ESAT score converter
Scaled score to percentile.
October 2024 + January 2025 reference cohort.
How this works
We use the combined October 2024 and January 2025 cohort in UAT-UK’s technical report, Table 5. Each module has four published percentile thresholds. Between them, the result is a labelled straight-line estimate; outside them, we show a band.
This compares scores with a historical cohort. It does not predict admission or convert an uncalibrated mock into an official result. Ties and rounded thresholds do not give an exact individual rank.
I have marks out of 27
There is no published universal conversion from a raw mark to an ESAT scaled score. It depends on the paper. Use an officially reported scaled score for the percentile lookup above.
Older ENGAA and NSAA scaled scores
Optional 2023 ENGAA or NSAA comparison
Enter a reported Cambridge scaled score from one Section 1 part. The result is a percentile estimate within that paper part, not an official conversion to an ESAT score.
2023 rows are estimated from official charts because the archived reports publish bar charts, not numeric score-to-percentile tables. 2016 to 2022 are unsupported because the Cambridge Assessment Admissions Testing (CAAT) website closed and no verified official table for those years could be checked.
Common score questions
Is 17/27 good?
UAT-UK publishes no fixed raw-mark-to-scaled-score formula or table. A mark of 17/27 can be a useful practice checkpoint, but it does not determine a scaled score without the paper-specific conversion. The same raw mark is not a universal score, and 17/27 is not a pass mark or an admissions cut-off.
What do 4.5 and 7.0 mean?
UAT-UK's October 2024 scaling anchors set the median candidate at 4.5 and the 90th-percentile ability at 7.0 on the common 1.0–9.0 scale. They are scale anchors, not identical observed percentiles for every module: in the converter's combined October 2024 and January 2025 distributions, Mathematics 1 is 4.2 at the median and 6.7 at the 90th percentile, while the other modules vary. They are not pass marks, cut-offs or offer odds.
Does the same raw mark always produce a 6, 7 or 8?
UAT-UK publishes no fixed raw-mark-to-scaled-score formula or table. The same raw mark can receive different scaled scores because post-equating accounts for the module and the paper form. One raw mark does not always produce a 6, 7 or 8. The lookup above compares an already reported scaled score with a historical cohort.
Does Cambridge have an ESAT cut-off?
Cambridge does not publish a universal pass/fail threshold or ESAT cut-off. The ESAT is read with the rest of the application, so a score is one part of the admissions evidence; it does not promise an interview or offer.

Does Imperial have an ESAT cut-off?
Imperial does not publish an ESAT grade boundary or pass mark. Historic department outcome figures, where published, are context for past cohorts rather than current requirements or admissions probabilities. A high score does not guarantee an offer, and a low score does not guarantee rejection.
