DrJon

I am a passionate Physics and Mathematics tutor with over 15 years of teaching experience and more than 15000 hours of online lessons delivered. I completed my Ph.D in Physics at Imperial College London after obtaining both a BSc and MPhil in Physics. Throughout my academic journey, I developed a deep interest in understanding not only advanced scientific concepts, but also the most effective ways to learn and teach them.

Over the years, I have worked with students from many leading UK schools, including Eton College, St Paul's School, Westminster School, The Henrietta Barnett School, Hampton School, Lady Eleanor Holles School, Manchester Grammar School, and Godolphin and Latymer School. I have also supported international students preparing for UK qualifications such as GCSE, IGCSE, and A-level examinations.

In addition to tutoring, I have experience teaching university-level Physics and Mathematics, including topics such as electromagnetism, quantum mechanics, classical mechanics, and advanced calculus. I also coached students for Pan-Asia Physics Olympiads, Asian Physics Olympiads, and International Physics Olympiad competitions, where students achieved multiple gold, silver, and bronze medals under my guidance.

I am also the author of A-level Mathematics mock papers and practice materials available on Amazon, designed to provide students with high-quality, challenging exam-style questions beyond standard past papers. My goal is not only to help students achieve excellent grades, but also to help them develop confidence, curiosity, and strong analytical thinking skills.

Teaching Experience

I have over 15 years of tutoring experience teaching GCSE, IGCSE, A-level, and university-level Physics and Mathematics. My teaching covers a wide range of exam boards including Edexcel, AQA, OCR A, OCR B, CIE, and Eduqas. I specialise in Physics, Mathematics, Further Mathematics, Oxbridge and Imperial entrance examinations, including STEP, MAT, PAT, ENGAA, and TMUA.

Since 2019, many of my students have successfully gained admission to Oxford, Cambridge, Imperial College London, and other Russell Group universities. I have also helped students achieve significant grade improvements, including students progressing from predicted E grades to solid B grades, as well as students securing A* grades and top GCSE results.

I previously coached students for Pan-Asia Physics Olympiads, Asian Physics Olympiads, and International Physics Olympiad competitions, where students achieved multiple gold, silver, and bronze medals. I have also worked with students from various countries including Hong Kong, China, Switzerland, the United States, Saudi Arabia, Kuwait, and Thailand, helping them adapt to the British examination system.

Alongside private tutoring, I have worked with organisations supporting financially disadvantaged students, allowing me to develop experience teaching students from a wide range of academic backgrounds and abilities.

Tutoring Approach

My tutoring approach is highly exam-oriented while still focusing on building strong conceptual understanding. I believe students perform best when they fully understand the logic behind concepts rather than relying purely on memorisation. I aim to simplify difficult topics into clear, structured explanations that students can apply confidently in examinations.

Lessons are carefully tailored to each student’s strengths, weaknesses, and target grades. For students who need support with fundamentals, I focus on strengthening core understanding step by step while improving confidence and exam technique. For stronger students aiming for top grades, I provide advanced problem-solving training designed to push their thinking beyond standard classroom level.

I also offer an A* Targeting Scheme for students who already find most past paper questions relatively straightforward. Under this programme, I create customised A* difficulty questions using my own unique question bank, specifically targeting weaker areas and advanced problem-solving skills. These questions are designed to reflect the style and creativity of the most challenging examination questions, helping students develop deeper analytical thinking and stronger adaptability under exam conditions.

In addition, I place strong emphasis on exam strategy, time management, and recognising common question patterns. My lessons often include carefully selected exam-style questions, structured feedback, and targeted practice to maximise improvement within a short period of time.

Outside lessons, students are welcome to contact me through WhatsApp for quick questions and support, allowing lesson time to focus more efficiently on deeper learning and exam practice. My overall aim is not only to improve grades, but also to help students become independent, confident, and intellectually curious learners.

I’ve been having lessons for almost three years, covering GCSE Maths and Physics and then A‑Level Maths and Further Maths. The support I’ve had has made a huge difference to my confidence and understanding. My tutor explains things clearly, is patient, and always makes sure I really understand the methods rather than just memorising them. Thanks to these lessons, I’ve achieved great results and feel properly prepared for the next stage. I’m really grateful for all the help over the years and would definitely recommend him to anyone looking for a strong tutor.

Dr Jon has been a fantastic tutor over the past few years, from when I started having lessons in Year 10 up till Year 13. He was extremely kind, patient and encouraging, and he was always happy to offer help even after lessons if I encountered concepts that I found to be confusing. Dr Jon taught me Physics at GCSE and A-level. Not only did he teach useful and creative ways for memorising and understanding various concepts, which made the lessons very engaging, he also utilised a lot of sophisticated and advanced exam-style questions, ensuring I was fully prepared for my exams. Overall, Dr Jon is a great tutor. I would highly recommend him. Thank you, Dr Jon!

Thank you Dr Jon! Best mentor and friend our son could possibly have wished for! For the past 3 years he tutored Alexis for Maths and Physics, methodically strengthening his weak points, challenging him to push the limits, encouraging him all the way and raising his confidence. The academic preparation is impeccable: plenty materials and resources well structured and tailored to specific needs, covering all the curriculum and exam techniques; personalised exam mock tests; constant guidance and feedback for both student and parents. Dr Jon helped our son achieve his goals, straight 9’s at GCSE and successful admission to Cambridge for Engineering. We are grateful for having the chance to work with Dr Jon and 100% recommend him!

Since the beginning, Dr Jon has always made his lessons extremely enjoyable and has made all the content we approach very understandable and had always taught each and every topic in great detail while still making sure didn't seem overcomplicated. He taught in a way where even the hardest of topics still made sense and didn't seem too difficult. His style of teaching is very exam oriented while still providing great foundational knowledge that not only helps you remember the content, but also gives you insight into why things are actually the way they are. Dr Jon started tutoring me for ESAT and TMUA, where he went over key physics and maths topics, before going into exam practice. The lesson structure really helped me understand the content in great detail, while also learning key exam techniques, which helped me out greatly when sitting the exams. After finishing the ESAT and TMUA, he also started tutoring me for the STEP exam. For these lessons, we went over past paper and exam-style questions for STEP, which gave me familiarity with the style of questions for STEP and helped me greatly improve my time to answer questions and also improved my overall critical thinking. As a summary, his lessons were always very helpful and again, extremely enjoyable. I always looked forward to his lessons and I always really enjoyed the sessions with him. He always somehow made the lessons interesting and fun while still being helpful. I have seen a great improvement in my skillset because of his tutoring. He is also extremely friendly and approachable, and will goes out of his way to help you. I am really grateful to have him tutor me and I will forever be thankful for his amazing and fun lessons.

I have been tutored by Jon all through my A- level, at the start of year 12 I was struggling heavily in physics and wasn't able to cope with the speed or the depth on which the subject was built. However, Jon was able to boost me up from the lowest grades to the highest within a year. His phenomenal style and method of teaching gave to the tools and ability to execute the hardest forms of questions within the A- level paper. I will certainly advise you to try his tutoring.

Tutor response

Thank you for your kind words. I've witnessed your remarkable improvement in the Oxford PAT preparation lessons. It's been fulfilling to see your progress, moving from a lower score to achieving the highest and securing admission to your top-choice univery. I wish you all the best in your future studies.

ShifaFirst Tutors

very good tutor my son said he explained very regarding any topic. as mum I found very expensive I wanted to book 10 lessons if there’s any discount but Dr John didn’t agree.

Tutor response

Dear Shifa, I am very sorry that I am not able to provide any discount. It is because I have to be fair to other students who have been paying the regular fee for months or even years. I wish you and your son all the best and a successful A-level exam for him. Thanks, Dr Jon

AlexFirst Tutors

I had enrolled onto first tutor and selected Jon, who tutored me in Physics and Further Maths. Jon provided me with weekly sessions on my subjects with material he prepared prior to each lesson with my input. Moreover Jon taught me quick and helpful methods which enabled me to deal with the questions effectively, which is important under exam conditions. Jon had an in depth knowledge of the subjects he tutored me, which allows him to adapt his teaching for you specifically; and I felt comfortable that Jon had covered all the content required for my exams. Not only was Jon an amazing tutor he is a very pleasant person which makes the sessions more relaxed. Furthermore, Jon would always select the most difficult questions which really pushed me to a higher level in preparation for my exams.

Tutor response

Thank you very much, Alex. It is my pleasure to tutor you and I enjoyed every lesson with you. Although most of the questions I gave you are tough and challenging, I am impressed to see how determined you are to tackle every challenge. I wish you all the best in your study at Imperial!
