How do KCS Wimbledon and City of London compare on A-level grades at A*?
Comparison · A-level grades at A* · 2024–2025. Edition of 12 Nov 2026.
The answer
There are too few years with comparable figures to judge a pattern in the share of A-level entries awarded A*. You can still see each year’s figures below.
The figures
Not charted: fewer than 3 comparable years for any of these schools, too few to draw a line. The figures: KCS Wimbledon (2024: 50.7%; 2025: 50.75%); City of London (2024: 42%; 2025: 39%).
| Year | KCS Wimbledon (%) | City of London (%) | Gap (points) |
|---|---|---|---|
| 2024 | 50.7 | 42 | 8.7 |
| 2025 | 50.75 | 39 | 11.75 |
Figures to two decimal places at most. A figure known only within the school’s rounding is shown as a range, never as its lower end.
Read this with the answer
- These figures cover A levels alone. IB, Pre-U and combined-qualification results are kept separately. Teacher-assessed results from 2020–21 are left out unless you choose to include them. Where publications disagree and the difference remains unresolved, both figures stay in the source record and neither enters this comparison.
- 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: 2024 and 2025. 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.
- Historical results: the latest shared year is 2025. They can’t show 2026 results.
4 of the 4 recorded figures behind this comparison have an exact source check for that field and year; 0 are recorded or calculated figures with their support set out in Record details. This is not a fresh check of every source.
