Question 1

What is the ESAT (Engineering and Science Admissions Test) and who administers it?

Accepted Answer

The ESAT is a 120-minute computer-based admissions assessment administered by University Admissions Tests UK (UAT-UK) via official computer-based testing centres for undergraduate STEM applicants to the University of Cambridge, Imperial College London, and University College London (UCL). The Engineering and Science Admissions Test (ESAT) replaced previous university-specific assessments (including the NSAA and ENGAA). It assesses candidates' understanding and application of mathematics, physics, chemistry, and biology at early A-Level (or equivalent) standard. It is delivered globally at authorized computer-based test centres under secure, standardized invigilation conditions.

Question 2

How many questions and modules are on the ESAT, and how long is the test?

Accepted Answer

The ESAT consists of three 40-minute modules, totaling 120 minutes of testing time. Each module contains 27 multiple-choice questions, making a total of 81 questions across the entire sitting. Every candidate must complete 3 modules. Each 40-minute module is self-contained with its own independent 40:00 countdown timer. There is no scheduled break between modules; the next module begins immediately upon conclusion or submission of the preceding module. Unused time from one module does not roll over to the next.

Question 3

What is the exact structure of each individual ESAT module?

Accepted Answer

Each module contains 27 multiple-choice questions with 4 to 8 answer choices (typically Options A through E or A through H). There is no negative marking, and all questions carry equal weight (1 raw mark each). Questions test conceptual speed, non-calculator numerical fluency, and analytical reasoning across three formats: standard single-stem questions, multi-statement combinations (e.g. "Which statements 1, 2, and 3 are correct?"), and table-row matching matrices. The total raw mark available per module is 27 (maximum 81 marks across 3 modules).

Question 4

Is there an onscreen calculator or can I bring my own calculator to the ESAT?

Accepted Answer

No. Calculators are strictly prohibited across all modules of the ESAT. There is no onscreen calculator, and physical calculators are not permitted inside the examination room. Every calculation is engineered to be solved without a calculator. Numerical values simplify using rational ratios, cancellation, common fractions, and scientific notation approximations (e.g. taking $g = 10	ext{ N kg}^{-1}$ or molar gas volume as $24.0	ext{ dm}^3	ext{ mol}^{-1}$). Sub90's Speed Dojo specifically trains non-calculator mental arithmetic and proportional scaling reflexes.

Question 5

Where is the ESAT taken, and is it administered on paper or computer?

Accepted Answer

The ESAT is taken entirely on computer terminals at official test centres worldwide. It is not available as a paper exam. Candidates test under standardized invigilation conditions at official computer-based test centres. Each workstation is equipped with a PC running the official test delivery engine, a mouse, keyboard, and physical double-sided laminated scratchpad booklet with dry-erase marker. Testing takes place in controlled quiet rooms under continuous camera and proctor supervision.

Question 6

Which ESAT modules are required for Cambridge Engineering?

Accepted Answer

Cambridge Engineering applicants must take Mathematics 1 (compulsory), Physics, and Mathematics 2. The Cambridge Engineering admissions faculty requires candidates to demonstrate advanced mathematical competency and applied Newtonian physics. Candidates take: (1) Mathematics 1, (2) Physics, and (3) Mathematics 2. The Chemistry and Biology modules are not permitted substitutes for Engineering applicants at Cambridge.

Question 7

Which ESAT modules are required for Cambridge Natural Sciences?

Accepted Answer

Cambridge Natural Sciences candidates take Mathematics 1 (compulsory) plus two science modules: Physical track applicants typically choose Physics and Chemistry (or Mathematics 2), while Biological track applicants choose two from Biology, Chemistry, and Physics. All Natural Sciences candidates sit Mathematics 1. Physical Natural Sciences applicants typically select Physics + Chemistry or Physics + Mathematics 2. Biological Natural Sciences applicants typically choose Biology + Chemistry. Always check your specific Cambridge college's admissions criteria as some colleges express module preferences.

Question 8

What modules does Imperial College London require for Engineering and Physics?

Accepted Answer

For Imperial Aeronautical, Mechanical, and Civil Engineering, required modules are Mathematics 1, Physics, and Mathematics 2. For Imperial Physics, Mathematics 1, Physics, and Mathematics 2 are required. For Chemical Engineering, Chemistry is required alongside Mathematics 1 and either Physics or Mathematics 2. Imperial College London uses the ESAT across its Faculty of Engineering and Department of Physics. Electrical and Electronic Engineering (EEE) and Electronic and Information Engineering (EIE) require Mathematics 1, Mathematics 2, and Physics. Design Engineering also requires Mathematics 1 and Physics. Always verify on the Imperial course pages before registering for the exam.

Question 9

Does UCL require the ESAT, and for which degree programmes?

Accepted Answer

Yes. UCL requires the ESAT for specific undergraduate engineering and science programmes, including selected Electronic & Electrical Engineering, Chemical Engineering, and Natural Sciences pathways. UCL joined the UAT-UK consortium starting from the 2024/2025 admissions cycle. Candidates applying to UCL degrees requiring ESAT must sit Mathematics 1 plus the two science or mathematics modules specified in the course entry guidelines on the UCL prospectus.

Question 10

Is Mathematics 1 mandatory for all ESAT candidates?

Accepted Answer

Yes. Mathematics 1 is compulsory for every candidate sitting the ESAT, regardless of university, course, or pathway. Mathematics 1 tests foundational GCSE and Core AS-Level mathematics (algebra, quadratics, trigonometry, indices, surds, coordinate geometry, and basic calculus). It serves as the baseline common denominator for all STEM admissions and is always delivered as the first module of the examination.

Question 11

Can I take Mathematics 2 without taking Mathematics 1?

Accepted Answer

No. Mathematics 1 is automatically the first module of the test for all candidates; Mathematics 2 can only be selected as one of your two elective modules. The test player automatically loads Mathematics 1 as Module 1. Mathematics 2 covers more advanced pure mathematics, including logarithmic differentiation, polynomial remainder theorems, vectors in 3D, and trigonometric identities, and must be selected alongside a science module or another eligible elective.

Question 12

How does the official UAT-UK 1.0 to 9.0 scaled score work?

Accepted Answer

The ESAT reports scores on a 1.0 to 9.0 scale to one decimal place for each module. The scale is calibrated with a target median of approximately 5.0 and a standard deviation of ~1.5, normalized across candidate cohorts. Rather than reporting raw marks (0–27), UAT-UK applies statistical item response and equating models to convert raw scores into scaled scores from 1.0 (lowest) to 9.0 (highest). A score of 5.0 represents average performance among applicants; 7.0+ represents the top decile (~90th percentile); and 8.0+ represents exceptional mastery (~97th+ percentile).

Question 13

Is there negative marking for incorrect guesses on the ESAT?

Accepted Answer

No. There is zero negative marking. An incorrect answer or an omitted question receives 0 marks. Because there is no penalty for incorrect answers, you should never leave any question blank. In the final 60 seconds of each 40-minute module, always lock in a best guess for any remaining unanswered questions after ruling out obvious distractor options.

Question 14

What is considered a competitive ESAT score for Cambridge and Imperial?

Accepted Answer

For Cambridge, scores of 6.5–7.0+ across all three modules are generally competitive for interview invitations, while offer holders typically average 7.0–8.0+. For Imperial Engineering and Physics, composite scores above 6.8–7.2 are typical cut-offs for competitive shortlisting. Admissions tutors evaluate ESAT scores contextually alongside GCSEs, predicted A-Levels, and personal statements. In highly competitive courses like Cambridge Engineering or Imperial Computing/EIE, scores above 7.5 in Mathematics 1 and Mathematics 2 significantly strengthen your application.

Question 15

How are raw marks (out of 27 per module) converted into scaled scores?

Accepted Answer

Typically, achieving ~14/27 raw marks yields approximately 5.0, ~18–19/27 yields ~6.5, ~21–22/27 yields ~7.5, and 24+/27 enters the 8.0–9.0 band. The exact raw-to-scaled conversion curve varies slightly each year based on test cohort equating. You can simulate the full scaling curve and university competitiveness thresholds on our interactive [Score Calculator](/score-calculator).

Question 16

How does UAT-UK ensure fairness and normalize scores between test sittings?

Accepted Answer

UAT-UK uses statistical equating to adjust for minor differences in question difficulty between different test sittings, ensuring that a 7.0 in October represents the exact same ability level as a 7.0 in January. Test forms are pre-equated using psychometric anchor items and calibrated difficulty parameters. Neither Cambridge nor Imperial expresses a preference for one sitting over another on scoring grounds.

Question 17

What are the two ESAT test sitting windows (Sitting 1 vs Sitting 2)?

Accepted Answer

Sitting 1 occurs in mid-October (typically around October 15–16), and Sitting 2 occurs in early January (typically around January 8–9). Sitting 1 is synchronized with the UCAS early deadline for Cambridge applicants and Oxford applicants. Sitting 2 is primarily for candidates applying to Imperial or UCL who are not applying to Cambridge.

Question 18

Can I take the ESAT in both October and January in the same admissions cycle?

Accepted Answer

No. Candidates are strictly prohibited from sitting the ESAT more than once per admissions cycle. You must choose either Sitting 1 or Sitting 2. UAT-UK policy strictly enforces a single sitting per academic year. If a candidate attempts to register and sit both sessions, their second test score will be automatically invalidated, and universities will be notified.

Question 19

Which test sitting must Cambridge applicants register for?

Accepted Answer

Cambridge applicants MUST take Sitting 1 in October. Cambridge does NOT accept Sitting 2 scores because interview shortlisting occurs in November. Because Cambridge conducts interviews in December, all admissions assessment scores must be delivered to colleges by November. Imperial and UCL accept either Sitting 1 or Sitting 2, but applicants applying to both Cambridge and Imperial must take Sitting 1.

Question 20

How and when do I register for the ESAT?

Accepted Answer

Registration opens in August via the official registration portal. The registration deadline for Sitting 1 is in mid-September (typically September 16). Candidates create an official candidate web account, select their preferred local test centre and appointment slot, specify the modules they intend to sit, and pay the test fee. Slots at popular test centres fill rapidly, so register as early as possible once booking opens.

Question 21

Are there test fee waivers or bursaries available for eligible candidates?

Accepted Answer

Yes. UK candidates from lower-income backgrounds, those eligible for free school meals, or those in receipt of specified government support can apply for a full fee waiver through UAT-UK prior to booking. Fee waiver applications must be submitted with supporting documentation before registering for the test. Successful applicants receive a voucher code that covers 100% of the test registration fee.

Question 22

What physical materials are provided at the official test centre?

Accepted Answer

The test centre provides a laminated spiral-bound reusable booklet (dry-wipe scratchpad) and fine-tip black dry-erase marker pens. You may not use your own pens, erasers, or scrap paper. Test centre administrators issue one standard laminated notebook consisting of several double-sided gridded/lined plastic pages. You must use only the issued marker. Test centres do not provide erasers; you are instructed not to erase with your fingers.

Question 23

What happens if my dry-wipe scratchpad booklet fills up during the exam?

Accepted Answer

You must raise your hand to request an additional booklet from the invigilator. Do not wait until you have completely run out of space; signal the invigilator with 1–2 pages remaining. Invigilators will exchange your full booklet for a clean one. Because the exam clock does not stop while the invigilator retrieves a booklet, efficient spatial management of your scratchpad is essential to prevent time loss.

Question 24

What is the recommended strategy for managing scratchpad space and handwriting?

Accepted Answer

Divide each laminated sheet into numbered quadrants or use Sub90's 2-Line method: Line 1 for Setup/Ratio invariants, and Line 2 for Factor cancellation and Option pruning. Writing out long essay-style working fills the booklet rapidly and wastes valuable seconds. Keep calculations terse: write down only the governing equation, ratio proportions, and crossed-out eliminated options (e.g. crossing out A, C, D).

Question 25

Can I take water or medication into the examination room?

Accepted Answer

Water in a clear, label-free bottle is permitted in many test centres but may need to be kept on the floor. Specific medical items or adjustments require approved accommodations prior to test day. All personal belongings (phones, watches, coats, bags, calculator, pencil cases) must be stored in test centre lockers before entering the exam room. Any unauthorized item inside the room constitutes grounds for immediate disqualification.

Question 26

Why is the time target set to 90 seconds per question?

Accepted Answer

Each 40-minute module has 27 questions. Converting 40 minutes into seconds yields 2,400 seconds; dividing by 27 questions gives approximately 88.9 seconds, rounded to a clean 90-second pacing budget per question. The 90-second threshold is the strict average time available to read the question stem, inspect diagrams or tables, perform calculations, eliminate distractors, and confirm your choice. Any question taking >120s directly starves later questions of time.

Question 27

Why do traditional A-Level classroom methods fail on the ESAT?

Accepted Answer

A-Level mark schemes award method marks for full, exhaustive algebraic working, which takes 2 to 3 minutes per problem. The ESAT only awards credit for the correct final letter choice, making rapid heuristics, dimensional analysis, and factor cancellation far more effective. Students who attempt to solve ESAT questions using standard textbook methods run out of time with 6 to 8 questions unattempted. High-scoring candidates use invariant spotting, boundary testing, and proportional ratio scaling to reach the answer in under 60 seconds.

Question 28

What should I do if I am stuck on an ESAT question past 60 seconds?

Accepted Answer

If you have not identified a viable solution path within 60 seconds, eliminate any mathematically impossible options, click your best guess, press 'V' to flag the question for review, and immediately press 'N' to move to the next question. Spending 3+ minutes on a difficult question is the number one cause of score collapse. Since all questions are worth exactly 1 mark, bank the easy and medium questions first. Flagged questions can be revisited in the final 3–4 minutes if time permits.

Question 29

How should I use the flag for review feature and option elimination?

Accepted Answer

Always select an option before flagging a question. Even if unsure, eliminating two obvious distractors raises your guessing odds from 20% to 33% or 50%. Leaving a question blank with the intention of returning to it is dangerous: if time expires, you lose the opportunity to guess. By locking in a provisional answer and flagging it, you guarantee a baseline score while preserving the option to refine it later.

Question 30

How does Sub90's 75-Archetype and 6-Step Lesson methodology train candidate speed?

Accepted Answer

Sub90 reverse-engineers the entire ESAT syllabus into 75 Master Archetypes. Each archetype features a 6-Step active-recall topic lesson teaching the fast heuristic and distractor forensics before putting you on the 90-second countdown clock. Rather than endless passive reading, candidates drill the exact pattern-recognition reflexes required on exam day. You learn to spot the 8 examiner distractor traps, practice with the 180 non-calculator drills in the Speed Dojo, and review errors in the spaced-repetition Mistake Bank.
