How ESAT Scoring Works
ESAT scores run on a 1.0 to 9.0 scale per module, reported to one decimal place. UAT-UK designs the scale so that a typical candidate scores around 4.5, with the median fixed at that point and the 90th percentile fixed at 7.0 every year. That is what makes scores comparable between sittings and between years: a 7.0 in one cycle means the same thing as a 7.0 in the next, regardless of how hard that year's questions happened to be. Low scores are capped at 1.0 and high scores at 9.0.
Each module — Maths 1, Maths 2, Physics, Chemistry, Biology — is scored separately, and you receive one score per module you sit. Universities look at the modules relevant to the course you applied for.
The conversion from raw marks to a scaled score is not a fixed formula. UAT-UK states that scores are statistically equated, so that candidates who sat different versions of the test can be reported on a common scale. Your raw mark is simply the number of correct answers — there is no negative marking — but the scaled score you receive depends on how that raw mark compares against the cohort and the difficulty of the version you sat. UAT-UK does not accept appeals against a test score.
Your score is reported per module, not as a single combined number. If you sit Maths 1, Maths 2, and Physics, you receive three separate scores. Universities can examine each independently. A student who scores 7.6 in Maths 1 and 5.8 in Physics is assessed differently from a student who scores 6.5 in both.
The Score Distribution: What the Official Data Shows
UAT-UK publishes the real distribution of scores for every module in its Explanation of Results. The table below is read from those published charts for the most recent completed cycle — the October 2025 and January 2026 sittings — and shows the percentage of candidates who scored at or above each level.
| Score | Mathematics 1 | Mathematics 2 | Physics | Chemistry | Biology |
| 7.0 or higher | 8.1% | 8.3% | 8.2% | 12.9% | 10.6% |
| 6.5 or higher | 13.0% | 11.8% | 12.6% | 16.3% | 17.9% |
| 6.0 or higher | 18.6% | 18.9% | 17.6% | 22.5% | 23.4% |
| 5.5 or higher | 27.4% | 26.3% | 28.0% | 33.5% | 32.4% |
| 5.0 or higher | 37.7% | 38.8% | 36.1% | 42.9% | 43.2% |
| 4.5 or higher | 54.8% | 48.7% | 49.1% | 55.2% | 54.2% |
| Below 3.0 | 6.5% | 12.8% | 18.8% | 12.0% | 20.4% |
Figures read from UAT-UK's published charts and accurate to within about half a percentage point. These describe the 2026-entry cohort and are not a prediction of any future cycle.
The distributions are not the same shape in every module. Mathematics 1, which every candidate sits, is the most tightly packed: only about 6.5% of candidates score below 3.0, against roughly 19.5% in Physics and 21% in Biology. Because the middle of the Mathematics 1 field is so dense, a few extra marks there move you further up the order than the same marks would in a science module.
One thing worth clearing up: in Chemistry and Biology, no candidate landed in the 8.5 band at all, which reads as though the top of the scale is unreachable. It is not. About 3.2% of Chemistry candidates and 2.7% of Biology candidates scored 9.0, because scores above the ceiling are capped there.
What Each University Does with Your Score
Cambridge uses the ESAT as part of the decision about who to invite for interview. Each College makes its own decisions independently, so there is no University-wide threshold, and Cambridge does not publish one. The College admissions tutor reviews ESAT performance alongside your predicted grades, your UCAS application and any written work submitted.
Cambridge's own guidance is explicit that there is no pass or fail for the ESAT, that your score is based on the number of correct answers, and that you do not lose marks for wrong answers — so it is worth attempting every question. Cambridge tells applicants directly that it does not expect them to get every question right.
After interviews, the ESAT score remains one factor among several in the final offer decision.
Oxford moved to UAT-UK tests for 2027 entry, replacing the PAT for Engineering Science, Physics and Physics and Philosophy, and using the ESAT for Biomedical Sciences and Biomedical Engineering. 2026 is the first cycle in which Oxford applicants sit the ESAT, so there is no Oxford-specific ESAT score history to draw on.
Oxford's published position is that tests form one part of its admissions process and are used alongside a range of other information to assess academic potential and suitability. Oxford does not publish score distributions, shortlisting thresholds or the weight it gives the test.
All Oxford undergraduate applicants must sit in the October 2026 window. Shortlisted candidates are interviewed in December 2026, and decisions are released on 12 January 2027.
Imperial is the most transparent of the four, and its guidance is worth reading in full. Imperial states plainly that there are no grade boundaries or pass marks for the ESAT, and that it considers your score alongside the rest of your UCAS application when deciding whether to invite you to interview or make you an offer.
Imperial's own words: “Achieving a high score does not necessarily mean that you will be offered a place, while a low score does not mean that your application will be unsuccessful.”
Imperial publishes an interactive dashboard of anonymised test scores and application outcomes by department for the 2025 entry cycle, showing the range of scores previous applicants achieved and what happened to their applications. Imperial attaches a clear warning to it: this is historic data, scores and outcomes vary year to year, and the figures “should not be taken as indicative of requirements or outcomes for the current or future admissions cycles.”
UCL requires the ESAT for H600 BEng and H601 MEng Electronic & Electrical Engineering for 2027 entry (or 2028 deferred entry). Applicants progressing from UCL's Engineering Foundation Programme or International Foundation Year are exempt.
UCL accepts either the October 2026 or the January 2027 sitting for these courses. UCL does not publish a threshold score or score distribution data.
Scores by Module: What the Distributions Mean for Your Course
The module combination is set by your course, not by you — check the full course-by-course requirements before booking, because modules cannot be changed afterwards. What the distributions add is a sense of how each module behaves: some spread candidates out far more than others.
| Course | Modules required | What the distribution shows |
| Engineering (Cambridge H100) | Maths 1, Maths 2, Physics | Physics has the widest low tail: 19.5% of candidates score below 3.0, against 6.5% in Maths 1. |
| Engineering Science (Oxford H100) | Maths 1, Maths 2, Physics | Same combination as Cambridge. Maths 1 is the tightest field, so marks there move you furthest. |
| Natural Sciences (Cambridge BCF0) | Maths 1 + any two of Biology, Chemistry, Physics, Maths 2 | Free choice. Biology has the widest spread of any module (21% below 3.0) and the fattest upper tail (23.2% at 6.0+). |
| Physics (Oxford F303) | Maths 1, Maths 2, Physics | Fixed combination. Physics and Maths 2 both spread candidates further than Maths 1. |
| Chemical Engineering (Imperial H801) | Maths 1, Maths 2, Chemistry | Chemistry has the fattest upper tail after Biology: 12.9% score 7.0 or higher. |
| Biomedical Sciences (Oxford BC98) | Maths 1 + any two of Biology, Chemistry, Physics, Maths 2 | Free choice, not a fixed Biology and Chemistry pairing. Pick the two you are strongest in. |
| Biological Sciences (Imperial C100) | Maths 1, Chemistry, Biology | Fixed combination. Both science modules have heavy low tails, so consistency across all three matters. |
| Mechanical Engineering (Imperial H301) | Maths 1, Maths 2, Physics | Same combination as the Oxbridge engineering courses. |
If You Have Already Received Your Score
Read your score as a position in the distribution, not as a mark out of nine. The percentages below are for Mathematics 1, which every candidate sits; the other modules vary by a few points either way, and the table above gives the exact figures.
7.0 or above
You are in roughly the top 8% of Mathematics 1 candidates, and the top 8–13% depending on the module. This is the band UAT-UK pins to the 90th percentile, so it means the same thing every year. Your test is behind you and it went well — the sensible next move is interview preparation, because for the interviewing universities the offer decision happens there.
6.0 to 7.0
Roughly the top 10–19% of candidates. A solid, above-average result. No university publishes a line you have or have not crossed, and all four describe the score as one input alongside your grades, personal statement and reference — so this is a good result that does not decide anything on its own.
5.0 to 6.0
Roughly the top 19–38%. Above the median but not at the top of the field. The rest of your application carries more of the weight from here, and it is worth putting your energy into the parts you can still change.
Below 5.0
Around or below the middle of the cohort — 4.5 is the median by design, so a score near it is genuinely typical rather than a failure. There is no pass mark, scores cannot be appealed, and you cannot re-sit within the same admissions cycle. What is still open to you is everything other than the test: your predicted grades, your personal statement, your reference, and your interview if you are invited to one.
You may only sit the ESAT once within an admissions cycle. The October and January sittings are two chances to book, not two attempts — if you sit in October you cannot re-sit in January. Oxford and Cambridge applicants must use the October sitting, with the only exceptions being Cambridge mature applicants at a college with a January deadline and Oxford Astrophoria Foundation Year applicants. Imperial and UCL applicants may use either sitting, and UAT-UK states there is no advantage to choosing one over the other.
Summary
ESAT scores are reported per module on a 1.0 to 9.0 scale to one decimal place. The median is fixed at 4.5 and the 90th percentile at 7.0, so roughly one candidate in ten scores above 7.0 in any given module. Each module is scored separately, and the distributions differ — Mathematics 1 is tightly packed around the middle, while Physics and Biology spread candidates much further out at the bottom.
No university publishes a cut-off, and you should be sceptical of anyone who quotes you one. Cambridge, Oxford, Imperial and UCL all describe the ESAT as one input among several, considered alongside your grades, personal statement and reference. Imperial, which publishes more data than any of them, warns directly against reading its historic figures as a requirement. The useful question is not “what score do I need” but “where does my score put me among the people who sat the same module” — and the table above answers that.
