OCR (MEI) A-level Maths B (MEI) grade boundaries
Every published series below, as raw marks or percentages — from OCR (MEI)'s official documents, sources included.
What do I need for a A*?
Pure Mathematics And Mechanics
Grade A* = 89/100 (89%)
June 2025
Recent range across selected series: 84–90 marks (84–90%)
Boundaries move every series — aim a comfortable margin above the recent range, not at the boundary itself.
What grade is my mark?
Boundaries are set fresh every series and move year to year — treat these as a guide to the difficulty band, not a promise.

Quick answers
What mark is an A* in OCR (MEI) A-level Maths B (MEI)?
See the table for the boundaries the board has published for each series.
Why do grade boundaries change every year?
Boundaries are set after marking so that a grade reflects the same standard even when the paper is harder or easier. A hard paper gets lower boundaries; an easy one, higher. That's why revising to 'the boundary' is a trap — aim above the recent range.
Where does this data come from?
Every row is taken from OCR (MEI)'s official grade-boundary publications — the exact source document and retrieval date are listed under the table. Series the board hasn't published simply aren't shown.

A few marks off the grade you need?
The distance between grades is usually 8–12 marks of technique, not talent. I teach exactly those marks — first lesson free.
