เครื่องคำนวณเกรด OCR GCSE Physics B (Twenty First Century Science)

In June 2026, a grade 4 needed 106 out of 180 on the Foundation tier. On the Higher tier, a grade 7 needed 119 out of 180 and a grade 4 needed 71. Boundaries are set again for every series, so these are last time's marks rather than the next exam's.

Not always. Schools often mark mocks against an older year's boundaries, sometimes more strictly to leave room to improve, and the real exam's boundaries are set only after it has been marked. A grade from a mock is a useful guide to where things stand, not a prediction of the result.

As a rough guide, yes: OCR publishes a boundary for each paper, which it calls notional, and the calculator uses those. The real grade comes from the marks for all the papers added together, so one strong or weak paper can be balanced by the others.

Boundaries are set after each exam is marked, so that a grade means the same standard even when one year's paper is harder than another's. A harder paper usually has lower boundaries, so the same mark can be worth a higher grade.
