Read this with the answer

  • Comparable figure: TSR’s calculation across every A-level, Pre-U principal-subject and IB Higher Level entry, weighted by entries. Cambridge aligns Pre-U D3 with A and UCAS scores IB 6 like an A.
  • Published results describe different groups of pupils, chosen in different ways. They can’t show the effect of attending a school, or what one pupil would achieve.
  • Only the years both schools can be compared on are used: 2023 and 2024. A missing or excluded year is not a zero result.
  • Fewer than five shared years, which is too few for the period check: it needs five.
  • These figures carry the record’s existing source checks, which are kept apart from background links. This edition didn’t reopen every original publication.
  • Counting A-level A*–A, Pre-U D1–D3 and IB Higher Level 7–6 together is our stated convention, weighted by entries. They are not the same examinations, and entries are not pupils.
  • Historical results: the latest shared year is 2024. They can’t show 2026 results.

0 of the 4 recorded figures behind this comparison have an exact source check for that field and year; 4 are recorded or calculated figures with their support set out in Record details. This is not a fresh check of every source.
