I was born and educated in Zimbabwe and later continued my studies in Cape Town, South Africa. I have worked and lived in several countries — including Zimbabwe, the UK, Switzerland, France, Germany, and China — as a Chartered Chemical Engineer.
Throughout my life, I have been motivated by a desire to understand the world through science. My engineering career allowed me to apply mathematical and scientific principles to real-world projects, giving me a deep appreciation for how these subjects shape the world around us.
Following the Covid pandemic, I decided to pursue my long-standing passion for education. I returned to the UK and completed my PFCE with QTS at St Mary’s University, Twickenham. I now teach part-time in schools and tutor students in Maths, Physics, Chemistry, and Biology.
My lessons follow the school curriculum and are carefully structured to improve exam performance while also building genuine understanding. I use real-life examples from my professional experience, along with safe practical activities where appropriate, to help students see not only how to answer exam questions, but why the subject truly matters.

Chemistry is taught through real-world context and hands-on learning, linking theory to practical activities and scientific analysis. Students are encouraged to build curiosity, confidence, and a genuine appreciation for how Chemistry explains the world around them.
Biology
Discover the fascinating biological principles underpinning life through clear explanations, practical examples, and strong links between topics to improve long-term understanding and exam performance.

Mathematical concepts are developed from a clear starting point in small, manageable steps. Students learn how to apply Maths to real-world situations and recognise patterns that deepen understanding and confidence.

Reviews and testimonials
Mate Janovszki
We were extremely satisfied with Kim and cannot recommend him highly enough. He supported our son with GCSE Combined Science, and the improvement we saw was massive. Kim’s explanations were clear, structured, and tailored to our son’s learning style, which really helped build both understanding and confidence. He was always well prepared and focused strongly on exam preparation, which made a real difference. Our son felt supported and motivated throughout the process, and his progress exceeded our expectations. An excellent tutor who delivers real results.

Kim is an amazing tutor, he listens to my questions and explains clearly, in a way that I can understand. He encourages me and helps me believe In myself. After just a few lessons I already feel more confident in my maths and Chemistry.

Kim has been an excellent tutor for our daughter, and we’re so pleased with the progress she has made. He explains topics clearly and patiently, breaking things down in a way that really makes sense. Lessons are well structured and focused on building confidence as well as understanding, which has made a huge difference to her attitude towards science. Kim is always well prepared and supportive, and our daughter feels much more confident going into exams. We wouldn’t hesitate to recommend him to anyone looking for a reliable, effective tutor who genuinely cares about his students’ progress.
