Mr Kong is a patient and dedicated teacher whom students find approachable when in doubt. When needed to clarify certain concepts, Mr Kong would be patient in his approach and use different methods of explanation to allow you to understand. He would try his best to engage the lessons with demonstrations to allow his students to better understand. He would also occasionally crack jokes to spice up the lesson while learning takes place simultaneously. With these attributes, lessons would be more interesting while Mr Kong helps students to excel in Physics.

Mr Kong is a very thoughtful teacher who would always seek to improve himself and his lessons. He plans his lessons to suit the needs of his students and always makes sure tht his students understand the concepts before applying them (unlike many other teachers such as my school’s physics teacher). I would say that Mr Kong is one of my favourite teachers out there. Overall, coming to this tuition centre is really worth it and this is also evident in my grades (D7 to A2!).

Mr Kong ensures we are able to internalise the general concepts before teaching us how to apply them in basic questions and from there, we progress to the more challenging ones. I like that he is patient and he makes sure we go through this routine for every topic, which makes us well-versed in the subject.
— Dionne, Anglican High School
I always had much difficulty and found Physics a cumbersome and boring subject. But after attending his physics tuition class, I slowly understood it, and finally got an A1 at the end! One thing I really appreciate about Calvin is the fact that he cared for us all as individuals. When I was unsure about other subjects like A. Math, he will stay back after class with me to clear my doubts. And for that, I’m really thankful!
— Liew Yee Kay, Anglican High School

I realised that he always has several ways to explain the same physics concepts such that when one don’t work, he can switch and explain in other ways until we understood. Ultimately, he is quick to understand our individual learning style and he can precisely explain his lessons in the way that we can understand best.

I believe Mr Kong is a truly one-of-a-kind teacher. He is always very approachable, and always takes the time to help students fully understand the lesson. Before I came to his class, Physics was probably my worst subject and I was always struggling at school. However, over the course of a few months, under Mr Kong’s tutelage, I was able to strengthen my foundation and improve my confidence in the subject. In only a year, my grade for Physics by 4 grades, from a D7 in Secondary 3 to a B3 in the beginning of Secondary 4. I can’t thank Mr Kong enough for guiding me through, and I am always very happy to learn from him.

After suffering from several setbacks in Sec 3, I was demoralised by my Physics results as I either kept failing or getting borderline passes. However, after chancing upon his website on the internet when I was searching for references to do my school physics homework, I decided to take classes in Mr Kong’s Centre as it seemed good and beneficial for me. I was not wrong. Mr Kong’s 2-page summary and consolidation notes in a booklet was what I like most as it proved to be useful for revision when I was studying for the exams. In addition, his clear explanations and demonstration using things around us made me understand the topics better and cleared many of my misconceptions. Students can be assured of the quality teaching in Mr Kong’s class and benefit from it just as I had.

CGS - Kay a.jpg
Before I joined this tuition, I really hated Physics and was always confused during lessons in class. Physics concepts were hard for me to comprehend and there were insufficient practices provided by the school. Mr Kong’s lessons are always very engaging and easy for everyone to follow. Unlike school lessons which are fast-paced, I feel encouraged to clarify my doubts. Mr Kong uses different resources that allow us to visualise Physics concepts better which deepens my understanding of each chapter. For more challenging topics, Mr Kong uses different approaches like videos , real life demonstrations and computer simulations, to allow us to understand every topic instead of just plain memorising, and this really enhances my learning. Mr Kong also provides consolidated notes, timed practices, 1 to 1 consultations via Whatsapp, a notebook for us to consolidate important concepts, which has helped me a lot in my preparation for major school examinations.
— Kay, Crescent Girls' School
