Reviews from Past Students

Ahmad Ibrahim_Derek Kiang

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

— Derek Kiang, Ahmad Ibrahim Secondary School

Ahmad Ibrahim_Kieran Lee

The tutors break down harder concepts into smaller parts that are easier to understand. This helped me to improve my Physics from a C6 during my SA1, to an A1 in my prelims.

— Kieran Lee, Ahmad Ibrahim Secondary School

Anderson_Adrina Ting

Through attending lessons at the centre, I was able to better understand the concepts previously taught in school and clarify my misconceptions easily. In addition, the lessons conducted by the tutors were effective as they were able to easily bring across the main ideas of each chapter by breaking it into various key ideas, such that it would be easier for us to understand. Moreover, the informative notes and the 2 page summary that were provided really enhanced my learning as I was able to test my understanding of the fundamental concepts through attempting MCQ questions and clear all my misconceptions. Furthermore, whenever I had any doubts or needed clarification, it was really helpful that I was able to ask the tutors my question on WhatsApp or in person, and this makes the process a lot easier and convenient. In addition, the centre also provides weekly tests to ensure that the students remember concepts which in my opinion, is very beneficial to us. The tutors are also able to explain difficult concepts easily by making use of simulations to allow us to see for ourselves the application of the concept, which I feel helps us to understand the concepts a lot easier.

Ang Mo Kio_Aidan Michael Poulose

I only joined the tuition centre in April of my Secondary 4 year. I got an E8 for my class test and so I decided to enroll in the centre. The classes were easy to understand and over time, I began to improve. My tutor always made the effort to push us to do better and work harder, and the 2 page notes and formula sheets were very effective for me when I was studying. After only being in the centre for a few months, I got a B3 for my prelims. I highly recommend Concept First Physics Tuition!

— Aidan Michael Poulose, Ang Mo Kio Secondary School

Anglican High_Chua Jia Minn

My tutor always has several ways to explain the same Physics concepts; such that when one doesn’t work, he can switch and explain in other ways until we understand. Ultimately, he is quick to understand our individual learning styles and can precisely explain his lessons in a way that we can understand best.

— Chua Jia Minn, Anglican High School

Dionne Teo

Mr Kong ensures that 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 Teo, Anglican High School

Anglican High_Liew Yee Kay

I always had much difficulty with Physics and found it a cumbersome and boring subject. But after attending Concept First Physics tuition class, I slowly understood it and finally got an A1 at the end! One thing I really appreciate about my tutor Calvin Kong is the fact that he cared for us all as individuals. When I was unsure about other subjects like A. Math, he would stay back after class with me to clear my doubts. And for that, I’m really thankful!

— Liew Yee Kay, Anglican High School

Anglican High_Megan Seah

Mr Kong is a very thoughtful teacher who always seeks to improve himself and his lessons. He plans his lessons to suit the needs of his students and always makes sure that 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 Concept First is really worth it and this is also evident in my grades (D7 to A2)!

— Megan Seah, Anglican High School

Anglo Chinese B_Bryan David

I really enjoyed Concept First’s classes. They really helped me to understand the various topics in the syllabus, even when I didn’t understand them in school. The classes were fun and not always serious, which I enjoyed.

— Bryan David, Anglo Chinese School (Barker Road)

Anglo Chinese B_Clarence Tan

I believe that Mr Kong is a truly a 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 Concept First, 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 increased 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. 

— Clarence Tan, Anglo Chinese School (Barker Road)

Anglo Chinese B_Hiero Ong

Calvin Kong has given me the encouragement and confidence required to do the paper. He is able to pinpoint the weak areas, and does his upmost best to help us improve and do well. Without his help, I can confidently say that my physics would not have been ready for O Levels. His enthusiasm and lame puns always puts a smile on the students faces, making class enjoyable and conducive.

— Hiero Ong, Anglo Chinese School (Barker Road)

Anglo Chinese B_Jerel Wong

When I started in Concept First, I had no high expectations as it was only a few months to my end-of-year exams. However, Mr Kong helped me clear so many doubts within the short period of time, leading to great improvements. Whenever I had questions, I would look to him and he would never fail to explain the concepts to me in different ways to ensure that I understood and was able to solve the questions. He makes classes fun and enjoyable through his jokes, keeping everyone engaged. I am super grateful for such an amazing teacher who not only helped me improve in my grades but also to enjoy the subject much more. Thank you Mr Kong.

— Douglas Tang, Anglo Chinese School (Independent)

Anglo Chinese I_Dylan Chan

I have really enjoyed Concept First’s lessons. The teaching style and notes have really helped me to improve my understanding of the subject. The weekly exercises helped me deepen my understanding of the subject and knowledge with the constant tests and practices. I have especially found the summary notes to be the most helpful outside of class, whenever I am in doubt while doing a worksheet or in school, and I do not understand my teacher, I would use the summary notes to clarify doubts. Mr Kong always spares time for his students and will ensure that each one of us is as prepared for any exams. Thank you for teaching me!

— Dylan Chan, Anglo Chinese School (Independent)

I was a student who scored C6 at the start of Secondary 3. However, I have managed to score A2 for prelims now. I feel that Concept First’s teaching has really helped me to understand how to apply the concepts I have learnt.

This tuition has really helped me improve my Physics score. Initially, I was failing in many of my Physics tests but the concise notes and many practice worksheets given by the centre has helped me greatly improve my grades. The tutor’s explanation is also very understandable. He is also willing to explain in detail after class. There are many useful resources such as formula sheets and individual chapter summary notes provided. This has indeed helped me in preparing for the O Levels. I highly recommend joining this tuition centre.

Mr Calvin Kong is the best Physics tutor you could possibly have. He has made learning Physics easy and enjoyable. In the 1.5 years that I have been at CF, my analytical and thinking skills have vastly improved. I would recommend this tuition to anyone who wants to get a distinction in Physics.

After attending Concept First Physics’ tuition class, I understood the concepts better. Their teaching methods are very effective. The teachers are also very friendly and so not only did my Physics grades improve, I had a lot of fun in class too!

I went to different tuition centres for other subjects. For most of the places, they just went through the basics that they have planned but do not actually cater to each individual’s needs. The classes here are different because of the small class size so all the students were catered to. I will miss the enthusiastic lessons. Thank you for making learning Physics fun and enjoyable.

Under their teaching, I understand the topics and the concepts better. Doing a wide range of questions on the key concepts has also made me become more confident for the exams.

In the past 3 months that I have attended Concept First’s fantastic Physics tuition classes, I have undoubtedly improved not only in my grades but also in my level of understanding of the subject. The fun-filled lessons have managed to ignite my passion for the subject which once confused and baffled me. With the help of the 2-Page Summaries and Revision Worksheets, I am able to go further with a confident A1.

Enrolling in class has been tremendously effective in improving my Physics grade. From being a borderline student, Physics has grown to be my favourite subject over 1 year of Concept First’s lessons. My tutor teaches in a way that makes it engaging and easier for students to learn. He is also very patient when it comes to answering questions even outside of lesson time and on Whatsapp. I really appreciate him for he is a truly dedicated teacher in helping his students achieve their very best.

Concept First’s lessons are always well-planned and engaging. Obtaining an F9 in Sec 3 made me feel that doing well in the subject was impossible and I even considered dropping the subject altogether. However, after just three months of joining the centre, my grades improved tremendously and I even got an A2 for Mid-Years! The constant dedication to improve their resources to help us visualise difficult concepts, the well-thought-out notes, and the concise teaching have helped me ignite passion for the subject and I am certain that the same can be said for all of the other students. Because of the lessons and never-ending guidance, I can confidently say that I have successfully grasped all of the Physics concepts within this syllabus and I am fully prepared for the O Levels.

The materials given by the centre are good. I am able to practise more during the practical lessons.
