Artificial intelligence (AI), logic, robotics, modelling and understanding complex physical and social phenomena: these are fascinating areas where computer science and philosophy meet. The two disciplines share a broad focus on the representation of information and rational inference, embracing common interests in algorithms, cognition, intelligence, language, models, proof and verification. Computer scientists need to be able to reflect critically and philosophically as they push forward into novel domains, while philosophers need to understand a world increasingly shaped by technology in which a whole new range of enquiry has opened up, from the philosophy and ethics of AI to the place of computers and robots within society.

Some of the greatest thinkers of the past – including Aristotle, Hobbes, Leibniz and Turing – dreamed of automating reasoning and what this might achieve; the computer has now made it a reality, providing a wonderful tool for extending our speculation and understanding.

The study of philosophy develops analytical, critical and logical rigour, and the ability to understand points of view and to think through the consequences of novel ideas. It stretches the mind by considering a wide range of thought on subjects as fundamental as the limits of knowledge, the nature of reality and our place in it, and the basis of morality. Computer science is about understanding computer systems at a deep level. Computers and the programs they run are among the most complex products ever created. Designing and using them effectively presents immense challenges. Facing these challenges is the aim of computer science as a practical discipline.

Both subjects are intellectually exciting and creative. The degree combines analytical and technical knowledge with discursive, writing and research skills, and the chance to study within two internationally acclaimed academic departments.

Computer Science and Philosophy can be studied for three years (BA) or four years (Master of Computer Science and Philosophy). Students do not need to choose between the three-year and four-year options when applying. Instead all students apply for the four-year course, and then decide at the start of the third year whether they wish to continue to the fourth year (which is subject to achieving a 2:1 at the end of the third year).

The first year covers core material in both subjects, including a bridging course studying Turing’s pioneering work on computability and artificial intelligence. Later years include a very wide range of options, including many courses near the interface between the two subjects. The fourth year enables students to study a variety of advanced topics and complete an in-depth research project.

Computer Science and Philosophy

A typical week

For the first two years, your work is divided between about ten lectures and two to three college-based tutorials each week, alongside Computer Science practical classes – usually one session a week. In the second year you will take part in a Computer Science group design practical, which may be sponsored by industry. In your third and fourth years, Philosophy continues to be taught through tutorials, while there are classes in the department for most Computer Science courses.

Most tutorials, classes, and lectures are delivered by staff who are tutors in their subject. Many are world-leading experts with years of experience in teaching and research. Some teaching may also be delivered by postdoctoral researchers or postgraduate students who are studying at doctorate level.

Or any other equivalent (see other UK qualifications, and international qualifications

Wherever possible, your grades are considered in the context in which they have been achieved.  (See further information on how we use contextual data.) 

Subject requirements

  Essential: Candidates are expected to have Mathematics to A-level (A* or A grade), Advanced Higher (A grade), Higher Level in the IB (score 7) or another equivalent. 

Further Mathematics is highly recommended.* Those taking Further Mathematics A-level or AS-level are expected to achieve at least Grade A.

*If your school offers Further Maths A-Level we expect you to have taken it. However, we understand that not all schools offer Further Maths, and so we do consider applications from people with a single Maths A-level.  If you are based in England, and your school doesn't offer Further Maths please see the Advanced Mathematics Support Programme website as they can provide extra maths support. In Wales, see the Further Mathematics Support Programme Wales.  

Please note from 2018-20, 97% of A-level students who were offered places for Computer Science courses (including joint courses) took Further Maths to A-level.

If a practical component forms part of any of your science A‐levels used to meet your offer, we expect you to pass it.

If English is not your first language you may also need to meet our English language requirements.


All candidates must follow the application procedure as shown in applying to Oxford. The information below gives specific details for students applying for this course. For more information on how to apply, including advice on interviews, specimen MAT papers, and sample questions, please see the Computer Science department website.

Everything you need to know, including guidance on how to prepare, can be found on the MAT page

Written work

You do not need to submit any written work when you apply for this course.

What are tutors looking for?

For Computer Science: strong mathematical aptitude, the ability to think and work independently, the capacity to absorb and use new ideas, and enthusiasm. For Philosophy: a critical and analytical approach to abstract questions, the ability to defend a viewpoint by reasoned argument, and a desire to delve deeper into the way we think about things. You do not need to have previously studied either subject.

For more detail on the selection criteria for this course, please see the Computer Science and Philosophy websites.


Graduates will have highly marketable skills. Computer Science teaches you how to program, to design processes that are effective and efficient, to reason logically and formally. Philosophy teaches you how to analyse complex concepts and the interconnections between them and – crucially – how to express such analysis, elegantly and precisely, in written form. This ability to analyse complex issues, both technically and discursively, provides the intellectual equipment needed for technical leadership and high-level positions in today’s world.

We don't want anyone who has the academic ability to get a place to study here to be held back by their financial circumstances. To meet that aim, Oxford offers one of the most generous financial support packages available for UK/Republic of Ireland students and this may be supplemented by support from your college.

Further information for EU students starting in 2022 is available here.


These annual fees are for full-time students who begin this undergraduate course here in 2022.

Living costs

Living costs at Oxford might be less than you’d expect, as our world-class resources and college provision can help keep costs down.

Living costs for the academic year starting in 2022 are estimated to be between £1,215 and £1,755 for each month you are in Oxford. Our academic year is made up of three eight-week terms, so you would not usually need to be in Oxford for much more than six months of the year but may wish to budget over a nine-month period to ensure you also have sufficient funds during the holidays to meet essential costs. For further details please visit our living costs webpage.

Financial support


A tuition fee loan is available from the UK government to cover course fees in full for Home (UK, Irish nationals and other eligible students with UK citizens' rights - see below*) students undertaking their first undergraduate degree**, so you don’t need to pay your course fees up front.

In 2022 Oxford is offering one of the most generous bursary packages of any UK university to Home students with a family income of around £42,875 or less, with additional opportunities available to UK students from households with incomes of £27,500 or less. The UK government also provides living costs support to Home students from the UK and those with settled status who meet the residence requirements.

*For courses starting on or after 1 August 2021, the UK government has confirmed that EU, other EEA, and Swiss Nationals will be eligible for student finance from the UK government if they have UK citizens’ rights (i.e. if they have pre-settled or settled status, or if they are an Irish citizen covered by the Common Travel Area arrangement). The support you can access from the government will depend on your residency status.

Contextual information

Course data from Discover Uni provides applicants with statistics about undergraduate life at Oxford. But there is so much more to an Oxford degree that the numbers can’t convey.

The Oxford tutorial

College tutorials are central to teaching at Oxford. Typically, they take place in your college and are led by your academic tutor(s) who teach as well as do their own research. Students will also receive teaching in a variety of other ways, depending on the course. This will include lectures and classes, and may include laboratory work and fieldwork. However, tutorials offer a level of personalised attention from academic experts unavailable at most universities.

During tutorials (normally lasting an hour), college subject tutors will give you and one or two tutorial partners feedback on prepared work and cover a topic in depth. The other student(s) in your college tutorials will be from your year group, doing the same course as you and will normally be at your college. Such regular and rigorous academic discussion develops and facilitates learning in a way that isn’t possible through lectures alone. Tutorials also allow for close progress monitoring so tutors can quickly provide additional support if necessary.

College life

Our colleges are at the heart of Oxford’s reputation as one of the best universities in the world.

  • At Oxford, everyone is a member of a college as well as their subject department(s) and the University. Students therefore have both the benefits of belonging to a large, renowned institution and to a small and friendly academic community. Each college or hall is made up of academic and support staff, and students. Colleges provide a safe, supportive environment leaving you free to focus on your studies, enjoy time with friends and make the most of the huge variety of opportunities.
  • Each college has a unique character, but generally their facilities are similar. Each one, large or small, will have the following essential facilities:
    • Porters’ lodge (a staffed entrance and reception)
    • Dining hall
    • Lending library (often open 24/7 in term time)
    • Student accommodation
    • Tutors’ teaching rooms
    • Chapel and/or music rooms
    • Laundry
    • Green spaces
    • Common room (known as the JCR).
  • All first year students are offered college accommodation either on the main site of their college or in a nearby college annexe. This means that your neighbours will also be ‘freshers’ and new to life at Oxford. This accommodation is guaranteed, so you don’t need to worry about finding somewhere to live after accepting a place here, all of this is organised for you before you arrive.
  • All colleges offer at least one further year of accommodation and some offer it for the entire duration of your degree. You may choose to take up the option to live in your college for the whole of your time at Oxford, or you might decide to arrange your own accommodation after your first year – perhaps because you want to live with friends from other colleges.
  • While college academic tutors primarily support your academic development, you can also ask their advice on other things. Lots of other college staff including welfare officers help students settle in and are available to offer guidance on practical or health matters. Current students also actively support students in earlier years, sometimes as part of a college ‘family’ or as peer supporters trained by the University’s Counselling Service.
