9–1: note: KCS’s printed total and percentages count its 99 AQA Level 2 Further Mathematics entries, a certificate that is not a GCSE or IGCSE. Where a school’s own total counts a qualification of that kind, the comparable figure follows the school’s total and says so. The GCSE and IGCSE rows alone give 70.5% at grade 9, 91.7% at 9–8 and 98.2% at 9–7, of 1,588 entries.
Which exams were sat: evidence: 9-1: 3 school or ISC records (e.g. fig:kcs_gcse_detailed_9_1:5); 15 DfE rows (e.g. research:kcs:2025:dfe-ks4-institution-results-25144)

Which exams were sat: note: KCS’s 2025 GCSE and IGCSE table lists every subject graded 9 to 2 only, the AQA Level 2 Certificate in Further Mathematics (99 entries) among them, with a printed total of 1,687 entries for 156 candidates. There is no letter-graded line. Its English Language row is marked “**” with no footnote and has 154 entries for 156 candidates; what the other two sat, and on which scale, is not shown, but however they were entered the figures stay within 91.4–91.5% at 9–8, 98.0–98.2% at 9–7 and 70.3–70.4% at grade 9, so the year stands on KCS’s own table.
