Read more detailed yet concise notes encapsulates all the essential concepts from each topic, and he provides a wide range of practice questions for application of these concepts to test our understanding of the content taught. He also makes himself available for consultations and provides additional support and materials closer to key examinations. Would highly recommend his lessons to both weaker students and stronger students looking to push their grades to the next bound 😄

I started tuition with Mr. Koh at Twig Learning Center around March of J1, after scoring a C for my first Chemistry exam despite having attained an A1 for Chemistry... Read more first Chemistry exam despite having attained an A1 for Chemistry at O lvls. The transition into JC was difficult esp with the steep learning curve, and I found myself struggling to keep up during lessons, but Mr. Koh really helped bridge the gap in my knowledge. He is one of the most dedicated and passionate tutors I’ve ever had, even more than some of the tutors in my school haha as he never fails to provide consultations willingly, always making sure that students with questions stay back after class so no one leaves with any doubts. What sets him apart from other tutors I’ve had is how he even conducts practical lessons to prepare us for the practical exams, something I rarely see in other tuitions. Also, I’ve sent him countless questions, and he’s always been patient and detailed in his explanations by going through the requirements of the questions and how to tackle it and similar questions in the future. His lessons are also super engaging!! He constantly asks questions to keep us thinking actively—and he even goes beyond the syllabus sometimes to help us connect concepts between chapters, making our understanding much more holistic. For certain topics, Mr. Koh provided optional quizzes that we could attempt at our own pace, complete with detailed video explanations that break down tricky questions clearly. There were also three summary booklets, which helped with revision a lot. It helped me to fully understand content before jumping into application, which prevented me from blindly practicing. I’m very very grateful to have such a dedicated tutor like Mr. Koh, who consistently goes the extra mile and how he would offer 1-to-1 consultations before and after lessons esp for those who need the extra help!!! I hope everyone can benefit from him like how I did!! Managed to attain A for A lvl H2 chem thank you Mr Koh :DD
