TMUA October vs January: Which Sitting to Take

There are two TMUA sittings in each admissions cycle, October and January, and you can only take the test in one of them. For 2027 entry the October sitting ran from 12 to 16 October 2026 and has finished, with results due on 16 November 2026. That leaves January 2027 as the only sitting still open this cycle, and for most readers the real question is now whether to sit in January or wait for October 2027. This guide sets out who can use January, why Cambridge and Oxford need October, and how to decide.

The two sittings and their dates

For 2027 entry the TMUA runs in two windows, and you choose one:

Both sittings test exactly the same thing in exactly the same format: two papers, multiple choice, no calculator, marked on the same 1.0 to 9.0 scale. The test does not change between October and January, and there is no scoring advantage to either window. UAT-UK equates every version of the test onto one scale and uses the same scaling for both sittings, so a 6.5 in January means the same as a 6.5 in October. The January group does score lower on average (in the 2025-26 cycle its median was 3.6, against 4.5 in October), but because both sittings share one scale, that reflects who sat in each window, not how hard the paper was. There is no easier paper to hunt for, and no reason to pick a sitting for anything other than which universities you are applying to and when.

One group does not get the full windows above. Candidates sitting in mainland China, Hong Kong and Macau can take the TMUA only on 8 January in the January sitting (it was 15 or 16 October in October); the dates are assigned rather than chosen. The reasons and the practical consequences are in TMUA dates in Hong Kong, China and Macau.

The January booking deadline is two weeks ahead of the test window. Booking opened on 28 October 2026 at 3pm GMT and closes on 21 December 2026 at 6pm GMT, and you register through your own UAT-UK account and a Pearson VUE test centre, not through your university. There is no late entry, and for 2027 entry there is no sitting after January.

Who can use the January sitting

January is open to every applicant whose universities accept it, which is every TMUA university except Cambridge and Oxford for standard entry. As of October 2026:

• Imperial accepts either sitting and says only your first score is considered.
• LSE accepts either sitting and says there is no advantage to either. It encourages October only because October has the widest choice of slots and locations.
• Warwick accepts either sitting, also says there is no advantage to either, and uses one score per cycle.
• Durham lets applicants choose between the October and January sittings.
• UCL (Economics) falls under UAT-UK's rule that applicants to every institution other than Cambridge and Oxford can sit on either date.
• Cambridge and Oxford require October for standard applicants. The only exception is applicants to a Cambridge mature college (Hughes Hall, St Edmund's or Wolfson) applying in its January round. Oxford has no January route for the TMUA.

January is a mainstream route, not a special case: in the 2025-26 cycle, 40% of all TMUA candidates sat in January (6,407 of 16,092). Requirements still change from year to year, so confirm on each university's course page that your course accepts January before you book.

If you are still working out where you are applying, our guide to which universities require the TMUA lays out who asks for it, and the course-specific pages for the TMUA at Cambridge and the TMUA at Oxford cover exactly what each expects.

If you sat in October 2026

You are done for this cycle. UAT-UK allows one sitting per admissions cycle, and Imperial, LSE and Warwick each say they use only one score, so January is not a second attempt. Your result arrives on 16 November 2026 and goes automatically to the universities on your UCAS application that use the test. Our results day guide covers what to expect and what to do with the number.

If you have not sat it yet: January 2027

If you are applying for September 2027 entry and have not sat the TMUA, January 2027 is your last chance this cycle. It is the right choice if every TMUA university on your list accepts it, and for applicants who are not applying to Cambridge or Oxford for standard entry, it will.

A few practical points:

• Your UCAS application does not wait for the test. The UCAS equal consideration deadline for most courses is 13 January 2027 at 6pm, and January results arrive on 8 February. You apply first and the score follows. Warwick's Mathematics admissions, for example, set their final TMUA threshold around April, after reviewing the applications received by the January deadline.
• Book early in the booking window. Booking runs from 28 October to 21 December, and the deadline falls just before Christmas. UAT-UK advises booking as early as possible, because the convenient slots and centres go first.
• Plan your revision around the holidays. The test window is 4 to 8 January, the first week of spring term in most UK schools, so most of your final preparation happens over the Christmas break.

If one of your choices is Cambridge or Oxford for standard entry and you did not sit in October, January does not replace it. Check directly with the university what that means for your application.

If you will apply in autumn 2027: wait for October 2027

If you are in Year 12 now, or you plan to apply next autumn (for example after a gap year), your sitting belongs to the 2028 entry cycle: October 2027, or January 2028 if none of your universities needs October.

There is no point sitting in January 2027 as a practice run. A score belongs to one admissions cycle: UAT-UK says earlier scores are not visible to you or to universities in a later year, and Warwick says it only accepts a TMUA taken in the same academic year as the UCAS application.

UAT-UK has not yet published dates for the 2028 entry cycle. This cycle it opened accounts on 1 June 2026 and booking on 20 July 2026, with the test in mid-October, so expect a similar pattern next year, and confirm it on the official deadlines page.

Next cycle: why October is still the default

For anyone planning the 2028 entry cycle, October remains the safer default, for the same reasons it was this year:

• It keeps Cambridge and Oxford open. They require October for standard applicants, and every other TMUA university accepts it too, so one test covers every option. Choosing January rules out a standard Oxbridge application, and you cannot switch once you have committed to a sitting.
• Your score arrives earlier. October results come out in mid-November, while January results come out in February. Warwick, for example, starts releasing Mathematics decisions from November, after the October results.
• You get the widest choice of slots. LSE and Warwick both encourage the first sitting for exactly this reason.
• It frees up your winter. The test is behind you before mock exams and the busiest stretch of Year 13, rather than hanging over the Christmas holidays.

January makes sense next cycle if you are certain you are not applying to Cambridge or Oxford for standard entry, every university on your list accepts January, and you want the extra weeks of preparation. That can be the right trade if you started late or want to spend the autumn on your application first. Be honest about whether those weeks will be used well, or whether they just push the test into the busiest part of your year.

You only get one shot, so prepare for it

Because you sit the TMUA once per cycle and cannot resit, the window you choose is also the window you need to be ready for. That makes the preparation question inseparable from the timing one.

If you are sitting in January 2027, your preparation runs through November and December, with full timed papers before the holidays end. If you are aiming for October 2027, you have the time to build up steadily, finishing with timed past papers in late September. Either way, the test rewards familiarity with its style far more than last-minute cramming, so the earlier you start, the calmer the run-in. Our how to prepare for the TMUA guide turns this into a week-by-week plan you can map onto whichever sitting you pick.

The bottom line: if you are applying for 2027 entry and have not sat the TMUA, book the January 2027 sitting before 21 December, as long as your universities accept it. If you are applying in autumn 2027, plan for October 2027.
