Mr Koh is an extremely patient and dedicated teacher. Econs was one of my weakest subjects from the start and I was always frustrated and worried it would never improve. But Mr Koh never gave up on me- even when I didn’t do well for exams. He would always encourage me and continue helping me to improve instead of putting me down. In fact, I never thought I could ever get A for Econs, and I owe it all to Mr Koh for helping me achieve this milestone!
