How to apply

Detailed instructions for the applications procedure are contained in the University's Digital Prospectus for Undergraduates . The information given on this webpage is intended to supplement the official information given there. For a general overview of the admissions process at Oxford see the University of Oxford's how to apply video(applicable for any Oxford course).

The following diagram shows the major steps involved in applying for an undergraduate (first) degree course here at the Department of Computer Science. Click on each step to view more information.

Dates below are for the current admissions round, subject to change, with future admissions rounds expected to have similar dates. Any updates to times will be reflected here.

Entry requirements

2. Choose a college

There are over 20 Oxford colleges that accept undergraduates for Computer Science and/or joint degrees.

Does it matter which college I choose?

You need to choose a college that offers the course you would like to apply to or make an open application.

We work very hard to make sure that the best candidates are offered a place, irrespective of which college they apply for. Different people have many different reasons for choosing the college they eventually settle on.

You might want to think about the size or age of a college, the location, the costs of living there, the accommodation and facilities available. Colleges provide a wide variety of accommodation and meal options.

You can have a look at college pages to help you decide.

Open applications

You don't have to choose a college; you can make an open application, in which case you will be allocated to a college that offers your chosen course. The college that receives your application will not know that you made an open application, and you will not be asked about it at the interview. Your application will then be treated exactly as if you had directly applied to that college. There is no admissions advantage or disadvantage to making an open application, and the tutors considering your application won't even be able to tell that you made an open application.

Open days

A tour of the Department of Computer Science is available.

If you are able to, you might want to come and visit Oxford during our open days to have a look around some of the colleges.

If you are not able to visit us in person, you can view some video panoramas in the Chemistry Department's virtual tour of Oxford.

3. Register for the Maths Admissions Test

MAT registration deadline: Thursday 15 August to Friday 4 October 2024

Please note that in early 2024, the University is reviewing arrangements for all tests. The MAT syllabus is not changing. Past questions are still good practice. The MAT format (length of test, number of questions, etc) may change. Please see for updates

4. Submit a UCAS application

UCAS application deadline: Tuesday 15 October 2024

We take applications for all Oxford undergraduate courses through UCAS (University and Colleges Admissions Service) , which deals with all applications to higher education in the UK.

You'll need to make an account on the UCAS website, and fill in details of your academic history.

You need to apply a year before you plan to study at Oxford (unless you are applying for deferred entry). You can start working on your application anytime but you can only submit from early September. Please remember the strict submission deadline for applications through UCAS above.

You can register for the MAT and submit your UCAS form in any order, as long as they are done by the relevant deadlines.

UCAS form

For advice on filling in your UCAS form, see the UCAS website.

More general guidance is available on the University of Oxford UCAS application page.

UCAS Institution code: 033 (University of Oxford)
UCAS campus codes: College codes or 9 for an open application
UCAS course code:
  • G400 (Computer Science)
  • GG14 (Mathematics and Computer Science)
  • IV15 (Computer Science and Philosophy)
Everyone applies for the four-year course (so there is only one code for the three and four year options). You decide part way through the programme if you wish to finish at the end of the third year or continue to the fourth.

More about what our tutors are looking for.

Personal statement

See the following for advice on writing your personal statement for Computer Science.

There is also some more general advice from UCAS on writing your personal statement.

We are aware that for those applying in 2024-25 the personal statement will be replaced by a multi-question entry form. Further details on this will follow in due course.


All applications must include an academic reference. An application will be deemed incomplete without one and may not be considered. A reference will come from a teacher or someone else who is qualified to comment on your academic ability is an essential part of your UCAS application. Whilst one person completes the reference for each students, they are welcome to quote teachers from other subjects within this too. References cannot be from an employer even if you employment is related to your chosen degree subject.

UCAS provides guidance for references.

For those applying in 2023-24 there are some changes this year to the format, the reference is now split into three separate sections. The character limit is 4,000 (incl. spaces, headings and line breaks) or 47 lines of texts, whichever comes first. It is up to the referee how they divide the word count between these three sections but we would advise leaving plenty of space for section three which is where you can comment on the individual academic achievements and potential of your Oxford applicants.

  • SECTION ONE invites references to enter a general statement about their school, college or centre.
    It is strongly recommended that relevant information about school closures and disruption to cohorts is on a specific webpage created on your schools website. This site can be linked to in this section of the academic reference to ensure that most of the word count can be used to talk about the academic achievements and potential of students
  • SECTION TWO (is applicable) asks for any information about individual extenuating circumstances which may have impacted the applicant's education and achievements.
  • SECTION THREE asks references to comment on the individual academic achievements and potential, and how these relate to the course they are applying for.

UCAS have published sample references which may be useful.

Predicated grades should be included in the Education section of a candidates UCAS application, not in the applicants reference.

Predicted grades

A predicted grade is the grade of qualification an applicant’s school or college believes they’re likely to achieve in positive circumstances. Most applications that we see to our undergraduate degrees, are from students in their final year at school, and are therefore unable, at the point of application, to submit all of their final qualification scores. Using predicted grades means you can apply to study at Oxford before you have finished school (or equivalent) and you don't have to wait until all your exams are complete and your results are known.

These predicted grades are used by universities such as Oxford, as part of the admissions process, to help them understand an applicant’s potential. They are a standard part of an application to a UK university. We understand this is a lot less common in other countries. Your teacher won't be in any trouble if their prediction is wrong: but we value their professional opinion on your potential. It is really important that predicted grades are included in your application. An application would be considered incomplete without predicted grades for ongoing qualifications.

It might be that the teacher providing the reference will collate predicted grades from several of your teachers, in the same way as they often quote other teachers when writing or compiling the reference.

It's also important that you detail all of the qualifications that you hold, or are the in process of taking on the UCAS form. Please don't miss out qualifications, even if they are of a lower grade than you would like: failure to declare your qualifications can result in an application being rejected. If you are taking a qualification where you receive one overall grade, it's useful if your referee can give us an idea of individual subject grades, especially those most relevant to the course you're applying for.

If you are made an offer of a place, it will be conditional on your achieving the required grades (based on the entrance requirements for your course) in any outstanding exams. Offers are made in January and you have until the summer to complete your qualifications and meet the terms of the offer.

More guidance for providing predicted grades from UCAS

Disability/access requirements

Do tell us if you have a disability or access needs. Adjustments can be made and support requirements taken into consideration during the interview process if necessary. If you tell us what difficulties you anticipate, then we can discuss appropriate solutions. Any disability disclosure will be dealt with confidentially and sensitively. Your application will be assessed solely on academic merit. Giving us this information will not adversely affect your chances of being offered a place, but if you do come to Oxford, it will help us to ensure that everything is in place to enable you to take a full part in university life. Specific learning difficulties in particular seem disproportionately common among Computer Science students, so tutors are likely to be familiar with them.

More information about disability support is available via the Disability Advisory Service.

Special circumstances

Usually special circumstances are something that you as an individual have experienced, something that is unique to you. We take care to treat each application individually and would always take such mitigating circumstances into account, if they are brought to our attention before admissions decisions have been made.

We ask that you include any details of special circumstances in your personal statement or ask your teacher to include these in your reference.

More guidance is available on the UCAS special circumstances page (click the special circumstances tab).

If something changes

Please contact the Admissions Office at your chosen college directly (or wait until you have been informed which one you have been assigned, if you made an open application) to let them know of any changes to your academic profile that occur after your UCAS application is submitted. Examples of such changes include additional exam grades, changes to exam grades following re-marks and changes of exam boards. The only other information that colleges would take into account at this stage would be any changes to your personal circumstances since your UCAS application was submitted. Please do not ask your chosen college to consider additional references or other supporting material outside of the UCAS application.

5. Maths Admissions Test (MAT)

Registration deadline date: Friday 4 October
Date of test: late October 2024

Like all Oxford admissions tests in 2024, the MAT will be online, delivered in partnership with Pearson VUE via its established network of test centres. In 2024 there will be no charge for candidates to register for the MAT. Candidates will be able to register themselves free of charge with Pearson VUE between 15 August and 4 October.

Further details on arrangements for this test for 2025-entry will be communicated at the earliest opportunity. Please see for updates

The Mathematics Admissions Test (MAT) lasts 2 hours and 30 minutes.

This Oxford admissions test is now computer-based, and you will need to take this at an authorised test centre.

Registration to book your test will be open from Thursday 15 August 2024 and will close on Friday 4 October 2024.

The MAT is designed to be approachable for all students, including those without Further Mathematics A-level or equivalent. It aims to test the depth of mathematical understanding of a student rather than a breadth of knowledge. The mathematical knowledge and techniques required to do the questions are taken from a syllabus roughly corresponding to AS-level Maths, with a few extra topics from A-level Maths.

All Mathematics and Computer Science applicants, regardless of the course you are applying for, should answer all of the questions.

The format for this year’s test is similar to previous years, but with a different number of questions. All candidates should attempt all questions. The test consists of 27 questions. Of these, 25 are multiple-choice questions of a similar style to multiple-choice MAT questions from previous years. Each multiple-choice question is worth 2 or 3 or 4 marks, with the number of marks for each question given alongside each question. These are a similar style to multiple-choice MAT questions from previous years. There are two longer questions, worth 15 marks each, for which candidates will type responses. Candidates are not expected to type complex mathematical expressions or use any symbols beyond those included on a standard keyboard (alphanumeric characters, + - =, and similar). As with long MAT questions from previous years, candidates should expect to justify their answers or explain their reasoning for these long questions.

All applicants taking this test will be able to practise by taking a sample test in the new format online in advance of their test day. Please note that while the structure of this test does differ from previous years, all the existing resources and past papers available are still valuable preparation and we strongly recommend exploring these.

Please be aware that no calculators, formula sheets or dictionaries are permitted during the test.

The table below contains past papers and solutions. You can see below admissions statistics, to get an idea of how successful applicants scored in the MAT.

Admissions statistics summary

Additional Multiple-Choice questions

In 2020, 2021 and 2022 a multiple-choice test in the style of Q1 on the MAT was organised. This was for a small number of candidates in each year who had been shortlisted without a MAT score, and they completed the test before their interview. Due to some technical disruption to the MAT in 2023, a multiple-choice test in the style of Q1 on the MAT was administered for those who were affected. The test papers and solutions are available below for those who would like to see more multiple-choice questions in the style of Q1 on the MAT.

6. The Interviews

2024 Interview dates: TBC (usually mid-December)*

We usually interview between 2 to 3 candidiates per place. Candidates will usually have at least three interviews, two in their chosen college (or allocated college) and another in a second college. Interviewers at different colleges exchange information about candidates, to ensure that each applicant has an equal chance of a place at Oxford, no matter which college they have applied to. As a result, you might be invited for an interview at a third, or even a fourth college. If you are applying for a joint degree, you might have single-subject interviews for each part of the degree, or there may be an interview with tutors from both disciplines. Some candidates may be asked to undertake a pre-interview exercise. The interviewer may then discuss some of the questions from the exercise, with you, during your interview.

Most commonly our interviews are 30 minutes in length, sometimes our tutors start with a general question discussion, perhaps taken from your personal statement, to get to know you better, and to understand what motivates you. However most of the interview time will be taken by our tutors asking you to solve a problem, either one that you have been asked to think about in advance or one that is asked at the start of the interview. The interview will act like a mini-tutorial, with you actively discussing and exploring a problem (and your thought processes) out loud.

Interviews will normally be with two interviewers. Sometimes one interviewer will ask all the questions, whilst the other takes notes, or sometimes they might share the questioning and note-taking between them. All the interviews happen over a period of a couple of days.

We give candidates multiple interviews so that each person gets a chance to demonstrate to our tutors what they are capable of, especially if nerves are getting the better of you for one or two interviews. Tutors can discount these interviews if they don’t think that they are a fair reflection of your ability. Being invited to these extra interviews is a good sign: it shows that you have done well enough in the process so far to be seriously considered for a place. On the other hand, having interviews at just two colleges is also not a bad sign: if the tutor at your first choice college (the college you applied to or were allocated to) has indicated that you will certainly be offered a place there, then tutors at other colleges will not want to see you.

For more information, see the University of Oxford's webpage on Interviews at Oxford.

How to prepare

Our tutors are not mind readers, so if you don’t say anything our tutors can’t tell what you are thinking! The best practice you can do is getting used to talking about problems out loud. You may also want to try explaining concepts from your Maths qualification to friends and family. This not only gets you used to explaining your thoughts out loud, but also helps to consolidate your knowledge of the subject.

We very much don't want applicants to feel they need special training for our admissions. The main thing is that you do mathematics, lots of it, and that you find it interesting. We advise you to do lots of problems, on and near your syllabus, so that you really understand the mathematics you are learning.

More sample interview questions

In advance of your interview you may wish to reread your UCAS application. Our tutors may choose to start with a question about something on the personal statement section of your UCAS form to put you at ease before asking you to tackle a Maths question.

7. Offer

Shortlisted candidates for 2025 entry (or deferred)  will be told whether or not their application has been successful in January 2025. Decisions will be released via UCAS Track early in the morning. This will be followed by direct communication from the college considering your application.

Colleges, rather than the Department, will inform candidates of their decision by sending a letter or email, or sometimes both. It differs from college to college. This usually arrives in mid-January at the end of the admissions period

The correspondance you receive will explain one of two things:

  • You are made an offer of a place to study your subject. The offer will either be at a particular college, or it may be an "open offer". An open offer means that you have an offer from Oxford and are guaranteed a place if you meet the terms of any conditional offer. However, the college you will go to has not yet been specified, and will be decided after your final examination results have been published.

    If you have already completed your examinations, this offer will probably be unconditional. If you have not yet finished your final examinations, the offer will probably be conditional upon your achieving certain grades. The offer is likely to specify that you need to achieve certain grades in particular subjects and may include a requirement for evidence of proficiency in the English language.

  • Your application has, unfortunately, not been successful. For many applicants who have, until now, been the most academically successful in their school or college, it can be very dispiriting to not get an offer. Our courses are very competitive and students have done very well to get this far in the application process. It is probable that, assuming you have selected your other courses wisely, that you will go on to study at another excellent university. In a few years' time you may wish to consider applying to Oxford for further study after you have completed your first degree elsewhere.

Feeback on your application

If you wish to request feedback, you must contact the college you applied to or were allocated to. There are more details on requesting feedback.

8. Start course

By the end of August you will have completed your qualifications and got your results. Assuming you have met the conditions of your offer, you will join us in Oxford for the start of your course in October - almost a year after you first applied (or later if you applied for and received a deferred entry offer).


Over the summer you are welcome to look at recommended reading for candidates with offers.
