TMUA for Oxford: The New Maths & CS Test (MAT Replaced)

If you are applying to Oxford for Maths or Computer Science, the admissions test on your to-do list has changed. For 2027 entry, Oxford has retired the long-running MAT and now uses the TMUA instead, and that swap changes what you sit, how it is marked, and how you should be revising right now.

This guide walks through exactly what happened, which Oxford courses are affected, how Oxford actually uses the score, what is genuinely different for anyone who had been grinding MAT papers, and the score range to aim for in one of the most competitive applicant pools in the country.

What changed, and why it matters

For nearly two decades, Oxford screened its mathematical applicants with the MAT (the Mathematics Admissions Test), which ran from 2007 to 2025. In January 2026, Oxford announced that the MAT is discontinued and that, from the October 2026 sitting onward, Oxford applicants will take the TMUA (the Test of Mathematics for University Admission) instead.

That is a bigger shift than a simple name change. The MAT was an Oxford-specific paper. The TMUA is a shared admissions test run by UAT-UK (a joint venture between the University of Cambridge and Imperial College) and delivered at Pearson VUE test centres. So Oxford is moving from its own bespoke exam to a national test that Cambridge, Imperial, LSE, Warwick and others already use. In practice, the Oxbridge maths and computer science cohorts now sit the same admissions test, which means the field taking the TMUA this cycle is larger and stronger than ever.

Why does the change matter to you specifically? Because the format, the marking, and the skills under examination are different enough that you cannot simply repurpose your MAT preparation and hope it transfers. The good news: the underlying mathematics is the same A-level-and-a-bit foundation, so the work you have already done is far from wasted. You just need to retrain how you apply it.

Which Oxford courses now use the TMUA

The TMUA requirement applies to Oxford's mathematical degrees. For 2027 entry, you will sit the TMUA if you are applying for:

• Mathematics, including its joint courses (such as Maths with a second subject)
• Computer Science, including Computer Science joint honours

In short, if your Oxford course has "Mathematics" or "Computer Science" in its title, assume the TMUA is part of your application and check the specific course page to confirm. Courses outside this mathematical family use their own admissions processes and are not affected by this change. The point worth internalising is that Oxford Computer Science is now assessed through a mathematics-and-reasoning test rather than a separate computing paper, so strong, fluent problem-solving in pure maths and logic is what is being measured.

How Oxford uses your TMUA score

This is where applicants most often get the wrong idea, so it is worth being precise. Your TMUA score is one input into Oxford's shortlisting decision, not a pass-or-fail gate with a published cut-off.

Oxford does not release an official minimum TMUA score. Instead, admissions tutors read your application as a whole: predicted and achieved grades, your personal statement, your school reference, the TMUA result, and, for shortlisted candidates, the interviews. The test does a specific job: it helps tutors decide whom to invite to interview from a very large field of strong applicants, and it gives a common, externally marked data point that sits alongside the more subjective parts of your file.

A few consequences follow from that:

• A high score strengthens your case for an interview but does not guarantee one, and it does not by itself secure an offer. The interviews carry real weight.
• A middling score is not automatically fatal, especially if the rest of your application is outstanding, but at Oxford maths and CS the competition is fierce enough that you do not want to be relying on the benefit of the doubt.
• Because there is no fixed threshold, you should aim to be comfortably inside the competitive range rather than chasing a single magic number.

What is different if you were preparing for the MAT

If you have already worked through MAT papers, here is the honest reckoning of what carries over and what does not. The table below lays out the contrast.

Three differences deserve emphasis.

First, the TMUA is multiple choice, not long-form written proof. With the MAT you earned method marks for a partially correct argument. On the TMUA only your selected answer counts, so a small slip that would have cost you a mark or two on the MAT can cost you the whole question here. Precision and answer-checking matter more than ever, and there is a real skill in working backwards from the options or testing them rather than grinding out a full solution every time.

Second, the TMUA is split into two papers and Paper 2 changes the game. Paper 1 (Applications of Mathematical Knowledge) is pure-maths problem solving that will feel broadly familiar to a MAT student: roughly AS-level content, but harder and more indirect. Paper 2 (Mathematical Reasoning) is the one to respect. It tests logic, necessary and sufficient conditions, counterexamples, and your ability to spot the single invalid step inside an otherwise convincing proof. This style of thinking is barely touched at A-level and the MAT did not isolate it the way Paper 2 does. If you have been preparing for the MAT, this is the area where you are most exposed and where focused practice pays off fastest.

Third, the marking is different in a way that should shape your exam-day behaviour. The TMUA scores each paper from 1.0 to 9.0 in 0.1 steps, awarding one mark per correct answer and zero for a wrong or blank one. Crucially there is no negative marking, so you should answer all 40 questions: an educated guess on a hard item is strictly better than leaving it blank. The MAT did not reward blind guessing in the same way.

What score should you aim for at Oxford?

Let me be careful here, because the honest answer is that Oxford publishes no official cut-off and any specific number you see quoted as a "minimum" is someone's inference, not policy. What follows are competitive ranges, not thresholds.

On the 1.0–9.0 scale, a score around 5.0 is roughly the average across all candidates sitting the test nationally. But Oxford maths and computer science draw one of the strongest applicant pools in the country, so the average TMUA candidate is not the comparison you care about. To stay genuinely competitive for an interview, you should be aiming meaningfully above the national average: in broad terms, a score around 6.5 or higher keeps you in the conversation, and the top of the Oxford field tends to sit above 7. Scores in the exceptional band, 7.5 and up, are rare and mark you out, but they are a target to stretch toward rather than a requirement.

Treat these as directional. A 6.4 does not end your application and a 7.0 does not guarantee an offer, because the score is only one part of the picture. The sensible goal is to push your practice scores comfortably into that upper band so that the TMUA is a strength on your file rather than a question mark. Our TMUA score requirements guide explains how the scale is built and what each band tends to represent.

Here is a real Paper 1 question at roughly the level you should be training toward. Have a go before you read the solution:

Key dates: Oxford applicants must sit in October

One logistical point that trips people up: Oxford applicants must take the TMUA in the October sitting. There is a separate January sitting, but it is reserved for mature and Foundation-Year applicants, so for the standard Oxford route October is your only window.

For the 2026 sitting (2027 entry), the deadlines are:

• Registration and booking open: 20 July 2026
• Access-arrangements deadline: 14 September 2026
• Booking deadline: 28 September 2026 (6pm BST)
• Test window: 12–16 October 2026
• Results released: 16 November 2026

You book and sit at a Pearson VUE test centre. The fee is £78 for candidates in the UK and the Republic of Ireland, and £133 for international candidates. Put the booking-deadline date in your calendar now: it falls in late September, in the thick of UCAS season, and it is an easy one to let slip past.

How to prepare for the switch

If you are pivoting from the MAT, here is a practical order of operations.

1. Relearn the format first. Do a couple of full official papers under time (75 minutes, 20 questions each, no calculator) just to feel the multiple-choice rhythm and the two-paper structure. The mathematics will feel familiar; the format will not.
2. Pour your energy into Paper 2. This is the biggest delta from MAT preparation. Drill necessary-versus-sufficient conditions, building and breaking proofs, finding counterexamples, and identifying the flawed line in a proof. These are learnable skills, and they reward deliberate practice more than raw talent.
3. Train your answer-checking and option-testing. Because only the final answer scores, practise verifying results quickly and using the answer options to your advantage rather than always solving from scratch.
4. Use the official past papers. UAT-UK provides a specimen paper plus the full 2016–2023 papers for free, and there is no better source for calibrating to the real style. Our companion guide on TMUA past papers explains how to get the most out of them.
5. Build the reasoning habit with spaced repetition. Paper 2's logic patterns stick when you revisit them over time rather than cramming. Spacing your review of the trickier question types is far more effective than a single weekend blitz.

The deepest preparation comes from understanding why the right answer is right and, just as importantly, why each trap option is tempting. To see the difference between Paper 1's problem solving and Paper 2's reasoning in detail, read our breakdown of Paper 1 versus Paper 2.
