Where a subject has more than one set of papers in a series (for example a version sat in a different region), each cell shows the lowest and highest boundary across them. Foundation tier boundaries and the remaining grades are in the source documents.

How to read these numbers

Across the 10 series in the table, the highest grade 9 threshold ranged from 189 to 262. Thresholds change from series to series because each set of papers is different: a harder paper has a lower threshold.

A threshold is the minimum total mark for the grade. Compare your total on a full set of papers with the thresholds for that series and paper variant.
