Practise your Oxford or Cambridge interview
Toby is an AI interviewer that runs practice interviews by voice. Choose your university and course, and Toby interviews you the way Oxford and Cambridge tutors do: an unfamiliar problem, time to think, a hint when you're stuck, and questions that push on your reasoning. Ready-made interviews cover 10 Oxford and Cambridge courses, each built from the university's own guidance. Your first 5 minutes are free.
Ready-made Oxford and Cambridge interviews
Each interview follows the real format for 2027 entry, with problems at the course's level, scored on what its tutors look for.
University of Oxford
- Physics: three online interviews of 20 to 30 minutes, two at your first college and one at a second
- Mathematics: two or three online interviews of about 25 minutes
- Mathematics and Statistics: the same maths interviews as Mathematics
- Mathematics and Computer Science: separate maths and computer science interviews
- Computer Science: usually three online interviews of about 30 minutes, with no programming needed
- Engineering Science: two online interviews at two colleges, about 30 minutes each
University of Cambridge
- Mathematics: usually two interviews of 25 to 30 minutes, often one pure and one applied
- Computer Science: usually two interviews, one on computer science and one on maths, with no programming needed
- Engineering: usually two interviews, often one on problems and one more of a discussion
- Natural Sciences: physical sciences, usually one maths-led interview and one on physics or chemistry

How it works
- Choose your university and course.
Add your personal statement if you'd like Toby to ask about it, and notes on anything you want to practise.
- Prepare.
Your prep page sets out the interview format, what tutors look for and practice problems with hints and worked solutions.
- Take the interview.
Choose 10, 20 or 30 minutes. Toby puts each problem on screen and talks it through with you by voice.
- Read your debrief.
You get a mark out of 10, a score against each criterion, notes on every question and the full transcript.
Like a tutorial, not a quiz
Oxford and Cambridge interviews are conversations about problems you haven't seen before. Toby is built to run them the same way:
- Unfamiliar problems. They're built on school maths and science and taken somewhere new, including questions the universities have published.
- Time to think. Toby gives you a hint only when you're stuck, and the hint nudges you on without giving the answer away.
- Questions that push back. Why does that work? What happens if we change this? Does your answer make sense in the limit?
- No running commentary. Like a real tutor, Toby doesn't tell you after every step whether you're right.
- Your questions at the end. Toby answers questions about the course from the university's published information.
Built from the universities' own guidance
Each interview is researched from the university's admissions pages, the department's interview guidance and questions the university has published. The facts were last checked in October 2026, and every course page lists its sources.
Each course has between 27 and 53 practice problems, written to the universities' style and level, with every result independently re-derived. Where a university publishes how it marks interviews, the debrief uses that scale. Oxford Physics, for example, marks each interview out of 10.

Frequently asked questions
Is Toby a real person?
No. Toby is an AI interviewer that runs practice interviews by voice. For university admissions, he's built to behave like an Oxford or Cambridge tutor: he sets a problem, gives you time to think, offers a hint when you're stuck and asks you to explain your reasoning.
Which university interviews does Toby cover?
Toby has ready-made interviews for 10 courses. At Oxford they are Physics, Mathematics, Mathematics and Statistics, Mathematics and Computer Science, Computer Science and Engineering Science. At Cambridge they are Mathematics, Computer Science, Engineering and Natural Sciences (physical sciences). For any other course, you can write your own brief and Toby builds an interview from it.
Will Toby ask me the same questions as the real interview?
No. Oxford and Cambridge tutors set their own questions, so yours will differ. Toby uses problems in the style and at the level of the real interviews, including some the universities have published.
How long is a Toby practice interview?
A Toby practice interview lasts 10, 20 or 30 minutes, whichever you choose. Real Oxford and Cambridge interviews usually last 20 to 30 minutes each.
Is Toby free?
Your first 5 minutes with Toby are free. After that, interviews cost 50p a minute, in packs from £5, and bought minutes last 6 months. To read your debriefs, you add a card to your account, and adding one doesn't charge anything.
Can Toby ask about my personal statement?
Yes. Add your personal statement when you choose your course, and Toby can ask about it during the interview, as tutors sometimes do.
How does Toby mark a practice interview?
Toby marks each practice interview out of 10 against the criteria for the course. Where a university publishes its own scale, as Oxford Physics does, Toby uses it. Otherwise, 6 is acceptable, 7 good and 8 strong. A practice mark is a guide, not a prediction.
Toby is independent and isn't affiliated with or endorsed by the University of Oxford or the University of Cambridge.
