Quick answer
The MAT is gone: Oxford and Imperial now use the TMUA, with the MAT discontinued after 2025. The TMUA is two 75-minute, all-multiple-choice papers with no calculator, sat on screen, unlike the MAT's longer written questions, so old MAT material only partly transfers. CrackTMUA retunes you for the TMUA format with 400+ questions and 18+ mocks. How Oxford uses the TMUA.
"TMUA vs MAT" used to be a genuine choice for maths applicants. It no longer is. Oxford has retired the MAT and adopted the TMUA, so for almost everyone the question is not which test to pick but how the test you now sit differs from the one it replaced. This guide explains what the MAT was, what exactly changed, and how the two tests compare in format, difficulty and style, so that if you stumble on old MAT material you know precisely what is still useful and what to leave alone.
Key fact
If you are applying to Oxford for Maths or Computer Science for 2027 entry, your test is the TMUA, not the MAT. The MAT is discontinued. Old MAT papers are no longer the right preparation, and treating them as if they were is the most common and costly mistake we see.
What the MAT was
The MAT, the Mathematics Admissions Test, was Oxford's own admissions paper for Maths and Computer Science. It ran from 2007 to 2025, nearly two decades, and developed a distinctive house style of its own: a small set of long, open-ended problems that you had to crack from scratch and write out in full.
It was an Oxford-specific test. Unlike a shared national assessment, the MAT existed to screen one university's applicants, and its questions were built around the kind of sustained, proof-flavoured problem-solving Oxford tutors wanted to see. That made it excellent training for Oxford interviews, but it also meant the format was unique to Oxford and not used anywhere else in quite the same way.
What changed: Oxford has switched to the TMUA
In January 2026, Oxford announced that the MAT is discontinued and that, from the October 2026 sitting onward, its applicants will take the TMUA (the Test of Mathematics for University Admission) instead. That covers everyone applying for 2027 entry to Oxford Maths and Computer Science, including the joint courses.
This is more than a rebrand. The MAT was Oxford's bespoke paper; the TMUA is a shared national test run by UAT-UK, a joint venture between the University of Cambridge and Imperial College London, and delivered on screen at Pearson VUE test centres. Cambridge, Imperial, LSE and Warwick already used the TMUA, so Oxford has moved from its own exam onto a test the rest of the sector was already sitting. The practical upshot is that Oxford and Cambridge maths and CS applicants now take the same admissions test, and the field sitting the TMUA this cycle is larger and stronger than ever.
Tip
"Did Oxford replace the MAT?" Yes, completely. There is no MAT route for 2027 entry. If a website, tutor or revision pack is still pointing Oxford applicants at the MAT, it is out of date and you should ignore that part of it.
How the formats differ
The two tests feel different the moment you sit down, because they are built differently. The MAT was a single 2.5-hour written paper that mixed multiple-choice questions with longer written answers where you showed full working and earned method marks along the way. The TMUA is two 75-minute papers, each with 20 questions, every one of them multiple choice, sat entirely on screen with no calculator and no formula booklet.
That difference in format drives almost everything else. On the MAT, a partially correct argument could still bank marks. On the TMUA, only your selected option counts: a small slip that would have cost a mark or two on the MAT costs you the whole question. There is a real skill in working backwards from the answer options or testing them, rather than grinding out a complete solution every time, and that skill barely existed on the MAT.
| Feature | MAT (discontinued after 2025) | TMUA (Oxford from October 2026) |
|---|---|---|
| Provider | Oxford's own test | UAT-UK (Cambridge and Imperial), via Pearson VUE |
| Format | Single 2.5-hour written paper | Two papers, 75 minutes each |
| Question type | Mix of multiple choice and longer written answers | All multiple choice, on screen |
| Number of questions | A handful of long problems | 40 in total (20 per paper) |
| Working | Full working shown, method marks awarded | Only the chosen option is marked |
| Calculator | Not permitted | Not permitted (unchanged) |
| Reasoning and proof | Present but not isolated | An entire paper (Paper 2) devoted to it |
| Scoring | Raw marks out of a fixed total | Scaled 1.0 to 9.0 in 0.1 steps, no negative marking |
How the difficulty and style differ
The headline most former MAT candidates need to hear is that the TMUA is less brutal per question but unforgiving on accuracy and speed. MAT problems were long and could take ten minutes or more each; a single clever idea unlocked a whole question. TMUA questions are shorter and more numerous, which means the pressure shifts from deep, sustained problem-solving to quick, slick, repeatable accuracy. Twenty questions in 75 minutes is under four minutes each, with no calculator.
The content is largely the same A-level-and-a-bit foundation, so the mathematics you built up for the MAT is far from wasted. What changes is how it is applied. The TMUA splits into two papers, and the second one is where MAT students are most exposed:
- 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 than A-level, with the obvious method deliberately made the slow one.
- Paper 2 (Mathematical Reasoning) is the genuine departure. It isolates logic, necessary versus sufficient conditions, counterexamples, and spotting the single invalid step inside an otherwise convincing proof. The MAT touched proof, but it never dedicated a whole paper to formal reasoning the way the TMUA does. This is the area where focused practice pays off fastest.
On scoring, the TMUA reports each paper on a scale from 1.0 to 9.0 in 0.1 steps. The national average sits around 4.5, one mark is awarded per correct answer and zero for a wrong or blank one, and there is no negative marking, so you should answer all 40 questions. An educated guess on a hard item is strictly better than a blank, which was never quite true on the MAT.
Here is a real TMUA Paper 1 question at roughly the level a former MAT candidate should be training toward. Attempt it properly before you reveal the solution, and you will feel the format shift first-hand:
What to do if you find old MAT material
You will still find MAT past papers, MAT solution videos and MAT revision books all over the internet, because two decades of the test left a deep archive. Here is how to treat it.
Old MAT papers are not the right preparation for the TMUA, and you should not be drilling them as if they were practice for the test you will actually sit. The format is wrong: long written answers instead of timed multiple choice, no isolated reasoning paper, and a marking scheme that rewards working you will never show on the TMUA. Spending your limited revision time on full MAT papers is the single biggest trap for a switching Oxford applicant.
That said, the underlying mathematics is not worthless. The pure-maths topics a MAT problem exercised, such as polynomials, logs, sequences, graphs and basic calculus, are exactly the content Paper 1 draws on. So a MAT problem can still be a fine content workout, as long as you are clear that you are practising the maths, not the exam. The moment you want to practise the actual test, switch to genuine TMUA material under TMUA conditions.
How preparation differs in practice
If you are pivoting from the MAT, the order of operations is straightforward.
- Relearn the format first. Do a couple of full official TMUA papers under time, 75 minutes and 20 questions each, no calculator, just to absorb the multiple-choice rhythm and the two-paper structure. The maths will feel familiar; the format will not.
- Pour your energy into Paper 2. This is the biggest single 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 that reward deliberate practice.
- Train 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. This habit is new for a MAT student.
- Use real TMUA past papers. UAT-UK publishes a specimen paper plus the full 2016 to 2023 papers for free, and there is no better source for calibrating to the real style.
The deepest preparation comes from understanding why the right answer is right and why each trap option is tempting, which is exactly what a multiple-choice test punishes you for missing. 400+ practice questions, every official TMUA question plus 100+ original trap-based ones, each with an in-depth worked solution that names the trap and shows the fastest method, is how you turn the MAT-to-TMUA switch into an advantage rather than a setback.
