Examiner Challenge Test — GCSE Physics Energy

Most students revise by reading notes. This is different. Twenty exam-style answers, each with exactly the kind of mistake chief examiners flag most often — your job is to spot it, explain why it drops marks, and rewrite it correctly. Covers the kinetic and GPE equations, mass unit conversion (g to kg), time conversion (minutes to seconds), power prefix conversions (kW to W), efficiency ratios, specific heat capacity, and tracking dissipation to the thermal store. Full mark scheme included: the mistake, why it loses marks, the correct answer, and a Grade 9 model answer. Built from real examiner reports.
