ESAT Score Converter

From 2024, TMUA administration moved to UAT-UK and Pearson VUE. Candidates sit different test versions on different dates, and each person's score is calculated with a Rasch IRT statistical model rather than a single published raw-marks-to-score table. The 1.0–9.0 scale was also recalibrated — a typical score dropped from around 5.1 to around 3.8, and university grade boundaries moved down by a similar amount. The test did not suddenly get harder; the ruler changed.

UAT-UK does not publish raw-to-scaled conversion tables for the IRT era. For 2024 and later papers, enter the scaled score printed on your score report (1.0–9.0). We place that score on the current official distribution to estimate your percentile.

We look up your raw mark in the official conversion table for that exam year and section, stored in our database from Cambridge's published data. Each table maps raw scores to the 1.0–9.0 scaled score used on that paper. If a year's table is missing for a section, we use the nearest available year and flag it in the results.

For TMUA 2023 and earlier, we use the same official raw-to-scaled tables (sourced from Cambridge FOI disclosures and cross-checked against independent republications). Enter separate marks for Mathematical Thinking and Mathematical Reasoning together, or one combined overall score across both papers — but not a mix of those modes, because they use different scoring units.

For pre-2024 TMUA papers we show two figures: the score you would actually have received that year, and an estimate of the equivalent on today's scale. The estimate works by finding your percentile rank on the old TMUA distribution, then reading off the score with the same percentile on the post-2024 distribution. It is a percentile-matched proxy, not an official UAT-UK conversion. Comparisons are most reliable at 7.0+; the middle band (roughly 4.0–6.5 on the new scale) is less stable.

We use official cumulative score distributions — CSV tables of scaled score versus "% of candidates at or below this score". Your scaled score is interpolated between the nearest published points to estimate your cumulative percentile. "Top X%" is simply 100 minus that cumulative percentile (e.g. 85th percentile → top 15%). NSAA and ENGAA use subject-specific ESAT distributions; TMUA uses separate pre- and post-2024 cumulative tables.

Raw-to-scaled conversion tables come from Cambridge Assessment admissions data (and FOI disclosures for TMUA). Percentile distributions come from official ESAT and TMUA cumulative tables. We do not invent conversion numbers — everything is traced to published or disclosed source material, with gaps filled from the nearest reliable year when necessary.

No. This tool is a historical proxy for understanding how past papers relate to today's admissions landscape. It is useful for comparing mock performance and calibrating expectations, but it is not a score Cambridge, UAT-UK, or any university will use for an application.
