Examiner Challenge Test — GCSE Physics Space Physics

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 life cycle of stars, natural vs artificial satellites, circular orbits, centripetal force, red-shift, Big Bang cosmology, and supernovae and nucleosynthesis. Full mark scheme included: the mistake, why it loses marks, the correct answer, and a Grade 9 model answer. Built from real examiner reports.
