About the course
Computer science is about understanding computer systems and networks 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, and this leads to some fundamental questions:
- How can we capture in a precise way what we want a computer system to do?
- Can we mathematically prove that a computer system does what we want it to?
- How can computers help us to model and investigate complex systems like the Earth’s climate, financial systems or our own bodies?
- What are the limits to computing? Will quantum computers extend those limits?
The theories that are now emerging to answer these kinds of questions can be immediately applied to design new computers, programs, networks and systems that are transforming science, business, culture and all other aspects of life.
The course concentrates on creating links between theory and practice. It covers a wide variety of software and hardware technologies and their applications.
We are looking for students with strong mathematical ability. You will develop these skills to reason rigorously about the behaviours of programs and computer systems.
You will also gain practical problem-solving and program design skills; the majority of subjects within the course are linked with practical work in our well-equipped laboratory.
 | 'I love many things about my course. I love the fact that it’s hard, that it’s very theoretical and that we get a lot of practical work. Even when the work is a little challenging you’re never lost because there are so many people around to help you. The tutors really support you at every step and this motivates you to do well. There are so many wonderful things that I’ve learnt that I never knew existed before. There are definitely moments when, sitting in front of a problem sheet, you realise that you’re at the right place. Computer Science is everything I had hoped for.' Kamil |

Computer Science
A typical week
During the first part of the course, your work will be divided between about ten lectures and two tutorials each week, in addition to about two practical sessions.
In tutorials you will discuss ideas in depth with an experienced computer scientist, usually with just one or two other students.
You will be expected to spend a considerable amount of time developing your own understanding of the topics covered in lectures, answering questions designed to check your understanding, and preparing for tutorials.
As the course progresses, you will also begin to work in small classes of up to ten people on more specialised topics. 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.
In the second year you will take part in a group design practical, which may be sponsored by industry.
In Years 3 and 4 about a third of your time is spent working on your chosen individual project.
Most tutorials, classes, and lectures are delivered by experts in their field, who have years of experience in teaching and research. Some teaching may also be delivered by postdoctoral researchers or postgraduate students who are studying at doctoral level.

Course structure
Computer Science can be studied for three years (BA) or four years, leading to an award of Master of Computer Science (MCompSci).
The fourth year allows the study of advanced topics and an in-depth research project. Students do not need to choose between the three-year and four-year options when applying to the course. 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.

Careers
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
Please note that for full-time Home undergraduate students, current university policy is to charge fees at the level of the cap set by the government. The cap is currently set at £9,250 in 2024/25 and this has been included below as the guide annual course fee for courses starting in 2025. However, this page will be updated once the government has confirmed course fee information for full-time Home undergraduates starting courses in 2025. For details of annual increases, please see our guidance on likely increases to fees and charges.
Fee status | Annual Course fees |
| Home | £9,250 |
| Overseas | £59,260 |
Further details about fee status eligibility can be found on the fee status webpage.
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. |
Islands | Islands students are entitled to different support to that of students from the rest of the UK. Please refer the links below for information on the support to you available from your funding agency: |
Overseas | Please refer to the "Other Scholarships" section of our Oxford Bursaries and Scholarships page. |

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 be doing the same course as you. 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.
