IGCSE Grade Boundaries June 2026 — Live on Results Day (Cambridge & Edexcel)
This is the live page for the June 2026 IGCSE grade boundaries. Cambridge publishes its official grade thresholds the moment results are released — Tuesday 18 August 2026, 06:00 UK time — and Pearson Edexcel follows with its International GCSE boundaries on Thursday 20 August. The tables below fill in that morning; until then, here's what we already know, subject by subject, and how to use the boundaries the moment they land.
- June 2026 boundaries do not exist yet — they're set after marking and published with results on 18 August (Cambridge) and 20 August (Edexcel). Anyone claiming them earlier is guessing.
- This page updates on results morning with the official thresholds for the most-taken subjects — bookmark it.
- The number that matters isn't the boundary — it's your distance from it: 1–2 marks below means a remark is worth considering; further means the November retake (entries close 12–21 September).

Edexcel International GCSE June 2026 boundaries
Status: awaiting publication on 20 August 2026. Edexcel grades 9–1; boundaries are published per subject as PDFs. We'll summarise the most-taken subjects here (Maths A, the sciences, English, Business) the same morning.
What to expect while you wait
Boundaries move every series, but they move within ranges. From recent published thresholds, the typical zones on Cambridge extended papers: A* around 80–90% for the sciences and maths, a little lower for essay subjects where full marks are rare. Two honest warnings from the explainer: a hard paper pulls boundaries down (June 2026's papers felt hard? that's not bad news), and chasing a predicted percentage is pointless — the only actionable number is how far your mark lands from the line, which your exams officer can tell you on results day.
The moment you have your results
- Find your subject's threshold aboveOr in the official tables — then ask your exams officer for your exact marks per subject.
- Compute your distanceMarks above the boundary = safe. 1–2 below the next grade = remark territory (deadline ~20 September). Further = decision time.
- If a grade needs fixing, move fastNovember retake entries close 12–21 September — and school/British Council cutoffs come earlier. The resit guide has the full playbook, and the results-day guide the whole decision tree.

Whichever way June's lines land, the November series and a marked-practice buffer mean you're never more than one well-prepared sitting away from the grade you need.
