GCSE grade boundaries by exam board

The raw marks needed for each grade in GCSEsubjects, straight from each exam board's official tables — shown across multiple years. We show more than one year on purpose: boundaries are set after marking and move each year with how hard the paper was, so a single year tells you nothing on its own. Pick your board — the same subject has different boundaries on different boards.

Every table links the exact official file it was extracted from. OCR and WJEC/Eduqas are being added as we verify each against source — we'd rather publish a smaller set that's right than a big set that isn't.
