How the figure is calculated

The number of entries at or above the band, across every exam system, divided by all the entries. We never average two percentages.

High grades: GCSE/IGCSE A*–G A*–A 1,051 + GCSE/IGCSE 9–1 9–7 448 = 1,499 of 1,555 entries
Top grades: GCSE/IGCSE A*–G A* 869 + GCSE/IGCSE 9–1 9–8 402 = 1,271 of 1,555 entries
C/4+: GCSE/IGCSE A*–G A*–C 1,088 + GCSE/IGCSE 9–1 9–4 448–467 = 1,536–1,555 of 1,555 entries
Grade 9: GCSE/IGCSE 9–1 9 58.9% of 467 entries, as printed
