How to read these tables

Each figure is a minimum raw total, not a percentage — reach it and you get that grade. Boundaries are set after every series, so they move: a harder paper gets lower thresholds. Tiered subjects publish separate Core and Extended tables, and subjects with multiple paper variants publish one table per combination, so always use the option matching the papers you actually sat. The percentages here are the top and pass thresholds expressed as a share of the maximum mark, for the Extended tier where a subject is tiered.
