Understand the idea.
Then make it work.
YOUR ROUTE INTO COMPUTER SCIENCE
A strong application begins with the right preparation. Mathematics matters at both universities; a coding portfolio does not replace required subjects.
Compare the Oxford choice with Cambridge Computer Science. Its course, requirements and admissions context update below.
Study location, qualification and fee status are separate.
2027 ENTRY · CHECKED 26 OCTOBER 2026766 HL · Mathematics HL 7
Both Mathematics AA HL and AI HL are accepted without preference. School Computer Science is not required.
The same IB baseline applies to all three Oxford routes.
Official requirement guidance ↗776 HL · normally Mathematics AA HL 7
Cambridge normally requires Mathematics AA HL. If your school cannot offer it, contact the College before applying.
Colleges may specify additional subjects or higher grades. Check your exact HL combination.
Official requirement guidance ↗Choose a verified example to see meaningful differences. The selection also refines the Cambridge College fee below. It does not establish your fee status or make an eligibility decision.
College guidance ↗Oxford CS / CS & Philosophy: A*AA. Maths & CS: A*A*A. Full Further Maths is normally expected where available. All three: IB 39, 766 HL, Maths HL 7, with AA or AI accepted without preference.
Cambridge: A*A*A or IB 41–42, 776 HL. Maths AA HL is normally required at IB; take Further Maths to AS/A level if the school offers it. Churchill publishes A*A*A* / 43 and 777; check the College’s full conditions.
Oxford AP: four 5s including Calculus BC and two other maths/science subjects, or three such 5s plus SAT 1470/Maths 770 or ACT 32. Maths & CS uses SAT 1480/Maths 770 or ACT 33 for the three-AP route. Cambridge: normally five relevant AP 5s, strong school results and SAT 1500/Maths 750 or ACT 33; science applicants using ACT also need Science 33.
National qualifications: use the exact award and course-grade band. For example, Oxford’s CBSE baseline is three A1s/two A2s for CS, or four A1s/one A2 for Maths & CS, including required subjects. Cambridge CS is not a CBSE-only accepted route. Mixed packages and unlisted awards need university/College advice.
BEGIN WITH THE EDUCATION
Why does an algorithm work? What can a machine compute? How do we build a system we can trust? Both universities connect mathematical ideas with practical work. The course structure is a better guide than the shorthand “Oxford theory, Cambridge practice”.
You cannot ordinarily apply to Oxford and Cambridge in the same undergraduate admissions year. Choose the education before building the application around it.
Read the application guidance ↗THE COURSES, SIDE BY SIDE
The balance of subjects, timing of options and shape of project work can make the decision clearer.
The main Computer Science degrees, side by side. Both combine mathematical reasoning and practical work.
Change Oxford route ↑Mathematical foundations and practical computing, with options beginning in second year.
G400 · 3-year BA / 4-year MCompSci
A broad compulsory foundation across computing, with options in third year and a required individual project.
G400 · 3-year BA (Hons) / BA + MEng after year 4
WHICH WOULD SUIT YOU?
you want Computer Science at the centre of the degree, options from second year and a possible advanced project year.
you value a broad common foundation and a substantial individual project within the three-year degree.
The fit notes are our interpretation of the published courses. Cambridge’s MEng normally requires a First in Part II and College support; Oxford currently requires a 2:1 at the end of year three. Check current rules and future option availability. Cambridge progression ↗
GG14 · BA / MMathCompSci. Approximately half mathematics and half computing initially, with more choice later. A good fit if you want university mathematics for its own sake. Its A-level and some national/AP requirements are higher than main CS.
Compare Maths & CS ↑IV15 · BA / MCompPhil. Initially about 50:50, connecting computing and philosophical argument through logic, computability and intelligence. Expect serious reading and essays as well as technical work; school Philosophy is not required.
Compare CS & Philosophy ↑THE ADMISSIONS TESTS
TMUA at both universities. Peterhouse and Trinity also require CSAT for shortlisted Computer Science applicants.
Oxford replaced MAT for the 2026 application round, for 2027 entry. Old MAT marks and offer-holder means cannot be converted into a TMUA threshold.
Official test guidance ↗CS does not have Mathematics’ universal STEP condition. Some individual offers may include STEP, including Christ’s qualification-specific exception. Trinity CS requires October TMUA for overseas applicants too.
Official test guidance ↗Standard 2027-entry dates have passed: booking closed 28 September 2026 at 18:00 BST; testing was 12–16 October, with TMUA only on 15–16 October in China, Hong Kong and Macau. Results are due 16 November 2026. These are reference-cycle dates, not a late application window.
TMUA costs £78 in the UK/Republic of Ireland, £133 elsewhere. Book a Pearson centre separately from UCAS, check ID requirements and request access arrangements before booking. Eligible UK candidates can apply for the provider’s bursary.
January is not a general retake. Eligible Cambridge mature-College January applicants may use 4–8 January 2027 (8 January only in China/Hong Kong/Macau). Booking opens 28 October at 15:00 GMT; access requests close 7 December, bursaries 14 December and booking 21 December at 18:00 GMT. One sitting per cycle. Confirm eligibility first.
CSAT is additional at Peterhouse and Trinity. Prepare for written mathematical/computational reasoning, not a test of how many programming languages you know. Follow the current College invitation for the date, platform, time zone, upload process and access arrangements.
The latest clearly dated provider instructions verified in our research were for 2025, not the coming December round. We have therefore not reused those dates or the historical format as confirmed 2026 instructions.
CS does not have Mathematics’ standard STEP 2/3 condition. However, individual offers can differ: Christ’s India guidance says STEP may be included where equivalent Maths/Further Maths preparation is not demonstrated. Confirm the exact package directly. Trinity’s overseas TMUA exception for Mathematics does not apply to its CS course.
ADMISSIONS IN CONTEXT
Grades are a starting point. Select the applicant context, then read the reporting group beside every figure.
International context · source populations retained
549 applications · 169 shortlisted · 78 offers. EU + other non-UK groups combined, calculated from the 2025–26 departmental report.
Domicile is not fee status or nationality. This combines CS, Maths & CS and CS & Philosophy; it is not a main-CS international rate.
Published admissions source ↗The 2025 course totals cover all domiciles: 1,739 applications, 163 offers and 128 acceptances. A matched international/Home-fee breakdown was not verified here.
The Home/UK-school subset is not every Home applicant. Subtracting it from the total would not isolate international applicants.
Published admissions source ↗Admissions groups and fee status are different. These figures do not predict an individual outcome. We have not inferred an international Cambridge CS rate from a differently defined school subset, or borrowed Medicine’s overseas place limits.
Oxford, 2025–26 departmental round: CS 531 applications / 144 shortlisted / 58 offers; Maths & CS 564 / 206 / 90; CS & Philosophy 118 / 46 / 15. These are principally for 2026 entry with some deferred 2027 offers. Joint applicants receiving a single-subject offer remain in their original applied-course row.
Oxford, all three CS routes combined: UK domicile 664 applications / 227 shortlisted / 85 offers; EU 78 / 18 / 6; outside UK/EU 471 / 151 / 72. The displayed non-UK row adds the latter two. It is not an overseas fee-status or main-CS-only rate.
Cambridge, 2025 cycle: 1,739 applications / 163 offers / 128 acceptances. Offers/applications is 9.4%; acceptances/applications is 7.4%. The Home/UK-school subset (1,114 / 100 / 89) cannot be subtracted to isolate all international applicants.
Oxford’s course-page three-year averages and the single-round offers above measure different outcomes. Historical Cambridge College TMUA means also vary with the cohort: a mean is not a minimum, and College comparisons do not establish an easier route. No personal chance calculator is implied.
THE FULL COST
Tuition is only the beginning. Cambridge overseas fees include a separate College teaching fee; living costs belong in both budgets.

College fees: published undergraduate range £12,885–£15,950. Accommodation belongs in living costs, not the teaching fee.
Planning illustrations, not a final quote. Whole-course figures simply multiply the annual estimate; they exclude future increases, visa/health charges, flights and extra costs. Oxford fees usually rise annually. Cambridge normally fixes international University tuition for the course, but College fee policies differ. A fourth year needs academic progression. School location and nationality alone do not determine fee status.
Full international undergraduate scholarships are scarce. Cambridge says most support is partial and means-tested. Cambridge Trust applications normally follow a College offer; country awards can have earlier deadlines. Hong Kong’s Prince Philip Scholarship needs an application alongside the Cambridge application.
Reach Oxford has restricted country and circumstance eligibility, with around 2–3 awards a year across subjects. CS is within its subject scope. An Oxford offer is needed first; the published 2027 scholarship deadline is 26 January 2027, with detailed instructions due in January.
Ask whether an award covers College fees, fee increases, vacation living and a fourth year, and check renewal conditions. For government sponsorship, read service bonds and rules about joint degrees or changing course. Do not deduct a prospective award from the budget before it has been granted.
Oxford’s current guidance distinguishes new borrowing regulations from grandfathered arrangements. A new entrant should not assume the old unlimited Parent PLUS model. Its new-regulations table lists a $20,000 annual / $65,000 aggregate Parent PLUS limit per dependent student, subject to eligibility and regulatory updates.
Ask the university loans team to confirm the exact course, fourth-year classification, prior borrowing, dependent status and disbursement dates. MEng or MCompSci in the title does not itself establish a US loan category. Plan for currency movement and cash needed before funds arrive.
Oxford US-loans guidance ↗PREPARATION
Useful preparation leaves you able to explain a decision, question a result and try a better approach.
Build the required subject foundations, then practise applying them to unfamiliar problems. Keep a record of why an answer failed, not just the correct answer.
Compare two algorithms, explore a graph problem or test a simple model. Understand the code, its assumptions and its limits. Be honest about any AI assistance.
Discuss your work and respond to a hint. A carefully understood project or argument is more useful than a long list of technologies or certificates.
THE QUESTIONS FAMILIES ASK
The subject, the application and the possibilities beyond it.
School CS is not a universal prerequisite. Required mathematics comes first. No universal GitHub, medal, internship or publication requirement is identified in the cited course guidance. A small project you understand can be useful evidence; an impressive title cannot replace explaining your own work.
Start with foundations: algorithms, probability, linear algebra, programming, systems and logic. Both universities offer theoretical and practical study. Look at compulsory papers, later options and projects; no future option, internship, job or salary is guaranteed. Oxford CS & Philosophy adds substantial philosophical work, rather than just an AI ethics module.
Ordinary undergraduate applicants cannot apply to Oxford and Cambridge in the same admissions year, and Oxford allows one course choice. Apply for the course you want to study. A different-course offer or later switch is discretionary and must not be assumed.
Pending examinations can form part of a conditional offer, with credible predictions. TMUA and application deadlines still apply. UK offers can remain conditional until summer results; coordinate US deposits and commitments around that uncertainty. SAT or ACT does not replace TMUA.
The BA is a science degree in this subject. Cambridge’s fourth-year MEng continues undergraduate study; it is not automatic or the separate graduate MPhil. Oxford awards MCompSci, MMathCompSci or MCompPhil according to route. Confirm overseas graduate-programme recognition, accreditation and loan classification with the relevant institution rather than inferring it from the title.
A basic modern laptop is sufficient in Cambridge’s departmental preparation guidance; ask about facilities and access needs before buying specialist hardware. Neither an expensive machine nor a paid course is a published admissions prerequisite. Free official test and subject resources are available.
Do not assume a transfer into year two. Oxford does not accept ordinary mid-course transfers, and applications to restart while at a UK university are normally exceptional. Cambridge has specific restrictions and exceptions. A year of overseas university study may be considered as preparation in some national routes, but does not establish a right to advanced entry.
Do not build the budget around this. Cambridge does not expect undergraduate term-time paid work. Student visa restrictions are separate and do not permit self-employment or business activity. Online freelance work, commercial apps or overseas clients are not automatic exceptions; ask the university immigration team about the exact activity.
Research checked 26 October 2026 for the 2027-entry reference. Historical cycles retain their original labels. Requirements do not determine individual eligibility or predict admission. Academic review is pending; current university guidance, College instructions and the actual offer take priority.
The report flags unverified CSAT 2026 administration, mixed-qualification cases and the absence of a matched Cambridge international CS funnel. Where guidance is unclear, the relevant College or department should resolve the exact applicant case.
