Oxford is Replacing the MAT with TMUA — What Maths and CS Applicants Need to Know for 2027 Entry

Summary: Oxford has permanently retired the MAT. From October 2026 (for 2027 entry (2026 admissions cycle)), all Oxford applicants for Maths, Computer Science, and joint honours courses must sit the TMUA instead. The core subject content is similar, but TMUA is entirely multiple-choice, includes a formal logic and proof paper that the MAT never had, and scores you against every other TMUA candidate in the country — not just Oxford applicants. MAT past papers are still useful for Paper 1 preparation. Paper 2 requires completely separate work.

The MAT Is Gone. Here Is What Has Replaced It.

Oxford has permanently replaced the MAT with TMUA for all Maths and Computer Science applicants, effective from the October 2026 sitting. Every Oxford applicant for Mathematics, Mathematics and Statistics, Mathematics and Computer Science, Mathematics and Philosophy, Computer Science, and Computer Science and Philosophy now sits TMUA instead of MAT. The MAT final sitting was October 2025 and it will not return. TMUA Paper 1 covers similar content to the MAT. TMUA Paper 2 — formal logic and proof — has no MAT equivalent and is the section most likely to catch applicants who try to transfer MAT preparation directly.

From the 2026 testing cycle — that is, October 2026 for students applying to start in autumn 2027 — Oxford Maths, CS, and joint honours applicants sit the TMUA: the Test of Mathematics for University Admission. This is the same test that Cambridge has required for Economics applicants since 2016 and that Imperial, LSE, UCL, Warwick, and Durham already use for their own Maths and CS courses.

This matters beyond just format. When you sit TMUA for an Oxford application, your score is visible to every university in your UCAS form that uses TMUA. You are no longer competing within an Oxford-specific applicant pool. You are competing against the entire national cohort of TMUA candidates.

Which Oxford Courses Now Require TMUA Instead of MAT

The following Oxford courses previously required the MAT and now require TMUA from 2027 entry (2026 admissions cycle) onwards.

Oxford Course Test from 2027 Test until 2026

Mathematics and StatisticsTMUAMAT
Mathematics and Computer ScienceTMUAMAT

Note

If you are applying to Oxford Economics and Management or PPE, you do not sit TMUA — those courses now require TARA (Test of Academic Reasoning for Admissions), which replaced the TSA.

How TMUA Differs from MAT — The Changes That Actually Matter for Preparation

These two tests cover similar mathematical content, but they are not the same test. The differences will affect how you spend your preparation time.

What Paper 1 looks like

TMUA Paper 1 tests mathematical knowledge and its application. Topics are drawn from A-level Maths and some AS Further Maths content — calculus, algebra, coordinate geometry, sequences, trigonometry, exponentials and logarithms. The question style rewards precision and speed: 20 questions in 75 minutes, all multiple-choice, no written working required. This is the paper that feels closest to the MAT Section 1 multiple-choice questions. If you have been working through MAT past papers, this content is still directly useful.

What Paper 2 looks like — and why it is the harder adjustment

TMUA Paper 2 tests mathematical reasoning, logic, and proof. This has no equivalent in the MAT. The full content is specified in the UAT-UK Notes on Logic and Proof document, which covers conditional statements, contrapositives, necessary and sufficient conditions, direct proof, proof by contradiction, proof by induction, disproof by counterexample, and identifying errors in mathematical arguments.

Paper 2 is where most former MAT-preparers underperform. Students who have spent months on MAT practice papers arrive at Paper 2 with strong calculus and algebra skills but no experience with formalised proof structures. The questions do not require advanced mathematical content — they require precise logical reasoning, which is a different skill and needs to be trained separately.

What You Can Still Use from Your MAT Preparation

If you or your child has been preparing with MAT resources, not all of that work is wasted. Here is an honest assessment of what transfers.

MAT Resource Useful for TMUA? Which part
MAT Section 1 MCQ (all years)Yes — directlyPaper 1 practice
MAT long questions (2010–2025)PartiallyMathematical fluency, not format
MAT syllabus topicsYes — identical coverageBoth papers (content)
MAT mark schemesLimitedMAT awards method marks; TMUA does not
Logic and proof preparationNot covered by MATMust use UAT-UK Notes on Logic and Proof
The most important thing MAT preparation does not cover

Paper 2 is entirely logic and proof. The UAT-UK Notes on Logic and Proof document is the official specification — download it from the UAT-UK website and treat it as a syllabus. Every concept in it has appeared in TMUA Paper 2. None of it appears in the MAT.

What a Competitive TMUA Score Looks Like for Oxford

TMUA scores run on a 1.0 to 9.0 scale. Scores are reported separately for Paper 1 and Paper 2, and as a combined score. Oxford uses the combined score for shortlisting decisions.

Oxford does not publish a fixed cut-off. The admissions team uses TMUA scores alongside UCAS predicted grades, school context, and the personal statement to decide who to invite for interview. That said, the practical benchmarks are well established from Cambridge and Imperial data, which has accumulated since 2016.

TMUA Score Approximate Percentile Context for Oxford
8.5 – 9.0Top 1%Exceptional. Very strong interview position.
7.5 – 8.5Top 5%Very competitive for Oxford interview.
6.5 – 7.5Top 10–20%Competitive. Strong applications will progress.
5.5 – 6.5Top 30–40%Possible, but Oxford shortlisting less likely without an exceptional profile.
Below 5.5Below 40th percentileUnlikely to reach Oxford interview shortlist.

One important shift with the MAT-to-TMUA change: the MAT pool was exclusively Oxford applicants, a self-selected, highly competitive group. The TMUA pool includes every student applying to any university that uses TMUA — a larger and more varied group. This means a score of 6.5 in the TMUA national pool may represent stronger relative performance than a comparable raw score in the old Oxford-only MAT pool.

One Test, Multiple Universities — What This Changes Strategically

Under the old system, a student applying to Oxford Maths (MAT), Imperial Maths (MAT or TMUA), and Cambridge Maths (STEP) was doing three different tests. From 2026, if you are applying to Oxford Maths, Imperial Maths, UCL Maths, Warwick Maths, and Cambridge Economics, every single one of those applications can be covered by one TMUA sitting in October.

This is genuinely useful. One test, one registration, one preparation track, one October morning. All universities in your UCAS application that require TMUA receive the same score automatically.

The one exception for Maths applicants: Cambridge Maths still requires STEP (Sixth Term Examination Paper) in addition to TMUA. STEP is a separate, harder written exam taken in summer after A-levels. If you are applying to Cambridge Maths, you need both. If you are only applying to Oxford, you need only TMUA.

How to Prepare — The Honest Version

The available preparation materials for TMUA are limited compared to what the MAT had after 18 years of past papers. UAT-UK does not release papers from recent sittings. The officially available materials are: the content specification, the Notes on Logic and Proof document, and a small number of specimen papers. TMUA papers from 2019 to 2023 are available for Paper 1 content practice.

Paper 1 preparation

Work through all available TMUA past papers from 2019 onwards. Supplement with MAT Section 1 questions from 2010 to 2025 — there are hundreds of these and they test equivalent content. Time yourself strictly: 20 questions in 75 minutes is 3.75 minutes per question. Without a calculator. Speed and accuracy under time pressure is the skill being tested.

Paper 2 preparation

Download the UAT-UK Notes on Logic and Proof. Read it carefully. Every concept in it — conditional statements, contrapositives, necessary vs sufficient, direct proof, proof by contradiction, proof by induction, counterexamples, identifying errors in proofs — has been tested. Then work through every available TMUA Paper 2 past paper and specimen. There is no MAT equivalent. This paper rewards students who have explicitly trained it; it penalises those who arrive assuming their A-level mathematical ability will carry them through.

The biggest mistake to avoid

Spending all preparation time on Paper 1 and treating Paper 2 as an afterthought. Paper 2 is equally weighted in the final score. A strong Paper 1 combined with a weak Paper 2 will produce an average combined score that does not represent what you are capable of in the maths content. Treat the two papers as two separate disciplines requiring separate preparation tracks.

Summary

Oxford has permanently replaced the MAT with TMUA for all Maths, Computer Science, and joint honours applicants. The change takes effect for the October 2026 sitting, applying to students entering Oxford in autumn 2027. TMUA Paper 1 covers similar content to the MAT and existing preparation materials remain useful. TMUA Paper 2 is entirely new territory — formal logic and proof — and requires dedicated preparation from the UAT-UK Notes on Logic and Proof document. Registration for the October sitting opens around August 2026 and fills quickly. Oxford applicants must sit October only. Preparation should begin well before registration opens.
