Recent range across selected series: 257–291 marks (71.4–80.8%)
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 Further Maths B (MEI)?
In June 2025, A* took 291 of 360 raw marks (80.8%) on Route A: Option Y420+Y421+Y432. It moves every series — see the table for the recent range.
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.
