Mr Khoo is one of the most inspiring and dedicated teachers I have come across in my schooling life. I came to Mr Khoo about 4 months before my A levels, where I was struggling to pass my school's chemistry papers. I had a very poor understanding of the concepts and I was not sure how I could recover in time for my A levels. During my first lesson itself, Mr Khoo sat down with me and was able to identify most of my weaknesses and lapses in the subject, and within 2 months, my grades jumped from an E to an A for my prelims, and I was able to score an A for my A levels as well. He would also sit down with me after lessons on some days to talk about concepts not covered in the A level syllabus just so I could have an all-round understanding of the subjects. It is truly a joy to be taught by Mr Khoo.

Mr Khoo is an experienced chemistry teacher and he puts in a lot of effort to provide us with good quality educational resources and tips to do better in our examinations. I have seen great improvement in my understanding of JC level chem and it has piqued my interest in chem. He is also quick in responding to questions asked outside class time.

Mr Khoo's clear and concise teaching makes learning chemistry a lot easier. Not only that, but because my interest in chemistry increased, my results automatically increased helping me get 6 points in my y4 fye from only a mere pass in y3.

Mr khoo is one of the most knowledgeable and patient people I know, and therefore one of the best teachers I have ever met. His classes are extremely conducive and productive and well worth the time spent, where he takes the effort to make sure every single person in the class has understood the topic before moving on. He has helped me improve tremendously from a C5 to A1, and ultimately a distinction in my O levels.
