Mr Koh is a really good teacher !! He has helped me for two years !! His explanations are really clear and in-depth. Moreover, his notes and materials are extremely useful!! He helps to bridge the gaps and links across topics which I think is really important when it comes to understanding and mastering chemistry! I would really recommend him as a tutor tbh as I really saw an improvement in my grades ( improvement of abt 5 grades )
