TMUA vs MAT: what changed at Oxford

Oxford retired the Maths Admissions Test after the October 2025 sitting. Everyone applying for 2027 entry sits the TMUA instead, and the MAT will not run again.

What actually changed

The last MAT was sat in October 2025, by people applying for 2026 entry. Anyone applying in autumn 2026 to start in 2027 sits the TMUA, across every Oxford mathematics and computer science course. Most of the confusion about this comes down to which year is being named, because pages written for an earlier cycle still describe the MAT as Oxford's test and were never updated.

The change is larger than swapping one paper for another. The MAT was Oxford's own test, set and marked in Oxford, and its two long questions were read by an examiner who could give credit for a partial argument. The TMUA is a national test that several universities share, and none of your working is seen: each paper is twenty multiple-choice questions, and only the option you select counts.

The total time is almost identical, but it is split across two papers of seventy-five minutes, which leaves a little under four minutes a question where the MAT gave you five and a half. The pace, rather than the syllabus, is what most people notice first.

The MAT and the TMUA, side by side

What MAT preparation is still worth doing

Most of what you did for the MAT still counts. The two syllabuses are close, since both stop at roughly the first year of A level Maths and neither expects Further Maths, so the algebra, the graph sketching, the polynomial and logarithm work and the counting arguments all carry over. The multiple-choice section of a MAT paper is close to ideal TMUA practice, being the same content in the same format, and old MAT papers are worth working through for that section alone.

What does not carry over is the long questions and the habits they encouraged. On the MAT it was rational to spend fifteen minutes building a careful written argument, because the argument was what earned the marks. On the TMUA that time does not exist and the argument is never read, so a question you cannot see a route through within a few minutes is one to leave and come back to.

The larger gap is Paper 2. The MAT tested reasoning implicitly, through the shape of its long questions, whereas the TMUA gives it a paper of its own: necessary and sufficient conditions, what a single counterexample settles, and where a printed argument breaks down. Almost nobody meets this explicitly at school and nothing in MAT preparation covers it directly, so it is usually where the remaining work is.

Where to start now

The two things worth settling early are what the TMUA asks of you and when you have to sit it. What the TMUA looks like covers the format question by question, and the key dates cover registration, which closes well before the test and is the deadline people actually miss. The Oxford page sets out the requirement course by course.

Past MAT papers are on this site alongside the TMUA ones, so you can keep using the material you had already started on and sit it to the TMUA clock instead.

TMUA and MAT: frequently asked questions

Does Oxford still use the MAT?

No. The last MAT was sat in October 2025, for 2026 entry, and it will not run again. Oxford uses the TMUA from 2027 entry onwards for all of its mathematics and computer science courses.

Is the TMUA harder than the MAT?

Neither syllabus goes deeper than the other, so they are hard in different ways rather than one being harder. The MAT gave you more time per question and marks for partial working, which suited candidates who reason carefully and slowly. The TMUA gives you neither, so it rewards speed and confidence in an answer you cannot show working for.

Are MAT past papers still useful?

Yes, particularly the multiple-choice section, which is the same syllabus in the same format as the TMUA. The long questions are still good mathematics and good interview practice, but they train you to work at a pace the TMUA does not allow, so treat them as maths rather than as timed preparation.

Why did Oxford drop the MAT?

Oxford moved its admissions testing onto the shared UAT-UK system run with Pearson VUE, which also absorbed the Physics Aptitude Test and the Thinking Skills Assessment. For candidates the practical effect is one fewer Oxford-specific test to prepare for, since the TMUA is already required at several other universities.

Which Oxford courses need the TMUA?

Mathematics, Mathematics and Statistics, Mathematics and Philosophy, Mathematics and Computer Science, Computer Science, Computer Science and Philosophy. All of them used the MAT until 2026 entry.

When do Oxford applicants sit the TMUA?

In the October window, which for 2027 entry runs from 12 to 16 October 2026. Oxford applicants sit in October rather than January, since a January score would arrive after decisions have been made.

Oxford publishes the current requirement on its own admissions test page.
