The Oxford Maths interview

Oxford Maths interviews take place online in December. You'll usually have one or two interviews at your first-choice college and at least one at another, each about 25 minutes and largely mathematical: tutors give you a problem or a definition and watch how you work through it out loud.

For the 2026 admissions round (2027 entry), shortlisting uses the TMUA, which replaced Oxford's own MAT. In the 2023-25 cycles about 32% of applicants were interviewed and 9% were successful. Here is the format, a question Oxford has published, what a strong answer does and how to prepare.

How does the Oxford Maths interview work?

The Mathematical Institute puts it simply: "We are trying to see how you think when you do Mathematics." It also says tutors "are not mind-readers", so if you don't say anything, they can't tell what you're thinking.

A question Oxford has published

Oxford's sample interview questions page includes this one from a Mathematics tutor: "Imagine a ladder leaning against a vertical wall with its feet on the ground. The middle rung of the ladder has been painted a different colour on the side, so that we can see it when we look at the ladder from the side on. What shape does that middle rung trace out as the ladder falls to the floor?" The tutor explains that it tests whether you can do what mathematicians do: strip away the unimportant information and use maths to represent what's going on. (Source: University of Oxford, sample interview questions.)

• What a strong answer does: draws it first. It puts the wall and floor on axes, names the ladder's length, and writes down where the top and foot are.
• The key move: finds the middle rung's coordinates and asks what stays the same as the ladder slides. Then it checks the guess at the start and end positions.
• Weak answer: sketching a few positions and guessing from the drawing, with no set-up and no check. The tutor notes a sketch is a fine start, but you can't be sure it's accurate.
• What usually comes next: the tutor's own suggested extension is a point a third or two-thirds of the way up the ladder, to see whether your method generalises.

What kinds of questions come up

What about Cambridge Maths?

Cambridge Mathematics also requires the TMUA, and offers usually include grades in STEP papers, which you sit after you're made an offer. Cambridge reported 8 applications per place and 258 students accepted in the 2025 cycle. Interviews follow the usual Cambridge pattern of one or two in December, with problem-solving and shared working. See what to expect at a Cambridge interview.

How to prepare for an Oxford Maths interview

1. Do lots of problems on and near your syllabus. That's the Mathematical Institute's own advice, and it says you don't need special training.
2. Talk while you work. Practise TMUA or old MAT questions out loud, as the department suggests, ideally in front of a teacher.
3. Practise sketching. Curve sketching comes up often. Be able to sketch quickly and explain each feature.
4. Start every problem the same way. Draw it, try a small case, name your variables. A good start buys you time to think.
5. Learn to take a hint. The tutor's nudge is part of the interview. Practise picking it up instead of restarting.
