TL;DR: Oxford does not mention GPA in its US entry requirements. It converts your application into AP scores plus an SAT or ACT, on a three-tier scale set by the course. Cambridge is different. It has a published section titled “High School Diploma GPA Requirement” that asks for very strong performance, gives no number, and encourages your counsellor to explain your GPA in the reference.
If you have searched for the GPA you need for Oxford or Cambridge, you have probably found a number. Somebody’s blog quotes a range. Somebody else quotes a slightly different one.
Neither university publishes one.
That sounds like bad news. It is the opposite, because what they publish instead is far more specific than a GPA ever was. Both tell you exactly what they want, course by course, in writing, on their own websites. You just have to know where to look.
Here is what I found when I went through both.
What GPA do you need for Oxford or Cambridge?
There is no published GPA threshold at either university. But the two handle this very differently, and most guides collapse them into one answer.
Oxford does not mention GPA in its US entry requirements, or in the course requirements I checked. What it asks for instead is AP scores, with an SAT or ACT standing in for a fourth AP.
Cambridge does require a GPA. Its US entry requirements page carries a section headed “High School Diploma GPA Requirement,” and what it says is this: very strong performance within the High School Diploma is expected. No number. Cambridge then encourages your referee to provide statements that give context to your GPA score inside the school reference.
Read that twice. Cambridge is telling you the number matters and that the number alone will not speak for itself. Your counsellor has to explain it.
What does Oxford actually require from US applicants?
Oxford runs a three-tier scale. The tier you fall into depends on the A-Level offer for your course.
| If your course’s offer is | You need |
|---|---|
| A*A*A | Four APs at grade 5, OR three APs at grade 5 plus ACT 33+ or SAT 1480+ |
| A*AA | Four APs at grade 5, OR three APs at grade 5 plus ACT 32+ or SAT 1470+ |
| AAA | Four APs at grade 5, OR three APs at grade 5 plus ACT 31+ or SAT 1460+ |
In every tier the APs must include any subjects required for your course. The optional essay is not required for either test.
Full details: https://www.ox.ac.uk/admissions/undergraduate/courses/admissions-requirements/international-qualifications
Three rules on that page catch people out.
Calculus AB and Calculus BC cannot count as two subjects. Not as separate tests, and not by taking the AB sub-score inside Calculus BC. One counts, not both.
AP Pre-Calculus cannot fulfil a maths requirement for courses that specify maths. It can count toward one of your three or four grade 5s for other courses.
No superscoring. Your SAT Reading and Writing and Math scores must come from the same sitting. Same for the ACT, where Oxford only considers the Highest Full Battery score. You are also asked to declare every score you have, including retakes, and every test you still plan to take.
What does Cambridge require from US applicants?
More, and it says so plainly. A US High School Diploma on its own is not considered suitable preparation for entry.
Cambridge asks for all three of the following:
- A minimum of five APs at grade 5, in subjects related to your course.
- A high SAT or ACT score.
- A high overall GPA in your High School Diploma.
The test thresholds are published. For most science courses, meaning Chemical Engineering, Computer Science, Engineering, Mathematics, Medicine, Natural Sciences, Psychological and Behavioural Sciences and Veterinary Medicine, plus Economics, you need SAT 1500 combined with Maths 750 or above, or ACT 33. Science applicants should also reach an ACT Science score of at least 33.
For every other course it is SAT 1460 with Evidence-Based Reading and Writing at 730 or above, or ACT 32.
Your scores must have been achieved within two years of matriculation. Full page: https://www.undergraduate.study.cam.ac.uk/international-students/international-entry-requirements
Compare the two side by side and the gap is obvious.
| Oxford | Cambridge | |
|---|---|---|
| APs required | 3 or 4 at grade 5 | 5 or more at grade 5 |
| SAT/ACT | Only if taking 3 APs | Always |
| GPA | Not mentioned | Required, no number published |
| Diploma alone | Not sufficient | Explicitly not sufficient |
What are the actual A-Level offers behind these numbers?
Since the AP tier is set by the A-Level offer, it helps to see real ones.
Three A grades is Oxford’s minimum standard offer for A-Level candidates, and many courses, particularly in the sciences, require at least one A*. Mathematics asks for A*A*A with the A*s in Maths and Further Maths, if Further Maths is available to you. Chemistry asks for A*A*A with both A*s in science or maths subjects, and separately requires Chemistry and Maths as subjects. Physics asks for A*AA with the A* in Physics, Maths or Further Maths.

https://www.ox.ac.uk/admissions/undergraduate/courses/course-listing/chemistry
https://www.ox.ac.uk/admissions/undergraduate/courses/course-listing/physics
At Cambridge, Economics sets a minimum of A*A*A, with an IB equivalent of 41 to 42 points including 776 at Higher Level. Philosophy sets A*AA on the same IB range.
Here is the part that matters more than the minimum. Cambridge publishes what its entrants actually achieved. Among Economics students who took A-Levels and started in 2018, 2019 and 2023, 80% had at least A*A*A*. The minimum offer is A*A*A. The typical entrant is a full grade above it. In Philosophy, where the minimum is A*AA, 64% of entrants had at least A*A*A.
Economics took 164 students in the 2025 cycle at ten applications per place. Philosophy took 42, at five per place.

https://www.undergraduate.study.cam.ac.uk/courses/philosophy-ba-hons
For scale on the Oxford side, 87.2% of UK students admitted in 2025 held A*AA or better, and 47.1% held three A* grades or better. Both figures come from Oxford’s Annual Admissions Statistical Report 2026: https://assets-oxweb.admin.ox.ac.uk/2026-07/Undergraduate%20Admissions%20Report%202026_0.pdf
What if my school does not offer the APs I need?
Both universities address this, and their answers are not the same.
Cambridge: if your school offers fewer than five APs, self-enrol onto additional AP tests. You can sit an AP test without taking the course. Cambridge states this directly and says it will take your school’s policies into account.
Oxford, university-wide: if you are applying for a course requiring maths you should take Calculus BC where you can, but courses will accept Calculus AB where you cannot.
Oxford Mathematics specifically goes further. Its Mathematical Institute page says that where an applicant cannot take AP Calculus BC, it may consider their application on their strength in Mathematics as shown through the courses they are taking, through its admissions test, and at interview if shortlisted: https://www.maths.ox.ac.uk/study-here/undergraduate-study/our-offer
One thing to know about that test. The page above still names the Mathematics Admissions Test. The department’s own test page says the MAT ran from 2007 to 2025, will not take place for the 2026 admissions round, and has been replaced by the Test of Mathematics for University Admission. All applicants for Maths, Computer Science and joint honours must sit the TMUA. It runs 12 to 16 October 2026, lasts two and a half hours across two papers of 20 multiple-choice questions, allows no calculators, and is sat at Pearson VUE centres. Oxford shortlists around three applicants per place on the strength of it: https://www.maths.ox.ac.uk/study-here/undergraduate-study/tmua
The TMUA is set with the aim of being approachable by students who have not taken Further Maths A-Level, and by students from other education systems. Which matters if you are applying from a US high school.
So what actually separates applicants?
Not the transcript. Every serious applicant has one.
Both universities decide before your final results exist. Offers are conditional, made in advance, and your referee’s predicted grades stand in for results you have not sat yet. Cambridge says this explicitly on its US page: admission operates on a pre-qualification basis, and predicted grades help the University understand each applicant’s potential.
Which puts unusual weight on the parts of the application that are already finished when you apply. Your personal statement. Your reference. Your admissions test. Your interview.
There is one more line on Cambridge’s US page worth sitting with. On AP Capstone, Cambridge says it welcomes the qualification and encourages applicants to take AP Research and Seminar, because it helps develop independent study and research skills valuable for higher education. It then says Capstone scores will not usually count toward the five grade 5s.
So Cambridge is recommending a qualification that does not help you meet the numbers. That tells you what it is looking for underneath them.
Oxford says something similar about Capstone: it will not be a condition of any offer, but the University recognises that it may give applicants the chance to develop research and academic skills relevant to higher education.
Key Takeaways
- Neither university publishes a GPA cutoff. Oxford does not mention GPA in its US entry requirements.
- Cambridge has a GPA requirement section that asks for very strong performance without stating a number, and encourages your counsellor to give it context in the reference.
- Oxford’s AP requirement is tiered by the course’s A-Level offer: four grade 5s, or three grade 5s plus ACT 33/32/31 or SAT 1480/1470/1460 depending on the tier.
- Cambridge asks for five or more APs at grade 5, plus an SAT or ACT score, plus a strong GPA. All three.
- Cambridge SAT thresholds are 1500 with Maths 750+ for sciences and Economics, and 1460 with EBRW 730+ for everything else.
- Calculus AB and BC cannot both count at Oxford. Neither university allows superscoring.
- Published minimums understate the real bar. Cambridge Economics asks for A*A*A; 80% of its entrants had A*A*A*.
- Oxford’s MAT has been retired. Maths, Computer Science and joint honours applicants sit the TMUA from the 2026 round.
- If your school offers fewer than five APs, Cambridge tells you to self-enrol. AP tests can be sat without the course.
Frequently Asked Questions
Will a 4.0 GPA get me into Oxford or Cambridge?
No, and at Oxford it is not part of the published US requirements at all. At Cambridge a strong GPA is one of three things asked for, alongside five APs at grade 5 and a high SAT or ACT. Cambridge also states that a High School Diploma on its own is not suitable preparation for entry.
Does Oxford require the SAT or ACT from US applicants?
Only if you are taking three APs rather than four. Four APs at grade 5 satisfies the requirement on its own. With three, you need ACT 33 or SAT 1480 for a course requiring A*A*A, and slightly lower for A*AA and AAA courses.
What if my school does not offer the APs I need?
Cambridge tells you to self-enrol onto additional AP tests, which you can sit without taking the course. Oxford accepts Calculus AB where Calculus BC is unavailable, and Oxford Mathematics may instead assess your maths through your current courses, its admissions test, and interview.
Does Oxford still run the MAT?
No. The Mathematical Institute states that the MAT ran from 2007 to 2025 and will not take place for the 2026 admissions round. All Maths, Computer Science and joint honours applicants take the TMUA instead.
Can I superscore my SAT?
No, at either university. Oxford requires your Reading and Writing and Math scores from a single sitting and considers only the ACT Highest Full Battery. Cambridge requires you to disclose every test taken, including retakes, and reserves the right to contact College Board, ACT or your school to confirm.
How long are my scores valid at Cambridge?
Your AP, SAT and ACT results should have been achieved within two years of matriculating.
What if I am taking A-Levels or the IB instead?
Then none of this applies, and both universities set offers directly in your qualification’s own terms. We compare the two systems here: https://oxford-research.uk.com/a-levels-vs-ib-uk-university-applications
Conclusion
The honest answer to “what GPA do I need” is that Oxford will not look at it and Cambridge will not tell you the number.
What both will tell you, in detail, is everything else. Which APs. Which score. Which subjects. Which sitting. Which test, in a year when one of them has just been replaced. It is all published, course by course, and almost nobody applying from a US high school reads it before they start.
So read your course’s page first. Then work on the part of the application that is not a number at all, because the offer gets decided before your final grades exist, on your statement, your reference and how you think in an interview room.
