    Concept First provides concise summary notes with all the key points for the topics. The tutors provide more than enough questions for practise and are always willing to clarify our doubts when we ask questions. They make lessons fun and entertaining while ensuring that we learn something.

  • Alya Sufiyah

    Concept First’s two page summary helps greatly when revising for an upcoming exam and having all the main points for every topic makes revision easier and more efficient. Additionally, the tutors are very funny and make the lessons entertaining and hilarious. They also teach topics thoroughly and answer any questions we have. Moreover, they always have extra work and materials available when I finish the lesson’s work quickly.

  • Alyssa Siow

    Mr Kong had given me a clearer and deeper understanding of Physics concepts and how it can be applied not only in questions but also in real life scenarios. I was never fond of Physics, but Mr Kong has made learning Physics a lot more fun and engaging, rekindling my interest in science.

  • Amanda Han Xin Hui

    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.

  • Ashley Chan Si Ya

    Your classes are extremely engaging and entertaining. It definitely made Physics more enjoyable and easier to grasp. The lessons are well-paced with short YouTube breaks that helps keep up the fun atmosphere. You are approachable and friendly which makes it easier to clarify any doubts after lesson. Thank you

  • Asritha

    After reading his detailed notes that are so well organised, I am able to connect the dots between the various chapters. The worksheets he created are very aligned with the o-level syllabus and standards such that after doing them, we feel confident about the upcoming exams.

  • Darelyn Lim

    Physics has always been a confusing subject until I joined Mr Kong’s physics tuition class. His clarity in explanation had made the subject much easier to understand. Not only can we approach him during class time, online communication has also made it easier for me to ask questions.

  • Desmond Woo

    Firstly, before joining Concept First I was constantly just passing. Eventually, I had lost interest and motivation to learn physics. However, after joining Concept First, I could finally understand the concepts and my mistakes. The worksheets provided are tougher than school materials and notes are provided for us to use. After a few months. I had improved greatly and more importantly, I had gained back my confidence to improve.

  • Enzo Tan

    The tutors have been of great help in restoring my interests in physics and helping me jump 3 grades from my mid-year to prelims. The notes are very comprehensive and easy to understand. The teaching methods have also assisted me in remembering key points in topics and crucial concepts. The lessons are often interesting as they do their best to engage each student during each session. I am sure that your child will see significant improvements so long as they are willing to learn and consistently put in hard work.

  • Hans Zheng

    I like the summary for each topic and the method of explaining different topics through the tablet. The two sided summary for definitions are also very helpful.

  • Keith Peng

    Concept First has helped me to feel confident in sitting for my O’ Level Physics paper as I achieved higher understanding and better application skills in the subject due to the lessons.

  • Keith Tan

    Concept First tutors have clarified many of my doubts in Physics since I joined at the end of Secondary 3. They are always very detailed in the explanation of concepts, and in breaking down questions so that students can understand it easier and better. I feel that I am now more certain and confident in answering Physics questions, as I now have a better understanding of the various topics in the Physics syllabus, and have seen a big improvement in my grades from E8 to B3.

  • Lai Xu Qing

    Mr Kong is a very hardworking individual and always tries his best to refine his lesson materials. I believe that the result of his efforts can be seen from the quality of the notes and papers provided. I think that the summary sheets provided by Concept First are the best you can ever ask for. Mr Kong compiles the information and key points from every topic and teaches it in a way that is easy to digest and understand. I strongly believe that students who join will benefit from the lessons and results can be seen after a short period of time

  • Liew Jia Wen

    Having physics tuition with my class mates has made learning physics to be a much more enjoyable experience, especially with such a wonderful physics tutor who explains concepts in a very clear and detailed manner. His lessons has made me become more interested in Physics, both within and beyond the 0-level syllabus.

  • Lim Ming Hui

    His classes are always interactive and supplemented with detailed notes and worksheets. He is always willing to clear my doubts and answer my questions. I first joined his class in March of Secondary 4, when my grade for CA1 was an F9. Within 2 months, my grade improved to B3 for the Mid-year Examinations!

  • Moe Thaw Kong

    Mr Calvin is a very dedicated teacher who always took the extra time to answer my questions. May it be after class or over whatsapp, he was sure to help me clarify my questions and help me deepen my understanding in my concepts. In class, the tutors use a variety of methods to illustrate physics concepts. This made them really easy to understand. I sincerely enjoyed every physics lesson here.

  • Oliver Ong

    Lessons are enjoyable and effective. Mr Calvin Kong explains concepts really well and as simply as it can get. The atmosphere during class is very relaxed and I feel at ease when learning. The notes are extremely helpful as the contents are separated into different sections of the syllabus. Furthermore, Mr Kong is caring, humorous and makes lessons fun.

  • Aleena Sarah

    Mr Calvin Kong uses innovative and methodical approaches to help his students better digest chunks of concepts. He truly brings out the vibrancy of the subject by crafting intriguing lessons filled with demonstrations, simulations and such. At the same time, he is extremely dedicated and provides many crucial and useful resources that tremendously aid us in exams. Attending his lessons was really a wisening and impactful experience.

  • Charis Leong

    Through your notes I was able to go from understanding almost nothing about the topic to being able to grasp and recall concepts easily enough. I enjoyed your lessons as they were easily understandable and made me more confident in my abilities, as well as your entertainment keeping me awake. Thank you Mr Kong!

  • Kayle De Silva

    Even some of the more difficult topics had become easy to grasp after attending his classes, and I definitely felt more confident when sitting for my exams. His enthusiasm is extremely motivational and has inspired me to set higher targets for myself. Overall, this is one of the best physics tuition classes I have ever attended.

  • Koh Hui Qing

    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.

  • Nicole Boon

    I joined Concept First out of desperation because I caught no ball in school lessons. The tutors were able to explain the different topics and concepts clearly and precisely, and I benefited a lot from that. Mr Kong would ensure that students knew what the question requirements were and then teach them how to answer to different parts of the question while going through questions, he would also write tips and notes for students to copy for future reference, which is helpful when they want to revise that particular “trick” in the question. I recommend this class for students who are struggling to understand concepts or missing the question requirements.

  • Francis Chu

    After attending Mr Calvin Kong’s class since early this year, my results have had a tremendous improvement from C5 in Secondary 3 SA2 to a Distinction for my Secondary 4 Preliminary Examinations. I find Mr Kong’s teaching style and materials provided very efficient and effective for my learning as compared to my previous tutors. He is very approachable and is always willing to meet outside lesson time to answer my doubts. Thank you, Mr Kong!

  • Mrs Chu, parent of Francis Chu

    I find Mr Kong very approachable, whether in person or via Whatsapp. Initially, I was a little disappointed when my request to remove his company’s water mark was turned down as I reasoned to him how they makes reading difficult. I was surprised later to find that Mr Kong actually make an effort to blank out certain parts of his watermark so as to make sure that the content of his study material are not effected – this requires more effort and time. Thank you, Mr Kong. This tells me that you are a very conscientious teacher, and do not turn a deaf ear to parents’ feedback!

  • Gabriel Chai

    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.

  • Joshua Ong

    I enjoyed Concept First’s lessons every Sunday. The classes are never dull and boring, instead the tutors use humour to lighten the rigour of learning and understanding physics. Besides their superb teaching style, the notes, worksheet, and practical is of great tools to allow me to understand and practise physics with a breeze. Lastly, the summarised notes of 44 pages comes in handy whenever I do worksheets. It is easy and fast to refer to any page and most importantly to boost my memory. Mr Kong would provide more details on the questions we would ask him about, allowing us to better understand them. He makes the subject more bite-sized and manageable to tackle. I really feel content and happy with the help I received under Mr Kong’s teachings, so I recommend Concept First tuition centre to someone struggling with Physics.

  • Garrett Sim

    The worksheets and summary pages were very useful in helping me understand the concepts better. I was also able to have more practise and exposure to common questions and more challenging questions which helped me to prepare for a wide variety of questions.

  • Arvind Natarajan

    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.

  • Ayman

    Really great tutor. Managed to easily understand topics that I was previously struggling with. He had also helped me to feel more confident in the subject and inspired me to learn more.

  • Chris Lim

    I dare say that I have learnt more about Physics in the 4 months with him than I have learnt from my 2 years in school!

  • Nigel Sim

    I understand my Physics concepts better with the notes and lessons that were useful. Mr Kong explains his lessons in great detail and is able to make classes fun and engaging, which helped improve my Physics grades. He would clarify the doubts of all students easily and I enjoyed going for his classes each week.

  • Zann Lim

    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.

  • Alyssa Pua

    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.

  • Faith Kan

    This centre has helped me hate Physics a lot less. The teachers take time to stay back after class and give detailed explanations of any doubts I have. For example, my class ends at 8.30 pm and Mr Kong stayed back till 10.30 pm to answer all my questions. Despite my confusion and the many questions I had, Mr Kong was very patient and answered all my questions well. Classes are also very fun with his dad jokes and he is very friendly, which has made me like Physics more and more. Thank you for the past 2 years of tuition!

  • Megan Wang

    The team of tutors put a lot of thought and effort into planning and executing every lesson. They make sure that all of us understand the content that is being taught by checking for understanding and picking questions for us to do. Thanks to the lessons I was able to better understand the content taught in school.

  • Sandrine Sam

    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!

  • Valerie

    Came to Concept First tuition centre only a few months ago (in July I think) and at that time I was failing pretty badly. In a span of just 5 months, my grades improved from D7 to B3 which is something pretty remarkable. I would not have been able to do it without the help of the team of tutors. Thank you for helping me so much in Physics and for making this subject so much more enjoyable.

  • Crystal Buy

    I got an F9 for my CA1 in Secondary three before I joined Concept First tuition. In MYE, I failed to pass physics. Thereafter, in Secondary 4, when I dropped to combine science, I got A1 for physics in MYE and Prelims thanks to Mr Kong for setting up an individual combined science class for us. He even made separate notes for us, so that we would not be confused with the pure physics notes. My science grades have improved tremendously since joining Concept First tuition, and I am truly appreciative of that as he was able to use various methods to teach one concept and made us understand it clearly. He also injected humour into class to lift up our moods.

  • Nathaniel Tan

    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!

  • Premkumar

    The tutors are very approachable and friendly, able to share their experience of their own rather than following the answer sheet all the time.

  • Ang Zhi Bin

    The tutors provide many useful notes and resources for the students. They are willing to answer all questions from students.

  • Feng Muzhi

    I really find the notes provided by Concept First very meaningful and that they are very detailed in terms of clarity and information. Personally, I find Mr Kong very entertaining and jovial during lessons as he finds ways to make lessons more enjoyable and fun to understand, and it is really not boring to attend his lessons too. The two page notes and consolidation booklets, and lessons notes and flipping through my textbook. Through Mr Kong’s lessons, I improved my physics grades from F9 to B3. All in all, I am very grateful and thankful for everything that Mr Kong has done for me, and I really wish that I can do you proud with my O Level results! Thank you Mr Kong!

  • Joel Teh

    Mr Calvin Kong is able to use multiple ways to tackle difficult physics questions, in addition to simple and clear explanations towards each question. He is a caring and concerning tutor who will reach out to all students, identify their weak areas, and guide them along such that everyone is at the same pace in class. A dedicated tutor who would sacrifice his personal time and place students as priority. Highly recommended.

  • Thach Pona Bandith

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

  • Cho Junli Ryan

    The materials provided by Mr Kong is very effective and his lessons are very fun and interesting and he made Physics enjoyable for me.

  • Lynn Ong

    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!

  • Michelle Pang

    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.

  • Jerome

    The tutors’ notes are detailed and organised, providing for effective revision. Their lessons are also fun and interesting, often telling jokes but still staying true to teaching. The worksheets given are also effective in challenging the mind, allowing the students to learn something. 100% would recommend.

  • Mrs Irene Teo, parent of Terence Teo

    I learnt about Calvin Kong’s Physics Tuition classes through seeing his centre’s profile on Facebook. I spoke to him over the phone for a few times. My impression of him was a confident teacher. He is not the type to demoralise students despite my son’s poor grades and only joining him in June. I trust that he will deliver at the end of the day. Looking forward to receiving my son’s results.

  • Anna Bella Ang

    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.

  • Samuel Ong

  • Helen, parent of Samuel Ong

    I chanced upon Calvin’s website while looking for science tuition for my son when he was in Sec 2. As Calvin only offered Tuition classes for Upper Sec, I had arranged for him to do one-to-one tuition for a few selected topics which my son was weak in. At that time, my son commented that Calvin’s explanation was very clear and he could understand. My son only managed to join Calvin’s tuition class in March this year. I am glad to say that he had gained more confidence in Physics and I am sure that he will be able to perform well in the coming o levels. Thank you for your guidance and I will definitely recommend Calvin Kong Physics Tuition to any parents looking for an effective tuition class for their kids!

  • Melvin Lee

    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.

  • Wong Yan Tao

    The lessons have been extremely informative and enjoyable. The tutors would never give up on any student and would consistently motivate us to strive for the best. Furthermore, during lessons, there is an absence of a gap between the teacher and student because they always go out of the way to bridge that awkwardness/gap, to ensure that each one of us would learn in the most efficient way possible. Their expertise and passion could be seen when they sometimes go out of the way to explain to us various formulas, to allow us to better understand it. Thank you for making these lessons informative and enjoyable.
