Key points

  • Most Cambridge and Oxford applicants must sit in October, so the January ESAT is mainly for applicants to other universities, such as Imperial and UCL.
  • Booking opens on 26 October 2026 and closes on 21 December 2026, and bursary and access-arrangement requests have earlier deadlines.
  • Eleven weeks from late October leaves time to check your modules, sit timed modules early, work on your biggest gaps and sit all three modules together twice.

Who sits the ESAT in January?

The January ESAT is mainly for applicants to universities other than Cambridge and Oxford. UAT-UK says most Cambridge and Oxford applicants must sit in October, while applicants to other universities can usually choose either sitting, and there's no advantage to either one.

The ESAT (Engineering and Science Admissions Test) is a computer-based test with five modules: Mathematics 1, Mathematics 2, Physics, Chemistry and Biology. Everyone takes Mathematics 1, and most courses ask for two more. Each module has 27 multiple-choice questions in 40 minutes, and you can't use a calculator.

On UAT-UK's course list for 2027 entry, courses outside Cambridge and Oxford that use the ESAT include Imperial's Mechanical Engineering and Physics, and UCL's Electronic and Electrical Engineering. Requirements differ between courses at the same university, so check each course page. UCL's Mechanical Engineering, for example, uses the TARA instead.

Who has to sit in October instead?

Most Cambridge and Oxford applicants must take the October sitting. The exceptions are narrow. Cambridge mature applicants applying to a mature college with a January deadline may sit in January, and applicants to Oxford's Astrophoria Foundation Year may use either sitting.

You can sit the ESAT once in an admissions cycle. If you sat it in October, January isn't a second attempt. If one of your courses is at Cambridge or Oxford, check its deadline before you plan around January.

When is the January 2027 ESAT and how do you book?

The January sitting is from 4 January 2027 to 8 January 2027. Booking opens on 26 October 2026 and closes on 21 December 2026.

Booking has two stages. First you create a UAT-UK account, then you book a date, time and test centre through Pearson's booking system. Choose your modules carefully, because you can't change them at the test centre. Changing them later means cancelling and rebooking, if appointments are still free.

If you need a bursary or access arrangements, apply first and wait for the decision before you book. Both have deadlines earlier than the booking deadline, and UAT-UK can't refund a fee you paid before your bursary was confirmed. The exact dates are on UAT-UK's deadlines page.

Weeks one to three: modules and first timed papers

Week one: open the course page for each university and write down the ESAT modules it asks for. Download the ESAT specification and go through the topics for your three modules, marking each one secure, rusty or not yet taught at school.

Week two: book your test once booking opens. Then sit a full Mathematics 1 module under real conditions, which means 40 minutes, no calculator, no pausing and your phone in another room. When you mark it, note which questions took too long and which right answers were guesses, as well as the score.

Week three: sit one timed module in each of your other two subjects. Then sort the mistakes from all three papers into four groups: things you didn't know, methods that were too slow, questions you misread, and time lost on a question you should have left. That list decides the next three weeks.

Weeks four to seven: working on the gaps

Weeks four to six are for the biggest gaps your first papers showed. Give most sessions to one topic or one kind of mistake. If concentration questions keep going wrong, do six short ones without a calculator, then meet the same idea a week later in a mixed set where it isn't labelled.

A topic you haven't been taught needs a proper lesson from a textbook or a teacher before you practise it. Once a week, do a short timed set that mixes questions from across a module, so you get used to spotting the topic for yourself.

Week seven: go back to full 40-minute modules. Use a flagging rule every time. If you've spent about a minute on a question and still can't see how to start, pick the most likely answer, flag it and move on. A wrong answer doesn't lose you a mark, so never leave a question blank.

Weeks eight to ten: all three modules together

In week eight, sit all three modules in one session, as close to the real test as you can make it. Each module is timed separately and any time you save doesn't carry over to the next one, so practise starting each module fresh.

Week nine: fix the few things that sitting showed. If your last module had more arithmetic mistakes than the first, the answer may be sleep, food or a calmer flagging rule, and more revision won't help. Check your booking is confirmed well before booking closes on 21 December 2026.

Week ten falls over Christmas. Plan around the days you'll really work, fit in a second full sitting if you can, and keep the other sessions short.

Week eleven: the days before the sitting

Don't try to learn new topics now. Go back over the mistakes you keep making, and do short timed sets so your pacing stays familiar.

Try the Pearson sample test on a desktop computer so the on-screen software isn't new on the day. Read UAT-UK's test-day guidance and your booking confirmation, check the photo ID rules and plan your route to the test centre.

If you're starting later than late October, shorten weeks four to six and keep the full sittings.

Which materials should you use?

Start with the official material. The specification and the ESAT Guide tell you what can be tested, and the specimen and practice tests show you the style of question. UAT-UK also links older ENGAA and NSAA papers, with notes on which questions fall outside the current specification. There aren't many, so mark each one carefully before you start the next.

After that you'll need original questions written to the specification. Noetra's mocks are all original, and we're not affiliated with UAT-UK, Pearson VUE or any university. The free ESAT paper on this site is a full Mathematics 1 module, and the score it gives is our own estimate, not an official result.

Questions students ask

Can I sit the ESAT in January if I'm applying to Cambridge?
Usually not. Most Cambridge and Oxford applicants must sit in October. Cambridge mature applicants applying to a mature college with a January deadline are an exception, so check your course and college pages.
Is the January ESAT harder than the October one?
UAT-UK says there's no advantage to either sitting. Both use the same content specification, which covers the October 2026 and January 2027 sittings.
Can I sit the ESAT in October and again in January?
No. You can sit the ESAT once in an admissions cycle, so January isn't a second attempt.
How long do I need to prepare for the January ESAT?
There's no fixed answer. Eleven weeks from late October gives you time for the plan above if you've been taught most of the content. If there are topics you haven't covered at school, start with those.
When does booking close for the January ESAT?
Booking closes on 21 December 2026. Bursary and access-arrangement deadlines are earlier, so check UAT-UK's deadlines page if you need either.
