Why study Computer Science at Christ's College?

Christ's is a few minutes' walk of Mill Lane where first-year lectures for Computer Science are held. The College also provides a modern library, a theatre, sporting facilities, playing fields, social activities and clubs and societies open to all.
 

Course structure and content

The Computer Science course (or ‘tripos’) is a four-year degree, and you can choose from a range of options in the first year.

Please visit the University website for full details of the Computer Science course content and structure, including the course film. You will also find information on the Department of Computer Science and Technology page for prospective applicants. If you have any further questions, please contact undergraduate.admissions@cst.cam.ac.uk. 
 

Teaching

Christ’s’ Fellows possess a range of expertise that covers the full spectrum of the Computer Science course, so you can expect strong, informed teaching.

• Professor Richard Mortier: Christ’s Director of Studies in Computer Science and University Lecturer in the Systems Research Group at the Cambridge University Computer Lab
• Professor Marcelo Fiore: Professor in Computer Science and a member of the Programming, Logic and Semantics Group
• Professor Ian Leslie: Professor of Computer Science and a member of the Systems Research Group
• Professor Steven Murdoch: Professor of Security Engineering at UCL and bye-fellow at Christ's College.
• Dr Damon Wischik: University Lecturer in the Human-Centred Computing Group at the Cambridge University Computer Lab.

Christ’s College Director of Studies in Computer Science Prof Richard Mortier can advise you on choosing options and arrange your twice-weekly ‘supervisions’. These small-group teaching tutorials offer support and tuition tailored to your personal work. As other universities usually tutor in much larger groups, this approach is a real advantage of a Cambridge education.

Our students enjoy the fact that Christ's College is just a few minutes’ walk from Mill Lane, home of first-year Computer Science lectures.

How to Apply

Visit How to Apply for full details and a timeline of the application process. We welcome applicants from all backgrounds and school types, all over the world. If you're applying from outside the UK, please read our international students section.

Subject requirements

We particularly welcome applications from candidates with a strong background in mathematics and/or science.

If you are taking UK-designed A-levels (these include International A levels but not Singapore A levels).

• A level Mathematics is required
• A level Further Mathematics is required
• It is desirable to take Physics and/or Computer Science.

If your school does not offer Further Maths, you may be able to get support from the Advanced Mathematics Support Programme. 

For all other qualifications, including the International Baccalaureate and Scottish Advanced Highers: 

• Mathematics (or an equivalent) is essential. IB students must take Maths Analysis and Approaches and students in the USA system should take AP Calculus BC.
• You must also take at least one other subject out of Physics, Chemistry or Biology.
• It is desirable to take Physics and/or Computer Science.

Students in the Scottish system should see the advice here and students taking the International Baccalaureate should see the information here.

A number of our international candidates (from countries where you study a wide range of subjects at school in the final two years) take part in Mathematics competitions as a way to focus on extending mathematical knowledge and ability.
 

TMUA (registration required)

All applicants for Computer Science at Cambridge must sit a computer-based assessment called the Test of Mathematics for University Admissions (TMUA). This is the same at all Cambridge Colleges. 

TMUA 2025 Registration deadline: To be confirmed (deadline expected to be available by early May)
TMUA 2025 Test dates: Monday 13 and Tuesday 14 October 2025 (as confirmed on the UAT UK website)

You must register and take the TMUA in the correct sitting. For students applying to Cambridge in September 2025 (for Oct 26 or deferred Oct 27 entry), please check the dates and details on the TMUA website from May 2025. You can normally create an account, pay the registration fee and register from early August, the registration deadline is normally mid-September (date to be confirmed), and you take the TMUA in person at a Test Centre in mid-October. You must use the October sitting in the year you apply - tests sat on other dates are not accepted. There are test centres in over 180 countries around the world. You will receive your results via Pearson Vue approx six weeks after you sit the test (results are automatically shared with us as well - you do not need to send them to us). 

Please read the TMUA summary then look at the ESAT-TMUA website for full details, including preparation resources, how to register and book your test, details for UK applicants in financial need and students who have access requirements for a disability. 

There is no set score that we are looking for and we don't expect you to get every question right. The TMUA forms part of our holistic admissions process, which means that we will look at your scores in the context of your whole application.

Interviews

If we select you for interviews, these usually take place in early December. At Christ's we do all of our interviews online. You can have your interviews either at home (most applicants do this) or at school (if easier). The interviews last 35-50 minutes in total. At Christ’s, we usually split the time into two interviews with academics in Computer Science.

Further, more general information about interviews (including two useful films) is available in the Cambridge interviews section, and it's worth also having a look at supervisions (short film here), as interviews are similar to what you do every week as a Cambridge student.

Offers

Christ's College does not have fixed quotas of places for different subjects and the exact numbers admitted in any one year will depend upon the strengths of the fields of applicants in various subjects.

We define the terms of each offer individually, but the minimum offer for Computer Science is

• A*, A*, A at A-level
• 42 points overall in the International Baccalaureate with 7, 7, 6 in relevant Higher Level subjects
• A1, A1, A2 in three relevant Scottish Advanced Highers (See the Computer Science from Scotland page)

You need to be academically ambitious: the majority of Christ's students arrive with higher grades than are required.

If you're taking another qualification, we expect you to be working at or close to the top of the mark range, for example

• Baccalauréat français international (BFI): 17 (mention très bien) out of 20 overall, with a minimum of 17 in relevant subjects including Mathematics
• European Baccalaureate: at least 85% overall, with 9/10 in relevant subjects including Mathematics

You can look up other qualifications in the offer levels for other exam systems and international entry requirements, and if you are applying from outside the UK please read the Christ's international students section for further information and check the country pages.

If you will have finished school when you apply, please also read about post-qualification applications, taking a gap year, and, if relevant, applying from a university.

Come to an Open Day / Webinar

Our open days and events page advertises regular online opportunities as well as events you can attend in Cambridge. If you can, sign up for a College Open Day (our October, February and September events normally include a meeting with a subject specialist). Between February and August we run regular webinars:

• Subject Matters: The importance of post-16 subject choices (this one is also run Sept - Nov)
• Cambridge for Beginners
• Personal Statements and preparing for an application

Further subject-specific opportunities you might wish to consider include Subject Masterclasses organised by Cambridge Admissions Office, and subject-specific talks in the July Cambridge Open Days. If you are a UK student from a background where there is little tradition of entry to Higher Education, you can apply to attend a Sutton Trust Summer School in Computer Science or to shadow a current undergraduate studying Computer Science via the Cambridge SU Shadowing Scheme (do be aware that there's a high proportion of applicants to places for both of these last two opportunities so please don't be discouraged if you don't get a place).
