The question you actually type in April: what do I need. Pick your board and subject for the marks each grade took on the most recent published boundaries, how much that figure has moved year to year, and a calculator for the marks you have left.
No page here predicts next summer's boundary, because nobody can. Boundaries are set after marking so a grade means the same thing in an easy year and a hard one — so every page shows the range instead, and suggests aiming above the highest it has been.
The exam boards' own grade-boundary documents, read 19 August 2026, source-linked on every page. If a figure here is wrong it is a mistake rather than a marketing choice, and it gets corrected with the date it changed.
Boundaries read 19 August 2026 from the exam boards' own documents. Boundaries are set per series and never apply to a future paper.
