Mr Cheng's easy-to-follow approach to Chemistry helped me alot. Confusing concepts became pretty simple after his tuition. I also changed my mindset towards Chemistry, from something I hated to one of the subjects I would willingly practice in my own free time. He has also boosted my confidence for this subject and I can say that without his tuition, my Chemistry will never be able to achieve the A, that I’m confident of getting in the A’levels.
