I never had a really keen interest in chemistry. But failing my first ever H2 chemistry test in JC caused me to actually want to go for tuition for the first time in my life, thus beginning my journey at Twig. After attending Twig, thanks to Mr Koh’s patient guidance, my H2 chemistry results improved tremendously, to the extent that I never got anything lower than a B for my school exams. Mr Koh’s concise and easy to understand notes also helped me develop a greater understanding for the various chemistry topics. Mr Koh conducts lessons in an interesting manner. He once demonstrated the electrolysis of sodium chloride for us in the classroom! His enthusiasm for chemistry also helped me develop a greater interest in chemistry. Mr Koh is always on hand to answer my queries and help me when I encounter any problems when doing the many practice questions he gives us. With Mr Koh’s guidance, I was one of the top students in my cohort for H2 chemistry during my prelim examinations, and eventually got an A in H2 chemistry for my A levels. Thank you Mr Koh!
