As soon as a session lands, the new questions are filed under the right syllabus topic on this page — so the day after a results day the topic already includes the freshest questions. No stale archive, no waiting.
When Edexcel updates the Combined Science syllabus mapping or retires a topic, the affected topic pages here are re-checked against the official 2026 syllabus and re-grouped — still free to browse. Stale topic mapping is one of the biggest hidden quality problems with free past-paper sites; this archive is re-checked on every release.
