughly enjoyed my time at TWIG and I wish I found out about Mr Koh sooner! Thanks sir 🙂 Btw I managed to get into med school! 🙂
