The lesson notes prepared by Mr Calvin Kong are very concise, yet comprehensive, helping me to relearn my weaker topics quickly. He is able to explain the difficult concepts very clearly and with great details. He is also able to explain all the common mistakes made by students. In this way, we are more well-prepared and alert during the exams. I highly recommend his classes.
— Gabriel Chai, Saint Andrew’s Secondary School

Before I attended his lessons Physics was subject that I disliked. However, after attending his lessons I have realised that Physics can be fun and interesting. The usual card tricks and stories that he shares with us allows us to enjoy his lessons. He is able to simplify difficult concepts and explain them with demonstrations making it much easier to understand them.

Best Physics Tuition
Mr Calvin Kong teaches Physics with unparalleled clarity, and is the main reason for my huge improvement from where I started from – a state of not knowing anything about the subject. He keeps lesson interesting by conducting real-life demonstration and he provides many detailed worksheets and notes that students can refer to. I also greatly appreciate that he cares for our welfare. I will always remember that he treated me lunch when I ran out of money, and the fact that he does not charge fees during absence shows that he cares more for our benefits than his profit.

Mr Kong is an approachable and helpful teacher that guides us in every way possible. I can always count on him to explain the abstract concepts clearly and with the addition of different learning materials- difficult exam questions, consolidated notes and visual animations, students can expect to receive a straightforward and methodological approach in succeeding in their exams. Personally, I had consistently achieved C grades in my physics exam, however ever since joining, I have been attaining A or A* grades for my mock or semester exams.

After attending lessons with Mr Kong, I have become much more confident with myself in Physics and am not afraid to attempt various questions across different topics which I was afraid to even tackle before coming to Calvin Kong Physics! I was exposed to a wide variety of questions and answering techniques, especially certain keywords that the markers will look out for during examinations. This has boosted my confidence in Physics Paper 2 and I was pleased that the O Level paper was manageable in my case! The revision worksheets , summary sheets and extra practices were extremely useful in my revision for the O Levels. Thank you Mr Calvin Kong!
— Sandrine Sam, St. Margaret’s Secondary School

No matter how hard I tried to understand concepts from O Level assessment books, I ended up failing and even got recommended to drop to combined sciences. Later on, I joined Calvin’s physics tuition class and neither could I believe but my whole thought process changed and I managed to get an A2 for O Level Pure Physics, something I would not even have hoped for in the past!

Despite the short period I have been with the centre, I was able to clarify many key concepts and answering strategies in the lessons through critical learning. If I had known about this centre much earlier, I am sure my results would be much more spectacular. I am now able to see Physics as a fun and relatable subject and can find myself thinking of what kinds of Physics has been applied in my daily life and would recommend this class to anymore who struggles to understand the concepts taught in school.
— Amanda Han Xin Hui, School of Science and Technology, Singapore

Physics Tuition a Level
I ended Secondary 3 with generally poor results in Physics and I spent several days deliberating whether I should drop the subject. But luckily, after I saw Mr Kong’s advertisements, I decided to give Physics one more shot. I joined Mr Kong’s classes at the end of 2016, and the first lesson on EM Waves already allowed me to gain more faith in my ability in Physics. Through the course of 2017, my grades in Physics improved tremendously, and I began to like the subject more than I ever had.
— Koh Hui Qing, Singapore Chinese Girls' School

The classes are very engaging and very helpful for my understanding of the subject. I have struggled with Physics until finding Mr Kong.

Mr Calvin Kong is the best teacher I ever had. He is dedicated and constantly striving to help his students achieve their very best, crafting excellent learning resources such as the 2-page summary sheet and many useful practice questions. I would highly recommend his class to anyone who is struggling with Physics but still desire an A1!
— Lynn Ong, TKGS

It is undeniable that he will give his best to his students all the time. From staying back after class, to upgrading of facilities, to improving his teaching methods, he had done it all. He is an approachable and candid teacher who will extend an arm to whoever needs it. From a student’s point of view, materials of his are much more useful than those provided by schools, and given the variety of organised and well-planned resources, they are designed to suit everyone.

I tried out Mr Kong’s lessons and found them extremely interesting. Physics was not my favourite subject until I attended his lessons. I started to gain an interest in it. I also found hope and I persevered thanks for Mr Kong’s encouragements along the way. He is really a caring teacher and I can guarantee that after coming for his classes, every student will definitely feel more willing to explore further and ace the subject. Thank you Mr Kong for what you have taught us. I truly appreciate it.

Before joining Mr Calvin Kong’s class, all I did to prepare for my Physics examinations was just memorising of formulae without much understanding of the concepts at all. Thanks to Mr Kong’s patience and clear explanation of the topics, I have undoubtedly improved in my grades through getting the concepts right.
— Anna Bella Ang, Xinmin Secondary School

I only joined this tuition centre for a few months before my ‘o’ levels as I was not achieving the grades I wanted to and started panicking. Despite such a short time span, the teachers were still willing to take me in and support me on this journey. I was given a lot of practice papers which increased my exposure to different questions. The teachers will also refresh the previously taught topics with us and provide intensive revision at the topics. The summary notes provided for us is extremely useful and easy to understand. I was able to revise the day before the ‘o’ levels examination and walked into the exam hall with confidence. The teacher will also make an effort to regularly bring the topics taught in class to real life through examples, allowing us to better understand the concepts. The lessons were very engaging and I was able to benefit from it greatly.
