About the course

This joint degree offers the opportunity to combine an appreciation of mathematical reasoning with an understanding of computing.

Mathematics is a fundamental intellectual tool in computing, but computing is increasingly used as a key component in mathematical problem-solving.

The course concentrates on areas where mathematics and computing are most relevant to each other, emphasising the bridges between theory and practice.

It offers opportunities for students to develop a deeper understanding of the mathematical foundations of their subject. The course helps students to acquire a familiarity with the mathematics of application areas where computers can solve otherwise intractable problems. It also gives mathematicians access to both a practical understanding of the use of computers and a deeper understanding of the limits on the use of computers in their own subject.

'For me the best bit of the course is the practical element, such as imperative programming. I like to see new techniques for algorithms and structures because I find it exciting to see how they could be used in the real world. I find the tutorial system very helpful – I think it is the best thing about Oxford. The people here are very competent and the facilities are well suited to the course.'

Structure

A typical week

The typical weekly timetable for a student in Mathematics and Computer Science is similar to that for Computer Science or Mathematics.

Tutorials are usually 2-4 students with a tutor. Class sizes may vary depending on the options you choose. There would usually be around 8-15 students though classes for some of the more popular papers may be larger. Lectures may be up to 120 students.

As the course progresses there will be opportunity to undertake project work. There will be a group project in year two and, for those that choose to continue to year four, a large individual project or dissertation.

Throughout your time studying you will learn from leading maths and computer science specialists and researchers.

To find out more about how our teaching year is structured, visit our Academic Year page.

Course structure

Mathematics and Computer Science can be studied for three years, leading to the award of a BA degree, or for four years, leading to the award of Master of Mathematics and Computer Science (MMathCompSci).

Students do not need to choose between the three-year and four-year options when applying. All students apply for the four-year course, and then decide by the end of their third year whether they wish to continue to the fourth year. In order to proceed into the fourth year (part C), students will need to achieve a 2:1 or higher classification at the end of their third year.

Note: These annual fees are for full-time students who begin this undergraduate course here in 2025. Course fee information for courses starting in 2026 will be updated in September.

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 students and this may be supplemented by support from your college.

Fees

For more information please refer to our course fees page. Fees will usually increase annually. For details, please see our guidance on likely increases to fees and charges.

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 2025 are estimated to be between £1,425 and £2,035 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

Home

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 2025 Oxford is offering one of the most generous bursary packages of any UK university to Home students with a family income of around £50,000 or less, with additional opportunities available to UK students from households with incomes of £32,500 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.

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 tutorials will typically be doing the same course as you and covering the same topic. 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.
