Oxford and Cambridge acceptance rates by course
Cambridge computer science admitted 7.4% of its applicants in the 2025 cycle. Cambridge maths made offers to more than a quarter of its applicants and admitted fewer than half of them. Each number means something different, and the difference decides how to prepare.
Families usually ask for one number: the acceptance rate. Both universities publish enough to give a better answer, course by course, and to show where in the process applicants are lost. The figures below come from Cambridge's admissions statistics for the 2025 cycle and from Oxford's course pages, which give three-year averages for 2023 to 2025.
Cambridge, 2025 cycle
| Course | Applications | Offers | Acceptances | Accepted |
|---|---|---|---|---|
| Computer Science | 1,739 | 163 | 128 | 7.4% |
| Economics | 1,647 | 195 | 164 | 10.0% |
| Engineering | 3,263 | 392 | 335 | 10.3% |
| Mathematics | 2,032 | 555 | 258 | 12.7% |
| Chemical Engineering and Biotechnology | 541 | 92 | 77 | 14.2% |
| Natural Sciences | 2,644 | 672 | 576 | 21.8% |
| All courses | 22,513 | 4,893 | 3,669 | 16.3% |

Why maths looks easier than it is
Maths is the odd row. Cambridge made 555 offers and only 258 students took up a place. Almost every maths offer is conditional on STEP, the university's own exam sat in June: grade 1 in STEP 2 and STEP 3 alongside A*A*A at A level. Many offer-holders miss the STEP grade. So the hard part of Cambridge maths comes after the offer, in a three-hour paper that most sixth-form students have never seen anything like. Preparing for STEP from the autumn of year 13 is the single most useful thing a Cambridge maths applicant can do.
Why computer science is the hardest
Computer science had the lowest rate of any large course: 128 places for 1,739 applicants. The offer is A*A*A, but 87% of the students who arrived had A*A*A* or better. The grades in the offer are a floor; the competition happens well above it, in the TMUA and the interview.
Oxford, three-year average 2023–25
| Course | Interviewed | Successful | Places a year | Typical offer |
|---|---|---|---|---|
| Mathematics | 32% | 9% | 183 | A*A*A, A*s in Maths and Further Maths |
| Computer Science | 21% | 7% | 55 | A*AA, including A*A in Maths and Further Maths |
| Physics | 31% | 11% | 173 | A*AA |
| Engineering Science | 37% | 15% | 174 | A*A*A |

At Oxford the decisive cut is the shortlist. Four in five computer science applicants are not interviewed, and the shortlist is drawn mainly from the admissions test and the predicted grades. For 2027 entry that test is the TMUA for maths and computer science and the ESAT for physics and engineering. Oxford has stopped using its own MAT.
What the numbers mean for an applicant
- The admissions test decides more than the personal statement. At both universities the test is the first filter for maths and computer science, and it is the part of the application a strong student can improve most in six months.
- A higher offer rate is not an easier course. Cambridge maths shows why: the offer is generous and the condition is not.
- Grades are necessary, not sufficient. Almost everyone admitted to these courses has the top grades; they separate nobody.
- Apply where the course suits the student, not where the rate is highest. Interviews test how a student thinks about mathematics they have not seen, and that is very hard to fake.
