Computer Science Admissions SupportInterviews, the TMUA and choosing a course
One-to-one help for students applying to Computer Science at Cambridge or Oxford, or to Oxford's joint courses with Maths and with Philosophy. Our tutors are Oxford and Cambridge students and graduates.

Four courses, one main test
Every course here uses the TMUA, and two Cambridge colleges add a test of their own. This is how it works for students who applied in October 2026, for entry in 2027.

How we help
Support for every part of the application
Interview practice
Computer science interviews almost always involve maths. A tutor gives you an unfamiliar problem to work through out loud, with hints when you're stuck, just like the real thing.
The TMUA
For next year's applicants. See our TMUA page for how the test works and our TMUA tutors.
Choosing a course
Computer Science, Maths and Computer Science, or Computer Science and Philosophy? A tutor can talk you through how they differ.

Arjan
Hi, I'm Arjan — a First-Class Computer Science graduate from Trinity Hall, Cambridge. Before Cambridge I earned 12 grade 9s at GCSE and 4 A*s at A-Level, including one of the top 50 Computer Science marks in the country. I specialise in Oxbridge Computer Science applications: TMUA preparation, personal statement guidance and mock interviews. Having been through it recently myself, I know what admissions tutors look for — and how overwhelming it can feel from the other side.

My style is patient and question-led: rather than handing you answers, I help you build the understanding and confidence to reason through problems yourself — exactly how I was taught in Cambridge supervisions. My degree specialism was artificial intelligence, which I love using to stretch students and show them where the subject leads. I also hold the JLPT N1, the highest level of the Japanese-Language Proficiency Test, from six years of self-teaching — an experience that shaped how I break difficult material down. Beyond admissions I tutor Maths, Further Maths, Computer Science and Japanese.

Nicholas
I'm Nicholas, a recent graduate Cambridge University studying Computer Science. I sat the TMUA myself as part of my application, so I know what the papers ask of you and how to prepare for them. I've been tutoring for four years at GCSE and A-Level, with A*s of my own in Maths, Further Maths and Computer Science.

The TMUA rewards applying A-level maths in unfamiliar situations and reasoning carefully with logic and proof, rather than recalling method — and that's what I focus on in sessions. Alongside TMUA preparation I tutor Maths, Further Maths and Computer Science at GCSE and A-Level, and I'm happy to talk through what Computer Science at Cambridge is actually like from someone currently doing it.

Questions
Computer Science admissions FAQs
What is the CSAT?
The Computer Science Aptitude Test. At Cambridge, Peterhouse and Trinity require it as well as the TMUA. At Peterhouse, you sit it if you're invited to interview.
Do I need A-level Further Maths?
Cambridge asks you to take it if your school offers it. Oxford highly recommends it, and expects it if your school offers it.
Is there written work?
No. None of these courses asks for written work.
What happens in a computer science interview?
You work through a problem out loud, usually a maths or logic problem you haven't seen before. Tutors give hints if you get stuck, and they care more about your approach than the final answer. Taking time to think is fine.
How many mock interviews should I book?
We suggest a series of sessions with one tutor, as many as you need, to build your technique. A tutor who knows you can see what you're improving on and take each session further than the last.
Then book one or two sessions with tutors you haven't met. On the day, you'll be interviewed by people you've never spoken to, who ask questions in their own way. Practising with someone new shows you whether your technique holds up when the style and the questions are unfamiliar.
Ready to strengthen your Computer Science application?
Tell us a little about the course and where you'd like support — interview, the TMUA or choosing a course — and we'll get back to you about a tutor who fits. No packages, no obligation.
