ESAT preparation guide

ESAT test day, from arriving at the centre to the final module

Q: Can I take a calculator into the ESAT?

No. The official ESAT page states that "you will not be able to use a calculator or dictionary", the specification says "Calculators may NOT be used", and the FAQ confirms calculators are not permitted in either the ESAT or the TMUA. Dictionaries are out too. The official description of your workstation makes no mention of a formula sheet either, so prepare on the assumption that there is none and that formulae and standard conversions have to be memorised. Practise with the calculator off, and give particular attention to units and orders of magnitude.

Q: Is it true that candidates in China can only sit the ESAT on one or two days?

Yes. For 2027 entry, candidates in mainland China, Hong Kong and Macau can sit the ESAT only on 12 or 13 October 2026 and on 6 January 2027, while candidates elsewhere may sit on any day of the 12 to 16 October and 4 to 8 January windows. UAT-UK attributes the restriction to reports in October 2024 of candidates attempting to obtain and sell test content without authorisation, which is why the test now runs on two days in October and one in January in those territories. In practice: book as soon as the window opens, and treat the date as immovable when arranging travel.

Q: How early should I arrive, and what happens if I am late?

You should arrive 30 minutes ahead of your scheduled sitting. Arriving more than 15 minutes late may mean you are refused entry, and if that happens your test fee is forfeited. The fee is set by the location of the centre rather than your nationality or residence: £78 in the UK and the Republic of Ireland, £133 elsewhere. If you are sitting in mainland China, Hong Kong or Macau the consequence is heavier, because you may sit only once per cycle and only one or two dates exist; the official pages do not say whether a refused entry can be rebooked, so plan as though it cannot.

Q: Are there breaks between modules, and how long is the whole thing?

There are none. The official wording is "there are no breaks between modules or papers of your test". Most candidates take three modules and the ESAT is 120 minutes long for them, so it is two continuous hours. Each module is 40 minutes and 27 multiple choice questions, and each is separately timed: finishing early does not carry time into the next module. Deal with water, food and the toilet before you start, and practise in back-to-back blocks rather than always drilling one isolated module.

Q: What do they give you for rough work, and can I bring my own paper?

The centre provides an erasable surface and a pen; you neither need nor should bring your own. You can request a replacement at any point during the test by raising your hand. One caveat worth knowing: the official pages are not consistent about what it is. The specification calls it an erasable booklet, the test day page an erasable notebook, and the FAQ a whiteboard and pen. Treat the form as unsettled and do not build a working method that only functions on one of them. Nothing official says the clock pauses while you swap, so assume it does not.

Q: Can I discuss the questions with friends afterwards?

No. The rule is that "you must not share or discuss the test with anyone else", which covers comparing answers in a group chat, writing up a reconstruction, posting to ask about a specific question, and describing content on social media. The rule carries more weight than it used to: reports in October 2024 of candidates attempting to obtain and sell test content led directly to the ESAT being restricted to two days in October and one in January in China, Hong Kong and Macau. After the test there is nothing to do but wait for results, which arrive in your UAT-UK account roughly four weeks later.

Q: Can I change my modules or my test date after booking?

Not directly. UAT-UK states that modules "cannot be changed without cancelling and re-booking your test", so check them line by line against your course requirements while you are booking. The date sits at the same booking level, and if you are sitting in mainland China, Hong Kong or Macau there are only one or two dates to move between anyway. One harder rule sits above all of this: you may sit each test only once per admissions cycle, the 2027 entry cycle includes both the October 2026 and January 2027 sittings, and any attempt to register or sit a second time within the cycle is treated as misconduct, including booking under a second UAT-UK account.

The ESAT is a computer-based test taken at a Pearson VUE test centre. Most candidates sit three modules on the day: 40 minutes and 27 multiple choice questions each, separately timed, with no breaks in between, which UAT-UK describes as 120 minutes long for most candidates. On the desk you get a PC, a keyboard and mouse, and an erasable surface with a pen for rough work. Calculators and dictionaries are prohibited. If you are sitting in mainland China, Hong Kong or Macau, one further rule outranks all of the above: the ESAT runs there on only one or two set days, while candidates elsewhere can pick any day in the window. This page walks through the day in order, covering when to arrive, how late is too late, how to pace two continuous hours, and what you are not allowed to do once you have finished.

ESAT Test Day at a Glance

Format: Computer-based at a Pearson VUE centre; three modules and 120 minutes for most candidates
Modules and timing: 40 minutes and 27 multiple choice questions per module, each timed separately, with no breaks
Arrival and lateness: Arrive 30 minutes early; more than 15 minutes late may mean refused entry and a forfeited fee
Dates in China, Hong Kong and Macau: 12 or 13 October 2026 and 6 January 2027; candidates elsewhere pick any day of the window
On the desk: A PC, keyboard, mouse and an erasable surface with a pen; no calculator and no dictionary

All of the above follows UAT-UK's official pages and the ESAT content specification. Results appear about four weeks after the sitting: 16 November 2026 for October and 8 February 2027 for January, in the 2027 entry cycle.

In short

In mainland China, Hong Kong and Macau the ESAT runs only on 12 or 13 October 2026 and 6 January 2027, while candidates elsewhere can use any day of the window.
Arrive 30 minutes early. Arriving more than 15 minutes late may cost you entry, and the fee is forfeited.
Your desk holds a PC, keyboard, mouse and an erasable surface with a pen. No calculator, no dictionary, and no formula sheet mentioned in the official description.
Each 40-minute module is timed separately, spare time never carries over, and there are no breaks between modules.
Discussing or sharing test content afterwards is prohibited. Results land about four weeks later, module by module, with no appeals.

Part 1 of 3

Sections 01 to 04

Test day is one sitting, on one machine, at one centre

The ESAT is a computer-based test taken at a Pearson VUE test centre, not something you sit at home. The official description of the workstation is plain enough: a PC, a keyboard and a mouse, plus an erasable writing surface and a pen supplied by the centre. How many modules you face depends on the course you have applied to.

Format

Computer-based, at a Pearson VUE test centre

Not something you sit at home on your own machine

Compulsory module

Everyone sits Mathematics 1

The rest follow the requirements of the course you applied to

What most candidates face

Three modules, which UAT-UK puts at 120 minutes

In UAT-UK's words, the ESAT "will be 120 minutes long for most candidates"

Each module

40 minutes, 27 multiple choice questions

A few courses ask for two modules only: MEng Design Engineering at Imperial takes Mathematics 1 plus Mathematics 2, so 80 minutes

The phrase that shapes the whole day is "separately timed". The specification is explicit: finish a module early and that time is not carried over to the next one. There is no strategy of racing through your strongest module to bank minutes for the hardest one, because the minutes do not travel. Anything you save has exactly one use, which is checking the module you are already in.

In mainland China, Hong Kong and Macau you get one or two dates, not a week

If you are sitting in mainland China, Hong Kong or Macau, this is the single most important line on the page. For 2027 entry the ESAT runs there only on 12 or 13 October 2026, and on 6 January 2027. Candidates everywhere else can sit on any day of the window.

	October window	January window
Mainland China, Hong Kong, Macau	12 or 13 October 2026	6 January 2027
Everywhere else	12 to 16 October 2026	4 to 8 January 2027

UAT-UK gives the reason without softening it. Following reports in October 2024 of candidates attempting to obtain and sell test content without authorisation, the ESAT and TMUA now run on only two days in October and one day in January in China, Hong Kong and Macau.

Consequence 1: booking

Book the moment the window opens

Seats are compressed into a couple of days, so do not drift towards the deadline

Consequence 2: clashes

The clash has to be solved on the other side

You cannot move your date to dodge a school exam, an olympiad or another admissions test

Consequence 3: missing the slot

More than 15 minutes late and you may be refused entry, with the fee forfeited

The other rule fixed in writing: you may sit each UAT-UK test only once per admissions cycle

Whether you could book another day in the same window after being refused entry is not something the official pages address, and with one or two dates available the safe assumption is that you could not. Plan travel, accommodation and the school absence around a fixed date from the day you book, not in the week before.

What is actually on the desk, and what the official pages disagree about

The official test day page says you will find "a PC, keyboard and mouse as well as an erasable notebook and pen for rough work", and that you "can request new sheets at any point during your test by raising your hand".

The content specification calls it

an erasable booklet

The test day page calls it

an erasable notebook and pen

The FAQ calls it

a whiteboard and a pen

What all three agree on

A wipeable writing surface, supplied by the centre, replaceable on request, not yours to take away

You neither need nor should bring your own

One more thing the official pages do not address, which you should assume conservatively: nothing says the clock pauses while you raise your hand for a fresh surface. Plan as though it keeps running.

That argues for two habits in practice: work in defined areas of the surface rather than sprawling across it, and park the key intermediate quantities somewhere you can find them again, so that a check does not mean redoing the whole question. And since the official pages have not settled whether it is a bound booklet or a board, do not build a working method that only functions on one of them.

No calculator, no dictionary, and no formula sheet

Calculator

Not permitted

Stated on the ESAT page, in the FAQ and in the specification, which says "Calculators may NOT be used"

Dictionary

Not permitted

The ESAT page: "You will not be able to use a calculator or dictionary"

Formula sheet

Absent from the official description of your workstation

Prepare on the assumption that there is none

Units and prefixes

The specification expects SI prefixes from nano to giga

Along with negative index notation such as m s^-1

The dictionary ban costs more than it looks if English is not your first language. Subject vocabulary has to be secure before you arrive, because there is no lookup of any kind in the room: apparatus names, biological structures, the verbs used to describe a chemical procedure. The fix is not a vocabulary list the night before. It is reading and reasoning in English from the start, so that no translation step sits between reading a question and starting it.

Trigonometric identities, log rules, mechanics and electricity relationships and the standard unit conversions all have to come from memory. Without a calculator, magnitudes and units are where marks leak fastest, so practise with the calculator switched off: hand arithmetic, cancelling, and estimating to the right order of magnitude.

Part 2 of 3

Sections 05 to 08

Thirty minutes early, and the fifteen-minute cliff edge

30 minutes

How early UAT-UK says to arrive at the centre

15 minutes

Arrive later than this and you may be refused entry

£133

The fee outside the UK and Ireland, forfeited if you are refused entry

£78

The fee at centres in the UK and the Republic of Ireland

The fee depends on where your test centre is, not on your nationality or where you live: a British candidate sitting abroad pays £133, an overseas candidate sitting in the UK pays £78. Anyone sitting at a centre in China therefore falls in the £133 band, and that is the sum at risk, since in UAT-UK's own words "your test fees will be forfeited".

Read this alongside the previous section and the stakes are obvious. If you are sitting in mainland China, Hong Kong or Macau there are only one or two dates to begin with, and nothing official tells you whether a refused entry can be rebooked, so treat it as though it cannot.

Plan the journey for the worst case. Test centres may sit inside office buildings, so finding the right entrance, the right floor and a working lift belongs in the timing, and a reconnaissance trip the day before is not overkill. As for identification and booking documentation, requirements vary between centres, so follow the confirmation and instructions you were sent rather than a friend's account of last year.

No breaks between modules, so the two hours run straight through

The official line is one sentence: "There are no breaks between modules or papers of your test." For most candidates that means 120 minutes straight through.

01Before

Everything physical happens before you start

Water, food and the toilet all belong to the time before the appointment, because there is no built-in pause between modules to catch your breath.

02Block 1

First module, 40 minutes

Twenty-seven multiple choice questions, timed on its own. Finish early and the spare minutes do not carry into the next module.

03Block 2

Second module, 40 minutes

No break in between, you go straight on. The official pages do not state the order the modules appear in, so there is no point agonising over sequence.

04Block 3

Third module, 40 minutes

For most candidates this is where the 120 minutes end. Courses that require only two modules finish after the second block, at 80 minutes.

This is where more preparation goes wrong. If every revision session is a single 40-minute module, the third module on the day will be the first time you have ever worked in that state, and it may well be the one your course cares most about. So build in at least one full run per week: 40 minutes, no stop, straight into the next module. What you are training is the ability to hold reading accuracy for two continuous hours, and to bring the same checking discipline to the third sitting as to the first.

Twenty-seven questions in forty minutes: three decisions that matter

That is under 90 seconds a question on average. At that tempo the score is decided by three in-the-moment decisions.

Multiple choice questions in each module

Under 90 seconds

Average time available per question

1 mark

Each correct answer, with no deduction for a wrong one

Decision 1: leave nothing blank

When time is called there should be no unanswered question on your screen

UAT-UK says plainly that "it's worth attempting all questions"; this is not gambling but free expected value written into the rules

Decision 2: cut losses on time

Once a question has eaten its budget without a clear route, commit to the most defensible option and move on

The specification says the test is designed to be challenging in order to differentiate between able applicants, including those with the highest possible school grades, so getting stuck is the design working

Decision 3: learn the interface first

Whether you can flag questions or move back and forth is a property of the software, and the official preparation material is the reliable source

UAT-UK states that all necessary preparatory materials are free of charge to all candidates; working through them beats anyone's recollection

Four things fixed at booking that test day cannot fix

The four things below are settled at the moment you book, and test day offers no way to undo any of them.

Module selection

Cannot be changed without cancelling and re-booking

If one of your ESAT-requiring courses names compulsory modules and another leaves the choice open, the named ones win; register without them and that application may be invalid

Number of sittings

Once per admissions cycle

The 2027 cycle contains both the October 2026 and January 2027 sittings and you may sit once across the pair; a second attempt counts as misconduct, including booking under a second UAT-UK account

Which sitting you take

Most Cambridge and Oxford applicants must sit in October

The exceptions UAT-UK names are mature applicants to a Cambridge mature college with a January deadline and Oxford's Astrophoria Foundation Year; the FAQ adds that a course with no UAT-UK requirement leaves you free to sit in January

Applicants elsewhere

Free to choose the sitting

UAT-UK states there is no advantage to either session

III

Part 3 of 3

Sections 09 to 10

After you finish: do not compare answers, do not post recollections

The rule is one line and it is not decorative: "You must not share or discuss the test with anyone else." No comparing answers in a group chat, no writing up a reconstruction, no posting to ask what the right option was, no describing content on social platforms.

Section two explains why this matters more than it used to. Reports in October 2024 of candidates attempting to obtain and sell test content led directly to the ESAT being offered on only two days in October and one in January in China, Hong Kong and Macau. The cost of tightened security has already been paid once, collectively, by everyone sitting in those territories.

When results arrive

About four weeks after the sitting, in your UAT-UK account

For 2027 entry: 16 November 2026 for October and 8 February 2027 for January

How scores are reported

Module by module, on a scale from 1 (low) to 9 (high) to one decimal place

No pass mark, and UAT-UK publishes no grade boundaries

Delivery to universities

Matched course by course against your UCAS application and sent automatically to institutions whose courses require the test

Candidates cannot choose which institutions see a score

Appeals

UAT-UK does not accept appeals of test scores

Which means the useful thing to do on the evening of the test is to turn back to your personal statement and interview preparation, not to reconstruct the paper from memory.

A checklist for the last 72 hours

01Item 1

Re-check the booking

Date, time, centre address, and above all that the modules you selected match what your course requires. A wrong module cannot be fixed on the day.

02Item 2

Work backwards from arrival

Start from arriving 30 minutes early, then add slack on top. Time spent finding the right door and the right floor of an office building is routinely underestimated, and if you are travelling, staying near the centre removes an entire category of risk.

03Item 3

Do one last full run

All your modules, 40 minutes each, no stopping between them, calculator switched off. The purpose is calibrating pace, not learning content.

04Item 4

Practise arithmetic by hand

Unit conversions, cancelling, order-of-magnitude estimates. This is the first thing to fall apart without a calculator and the easiest thing to shore up.

05Item 5

No new material the day before

Fresh questions manufacture anxiety and return almost nothing. Spend the time going back through your own error log and confirming what you do when each type appears.

06Item 6

Take what your confirmation tells you to take

Identification and booking documentation requirements differ between centres, so read your own instructions; storage of personal items follows centre procedure, and reading the notice beforehand beats asking at the desk.

07Item 7

Leave when you finish

No discussion of the paper in any form, including the tempting compromise of talking about difficulty rather than content.

If you want timed back-to-back runs at the real tempo, the practice and mock modules on FrontierVUE can be timed in 40-minute blocks and run three in a row, which is the one thing this page keeps returning to: there is no break between modules.

FAQ

Frequently asked questions

Can I take a calculator into the ESAT?

No. The official ESAT page states that "you will not be able to use a calculator or dictionary", the specification says "Calculators may NOT be used", and the FAQ confirms calculators are not permitted in either the ESAT or the TMUA.
