Mr Koh is an engaging and dedicated teacher. His notes are clear and concise, making them good reference materials for revision. We also have plenty of opportunities to practice the main concepts and common misconceptions in class so that we will be familiar with them by the time we sit for our exams. The recent trend for Chemistry appears to be setting compounds and reaction mechanisms that are different from the ones in the syllabus. Such questions may appear intimidating at first, but Mr Koh is always able to break it down to the basic concepts and establish a logical flow. This not only helps us understand the answer, but also teaches us how to approach similar questions in future.Apart from being very effective, Mr Koh is also very nurturing. During lessons, he ensures that everyone is keeping up with the pace of the lesson, and also constantly encourages us. This helped to build my confidence especially when dealing with difficult questions. With Mr Koh’s help, Chemistry went from being one of my most dreaded subjects to something I really enjoyed doing, and this was reflected the steady improvement in my Chemistry grades throughout J2. I finally got an A at A levels. This would not have been possible without Mr Koh, so thank you Mr Koh!
