Mr Calvin Kong’s effective teaching methods had made our revision for the o levels more efficient and fruitful. Over time, I feel more confident in the subject.

— Samuel Chan, Maris Stella High School

Not only does Mr Kong explain the physics concepts thoroughly and effectively, he also makes an effort to link the concepts to real life applications, which is not commonly done by most teachers. His passion towards this subject has also inspired me to grow and develop an interest and appreciation for physics as not just a subject but a useful application in our everyday lives. Mr Kong is also very meticulous and organised as shown through the worksheets and notes that he gives to his students. For example, the focus points in every chapter, which I find it very useful and unique. Besides that, he is a very encouraging and thoughtful tutor, often sharing insightful advice to his students and always doing his best to help every student excel! Thank you Mr Kong.

When I first started on Mr Kong’s tuition classes, I was very weak in Physics. However, as I attended more classes, I found myself understanding the concepts better, and also I was able to answer questions with the appropriate keywords needed. The method of teaching is very useful for me and the many different worksheets and notes given by Mr Kong has helped me to strengthen my idea of the concepts.

— Hannah Joshua, Methodist Girls’ School

I started off as a student who found no interest in Physics lessons and never understood the concepts till I reached Secondary 4. I was finding it hard to do well or even stay awake in class. After attending Mr Calvin Kong’s class in the middle of Secondary 4, my results have greatly improved from an F9 in the Secondary 4 Mid Year Examinations to a B3 for my Secondary 4 Preliminary examinations. Mr Kong’s 2 paged summaries were extremely helpful as all the information was very well organised and succinct. He has definitely helped me gain confidence in the subject and learning from him has been beneficial and enjoyable. Thank you Mr Kong!

He is able to explain concepts easily in a simple way. I am able to remember and apply techniques during practice and examinations.

— Michelle Loh, Methodist Girls’ School

Not only did he dissect every chapters into clear distinct portions, he further breaks these portions down into bite-sized bits. In this way, he had made physics extremely easy to understand. Mr Kong does this using his 2 page summary sheets and worksheets which splits the chapter into a few key focuses. I am definitely glad that I had joined in. It is as he has promised – probably THE BEST physics tuition you can ask for.

— Natanya Ng, Methodist Girls’ School

Throughout Secondary 3, I struggled to grasp concepts and was consistently scoring Bs for Physics. Because of that, I dedicated very little time to study for my Physics papers. It wasn’t until the start of Secondary 4 that I found out about Mr Kong through my cousin and decided to give it one last try. Thanks to Mr Kong’s clear explanations, I could finally understand what was being taught in school. He is an approachable and patient teacher who takes time to answer questions over Whatsapp. I managed to clinch an A grade for both MYE and Prelims and topped the class for Sec 4 MYE.

— Tan Xuan Yan, Nan Chiau High School

As one who is truly dedicated to teaching and helping his students learn Physics better, Mr Kong is a kind-hearted teacher who selflessly devotes himself to teaching Physics to his students. He is a helpful and caring teacher who will help you whenever you are stuck with a particular question or unsure of certain concepts/answers/ideas. He will personally devote his time to stay back and slowly guide you through on how to go about doing the questions that you are unsure of, and for that I am very grateful to him. He is definitely a master in Physics as the answers and explanations that he gives in his worksheets/ test papers/ practice papers are of great quality and you may actually be surprised after reading/ listening to his explanations as it really gives you insights on how to better answer questions and apply key terms and concepts, this thus makes his teaching style and answering style unique and special. I am very grateful to him as he has taught me Physics in a new and unique way which has made me better understand the subject as a whole, I felt that I have greatly improved in the subject under him and for that I am sincerely and truly grateful to him. His lessons are very fun and interesting and I will definitely miss his lessons in class. I do hope I can keep in touch with him and get to hang out together with him and with the other classmates.

— Damien Chiew, Nan Hua High School

Thank you Mr Kong for making classes really enjoyable for by showing us real-life demonstrations to help us learn certain concepts more easily and being super patient with me by repeating to me again and again until I understand. Thank you for letting me change from a person who initially had 0 confidence and interest in Physics, to become someone who has started to enjoy, love and develop confidence in it. I will miss your really entertaining lessons and the small chats you have with our class during breaks and being super friendly with us treating us as friends! Although I only started in July and only attended your classes for about 5 months, I have improved and gained a better understanding of Physics. I really enjoy and will definitely miss your lessons! Thank you for being the best tuition teacher I have met so far.

Mr Kong’s Physics Tuition provided me with adequate practice from his hand-picked questions, comprehensive hand-written notes, and in-depth explanations in class. All these definitely boosted my understanding of Physics concepts and led me to top my class with an A1 grade in my Prelims, from and F9 in my common test 1. I am glad I joined Mr Kong’s class as I doubt, I would have made such a great improvement without his help.

— Celest Teo, Nan Hua High School

Mr Kong’s lessons are really fun and enjoyable. When I first went into his lesson I didn’t like physics however Mr Kong made me become more interested in the subject. His lessons made me have a clearer understanding on the concepts that my teachers teach in school. He uses various methods to ensure that we understand the concept better. For example when we were going through the chapter on light and lens Mr Kong showed us some experiments to enable us to have a better understanding on the concept. This method was really helpful for me as I am a more visual learner so looking at these experiments actualy helps me to clear my doubts and allow me to understand better Mr Kong is also very helpful. He always helps me and friends after class if we have questions to ask even though it is already very late at night. I am really grateful for Mr Kong as his lessons has made me more interested in the subject and has made me improve a lot. Thank you Mr Kong for helping me so much.

— Nellie Lin, Nan Hua High School

Mr Kong is a really really great Physics tutor! It is because of Mr Kong that I started to like the subject, because he makes lessons really interesting and engaging by using different methods, such as using different terms to explain a certain Physics concept. It is because of his lessons that when I learn about the same concept in school, I am better able to grasp and understand the lessons in school. Also, Mr Kong asks and he would not hesitate to sit down with us in order to make sure we understand the concepts. I would really like to thank Mr Kong for teaching and guiding us throughout every single lesson! I really wished I joined Mr Kong’s tuition earlier! Thank you Mr Kong!

— Ang Ying, Jamie, Nan Hua High School

Mr Kong’s lessons are really effective and enjoyable, I have learnt a lot during my time there. Mr Kong has his ways to relate physics to our daily lives, making physics concepts easier to understand. He uses various methods to deliver concepts in a clear and concise manner, which heightened my ability to comprehend and solve physics problems more accurately. His live demonstrations and computer stimulations helped his students understand difficult concepts more easily, his 2-page summary and consolidation notes are well-crafted which breaks down each chapter into 2-3 key focuses, this helped to make each chapter more digestible for his students so self-revision has definitely been made more efficient. He is always willing to stay back after lessons to clarify our doubts to ensure we fully understand. His patience and encouragement never failed to keep me going, his love for the subject is evident in his teaching and his passion for teaching gave me the drive to achieve even better results. He puts in a lot of effort in creating his lesson materials. I believe Mr Kong will continue to touch the hearts of his students and inspire more students in future. Thank you, Mr Kong!
