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 potential computer scientists both to develop a deeper understanding of the mathematical foundations of their subject, and 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.
The first year and part of the second year of the course are spent acquiring a firm grounding in the core topics from both subjects; students are then free to choose options from a wide range of Mathematics and Computer Science subjects. In the second year students take part in a group design practical, many of which are sponsored by industry.
This course gives training in logical thought and expression, and is a good preparation for many careers. About 20% of Mathematics and Computer Science graduates tend to go on to further study. Recent graduates secured positions as software and hardware professionals in research, finance and investment analysis, and include a product controller for an international bank, an actuarial consultant and an accountant.
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. The fourth year of the Mathematics and Computer Science degree provides the opportunity to study advanced topics and undertake a more in-depth research project. Students do not need to choose between the three-year or four-year option when applying; all students apply for a 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).
A typical week
Tutorials are usually 2-4 students with a tutor. Class sizes may vary depending on the options you choose. There would usually be around 8-12 students though classes for some of the more popular papers may be larger. Lectures may be up to 100 students.
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.

Oxford University is committed to recruiting the best and brightest students from all backgrounds. We offer a generous package of financial support to Home/EU students from lower-income households. (UK nationals living in the UK are usually Home students.)
These annual fees are for full-time students who begin this undergraduate course here in 2019.
Annual Course fees
(Channel Islands & Isle of Man)
Living costs for the academic year starting in 2019 are estimated to be between £1,058 and £1,643 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.
A tuition fee loan is available from the UK government to cover course fees in full for Home (UK)/EU students undertaking their first undergraduate degree*, so you don’t need to pay your course fees up front.
In 2019 Oxford is offering one of the most generous bursary packages of any UK university to those on a family income of around £42,875 or less, with additional opportunities available to those from households with incomes of £16,000 or less. This support is available in addition to the government living costs support. See further details.
Islands students are entitled to different support to that of students from the rest of the UK.

What are tutors looking for?
The most important qualities we are looking for are strong mathematical ability, the ability to think and work independently, the capacity to absorb and use new ideas, and a great deal of enthusiasm. We use this set of criteria and the result of the Mathematics Admissions Test to decide whom to shortlist for interview.
At the interview we will explore how you tackle unfamiliar problems and new ideas. We are more interested in how you approach problem-solving than whether you can get straight to a solution.
We do not require any previous formal qualification in computing, but we do expect you to demonstrate a real interest in the subject.
For more detail on the selection criteria for this course, please see the Maths Department website.

'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.
My advice to prospective students would be: if you like both Mathematics and Computer Science and think you’ll enjoy the course, give it a shot and apply.'
The Key Information Sets provide a lot of numbers about the Oxford experience – but there is so much about what you get here that numbers can’t convey. It’s not just the quantity of the Oxford education that you need to consider, there is also the quality – let us tell you more.
Oxford’s tutorial system
Regular tutorials, which are the responsibility of the colleges, are the focal point of teaching and learning at Oxford. The tutorial system is one of the most distinctive features of an Oxford education: it ensures that students work closely with tutors throughout their undergraduate careers, and offers a learning experience which is second to none.
A typical tutorial is a one-hour meeting between a tutor and one, two, or three students to discuss reading and written work that the students have prepared in advance. It gives students the chance to interact directly with tutors, to engage with them in debate, to exchange ideas and argue, to ask questions, and of course to learn through the discussion of the prepared work. Many tutors are world-leaders in their fields of research, and Oxford undergraduates frequently learn of new discoveries before they are published.
Each student also receives teaching in a variety of other ways, depending on the course. This will include lectures and classes, and may include laboratory work and fieldwork. But the tutorial is the place where all the elements of the course come together and make sense. Meeting regularly with the same tutor – often weekly throughout the term – ensures a high level of individual attention and enables the process of learning and teaching to take place in the context of a student’s individual needs.
The tutorial system also offers the sustained commitment of one or more senior academics – as college tutors – to each student’s progress. It helps students to grow in confidence, to develop their skills in analysis and persuasive argument, and to flourish as independent learners and thinkers.
The benefits of the college system
- Every Oxford student is a member of a college. The college system is at the heart of the Oxford experience, giving students the benefits of belonging to both a large and internationally renowned university and a much smaller, interdisciplinary, college community.
- Each college brings together academics, undergraduate and postgraduate students, and college staff. The college gives its members the chance to be part of a close and friendly community made up of both leading academics and students from different subjects, year groups, cultures and countries. The relatively small size of each college means that it is easy to make friends and contribute to college life. There is a sense of belonging, which can be harder to achieve in a larger setting, and a supportive environment for study and all sorts of other activities.
- Colleges organise tutorial teaching for their undergraduates, and one or more college tutors will oversee and guide each student’s progress throughout his or her career at Oxford. The college system fosters a sense of community between tutors and students, and among students themselves, allowing for close and supportive personal attention to each student’s academic development.
It is the norm that undergraduates live in college accommodation in their first year, and in many cases they will continue to be accommodated by their college for the majority or the entire duration of their course. Colleges invest heavily in providing an extensive range of services for their students, and as well as accommodation colleges provide food, library and IT resources, sports facilities and clubs, drama and music, social spaces and societies, access to travel or project grants, and extensive welfare support. For students the college often becomes the hub of their social, sporting and cultural life.
