Full-time private tutor and former Lead Physics Teacher. I diagnose misconceptions, rebuild understanding from first principles and teach the exam language that turns knowledge into higher grades. In-person in Welwyn Garden City or online.
Subjects I teach
- GCSE Physics: concept clarity, past-paper practice, model answers and confidence building
- GCSE Chemistry: core concepts, problem solving and exam technique
- A-Level Physics: deep conceptual work, advanced problem practice and examiner-style feedback
Who I help
I work with students who feel stuck or are underperforming in science, and with ambitious A-Level students pushing for top grades.
Location: Based in Welwyn Garden City. I also teach online nationwide.
About me
I’m Demetri Loizou, a full-time tutor with a Mechanical Engineering degree and experience as a Lead Physics Teacher. I left the classroom to focus on 1-to-1 tuition because I saw how much faster students progress with tailored, diagnostic teaching.
My lessons are calm, structured and practical. I start by identifying the exact misconceptions holding a student back, rebuild the foundations, then teach the precise exam language and technique examiners reward.
Why choose me
- Former Lead Physics Teacher with classroom and 1-to-1 experience
- Specialist in rebuilding understanding from first principles
- Calm, structured lessons with clear exam technique throughout
How lessons work
- Free diagnostic consultation: a short, no-obligation call to review recent work and agree next steps
- Diagnostic assessment: quick tasks to pinpoint gaps
- Focused lessons: explanation, worked examples and exam-style practice
- Exam technique: model answers, timing strategies and common examiner traps
Students typically see clearer understanding and more confident exam performance within a few lessons.
