Results released

Results are released in the UAT-UK account and then passed automatically to participating universities on the UCAS application.

The Engineering and Science Admissions Test (ESAT) is a computer-based admissions test for selected STEM courses. It is delivered by UAT-UK through Pearson VUE test centres, and most candidates sit three 40-minute multiple-choice modules: Mathematics 1 plus two further modules chosen or prescribed by their course. Cambridge currently requires ESAT for Chemical Engineering and Biotechnology, Engineering, Natural Sciences, and Veterinary Medicine. Imperial uses it for a range of engineering, physics and life sciences courses. UCL currently uses it for Electronic and Electrical Engineering. Oxford has confirmed that, for 2027 entry, ESAT will be used for Biomedical Sciences, Engineering Science, Physics, and Physics & Philosophy, with full 2027-entry details released via UAT-UK from April 2026. Relevant admissions pages are listed in the recommended resources below.

01

Section 01

Test Format

Section 1: Mathematics 1

Duration: 40 minutes. Question types: 27 multiple-choice questions. Marks: raw marks come from the number of correct answers, and universities receive a scaled module score from 1.0 to 9.0.

Section 2: Additional modules

Duration: usually two further 40-minute modules, taken back-to-back with Mathematics 1. Question types: 27 multiple-choice questions per module. Marks: each module is scored separately on the 1.0 to 9.0 scale. Available modules are Biology, Chemistry, Physics, and Mathematics 2.

For most courses, the full test is 120 minutes. Cambridge Engineering candidates must take Mathematics 1, Physics, and Mathematics 2. Cambridge applicants for Chemical Engineering and Biotechnology, Natural Sciences, and Veterinary Medicine take Mathematics 1 plus two from Biology, Chemistry, Physics, and Mathematics 2. UCL Electronic and Electrical Engineering currently requires Mathematics 1 plus any two from Physics, Mathematics 2, Chemistry, and Biology.

Calculator and Equipment Rules

You cannot use a calculator or dictionary. ESAT is taken on a computer at a Pearson VUE test centre. You must bring valid photo ID, and personal items are not allowed in the testing room.

Negative Marking

There is no negative marking. Your score is based on the number of correct answers, so unanswered questions are usually a wasted opportunity.

Scoring, Bands & What Universities Look For

University of Cambridge

Cambridge uses ESAT as one part of its admissions process for the relevant courses. There is no pass or fail mark, and Cambridge does not publish official course-wide ESAT cut-offs. The practical takeaway is that applicants should treat ESAT as a differentiator rather than a hurdle with a fixed threshold.

Imperial College London

Imperial uses ESAT alongside the wider application. Its admissions guidance makes clear that a high score does not guarantee an offer and a lower score does not automatically mean rejection. In practice, departments may use the test to help distinguish between strong applicants, but there is no single universal score that applicants can safely target across every course. Applicants should also assume they should take the test only once in a cycle and plan accordingly.

UCL

UCL says it uses ESAT scores as additional information alongside the rest of the UCAS application, including predicted or achieved grades, the personal statement, and the UCAS reference. It does not publish fixed cut-off scores. Because this is still a relatively new admissions-test route at UCL, the safest strategy is to maximise performance across all three modules rather than aiming for an unofficial target score.

What each score band realistically buys you

Top decile7.0+ across required papersHighly competitive at Cambridge & Imperial

Top-decile profile across the required papers. Realistic target for Cambridge Engineering, Natural Sciences, Imperial Engineering.

CambridgeImperialUCL
Strong6.0–6.9 across required papersCompetitive at most Russell Group science courses

Solid above-average profile. Cambridge admissions teams interview most candidates in this band when GCSEs and predicted grades are strong.

Cambridge (interview likely)Imperial (interview likely)
Average5.0–5.9Threshold met but no headroom

On the median. Realistic at less competitive offers; for Cambridge Engineering or Imperial Computing the rest of the application has to be exceptional to compensate.

Below band<5.0Below working threshold for top courses

Most students in this band are not invited to Cambridge interview. Worth retaking only if there's a clear preparation gap rather than a content gap.

Section 04

Preparation Strategy

01

Lock pacing in early

Each paper is 40 minutes for 20 questions — exactly 2 minutes per question. Tracking sub-2-minute pace from week 1 separates 7s from 5s.

02

Triage, never sink

A hard chemistry question is worth the same mark as an easy mechanics one. Skip-and-return ruthlessly.

03

Anchor on past papers

PAT, NSAA, and ENGAA past papers map almost 1:1 onto the ESAT specification. Use them as the bulk of your timed practice.

04

Don't over-practise content

A-level depth is enough. Time spent re-deriving STEP-style results does not score on the ESAT — it just costs you the timing race.

05

Convert errors into drills

Every wrong answer must become a 10-minute targeted drill. Without that loop, mock scores plateau within three weeks.

06

Mock under exam conditions

A full sitting at the actual time of day, with the actual UI, no stops. Stamina is the variable students underweight most.

Time Management

You get about 1.5 minutes per question. That is enough for straightforward items, but not enough for perfectionism. Move quickly on routine questions, flag anything messy, and come back later. Since there is no negative marking, your default should usually be: eliminate, guess, move on.

Section-by-Section Approach

Do not let one ugly early question distort your pace. In Mathematics 1, prioritise clean algebra, graphs, manipulation, and fast recognition of standard structures. In science modules, avoid reading every stem like a school long-answer question: ESAT is about quick application, not writing out reasoning. In Physics and Mathematics 2 especially, check units, signs, and hidden assumptions before committing to a longer calculation.

When to Guess

Guess whenever you have ruled out even one or two options and the remaining work looks time-expensive. The biggest ESAT mistake is leaving questions blank because you wanted certainty. On this test, expected value beats pride.

6 Months Before

Choose likely modules, download the specification, and map it against your school syllabus. Build topic coverage first; speed comes later.

3 Months Before

Start timed module practice. Track mistakes by category: knowledge gap, setup error, algebra slip, misread question, or time panic. Your revision should target the pattern, not just the topic.

1 Month Before

Shift towards full 120-minute sittings under strict timing. Practise guessing discipline, pacing, and recovery after difficult patches. Use official material first, then extension material.

Final Week

Do light review, not heroic cramming. Revisit formulas, common traps, and your personal error log. Check logistics, ID, travel, and make sure your booked modules are correct.

Common Mistakes & Tutor Support

Algebra under time pressure

Weak

"I expanded every bracket carefully and ran out of time on Maths 2."

Strong

"I scanned for shortcuts (symmetry, substitution, ratio) before expanding."

Why it matters: Maths 2 questions have at least one elegant route. Bashing through algebra leaves you 4–5 questions short.

Physics formula recall

Weak

"I derived each formula from first principles in the exam."

Strong

"I memorised the 12 high-yield formulas and verified setup with units."

Why it matters: Derivations cost 90 seconds you don't have. Top scorers recognise the formula in <10 seconds.

Multi-step chemistry

Weak

"I solved each step and substituted at the end."

Strong

"I substituted symbolically as far as possible, then plugged numbers once."

Why it matters: Number-heavy work invites arithmetic errors; symbolic work catches setup errors before you waste time.

Common Mistakes

Students often choose the wrong ESAT modules when booking, revise content they already know instead of uncovered specification gaps, spend too long on one hard question, leave blanks despite no negative marking, treat the test like a school exam rather than a speeded admissions test, and wait too late to practise full timed runs.

How Our Tutors Help

Our tutors help students identify the right modules, close specification gaps fast, build pacing strategy, and practise with harder extension material once official papers run out. See /tutors/ and /contact/.

07

Section 07

Practice Resources & Question Bank

Check the Specification Against Your School Syllabus

This matters more than students think. ESAT draws on school-level maths and science, but UAT-UK explicitly advises candidates to read the test specification and identify topics that need revision. In practice, some applicants discover too late that a module includes content their school has not yet taught, or will teach only later in Year 13. Download the specification early, compare it with your school syllabus, and create a gap list. That gap list should drive your summer and autumn preparation.

YouTube Channels

TLMaths is excellent for A-level maths and fast topic refreshers. Physics Online is strong for A-level physics revision and exam-style explanations. Khan Academy is useful when you need a slower rebuild of a weak topic. The Organic Chemistry Tutor is especially good for targeted algebra, calculus, physics, and chemistry drills.

Official Past Papers

The best starting point is the official UAT-UK preparation hub, which includes the ESAT specification, ESAT guide, sample materials, and an archive of ENGAA and NSAA-style papers that contain related question types. Official material is limited, so students who rely on it alone usually run out of timed practice quickly. Useful URLs are the main prepare page, the ESAT preparation materials page, and the ESAT overview page, all listed in the recommended resources below.

Our Private Question Bank

For students working with our tutors, oxbridgementors.co.uk provides an additional private question bank beyond the official materials, which is especially useful once you have exhausted the specimen tests and archived papers. Get in touch via /contact/.

Prep Books

For students who want one structured paper resource, a CGP A-Level Maths Complete Revision & Practice book and a CGP A-Level Physics Complete Revision & Practice book are sensible choices. They are not ESAT-specific books, but they are useful for shoring up weak fundamentals quickly.

Registration & Logistics

Registration Window

For the completed 2026-entry cycle, registration opened on 31 July 2025 for ESAT. For the 2027-entry cycle, official Oxford and Cambridge pages state that full dates and registration details will be released in April 2026, so applicants should treat current future-cycle dates as TBC until UAT-UK publishes them.

Test Date

ESAT is offered in two sittings per year, typically one in October and one in January, at Pearson VUE test centres. For the most recent published cycle these were 9 and 10 October 2025, and 6 and 7 January 2026. Cambridge applicants must sit in the autumn sitting, and Oxford has stated that its ESAT applicants for 2027 entry will need the October sitting as well.

Results

Results are released approximately four weeks after the test through your UAT-UK account. They are then matched automatically to the relevant participating universities on your UCAS application.

Logistics

You book via a two-step process: create a UAT-UK account, then book through Pearson VUE. Tests are sat at Pearson VUE centres in the UK and in over 180 overseas countries. Access arrangements and bursary requests should be made before booking. On test day, arrive early, bring compliant photo ID, and expect strict security and check-in procedures.
