"How many APs does [university] want" isn't really a university-level question at several of the UK's most-applied-to schools in our own dataset -- it's a course-level one. The same university can publish a real, official 3-AP route for one degree and a real 5-AP route for another, or set a harder AP-score combination for one version of a course than for its closest sibling. This is the "why does it change" half of our broader piece on how many AP exams UK universities actually ask for.

Imperial: the 3-or-5 trade is nearly universal, but the numbers inside it move

Imperial College London publishes the same basic shape on almost every course page in our dataset -- 5 AP exams alone, or 3 AP exams plus a test score -- but the specific numbers inside that shape genuinely differ by course:

  • Physics BSc: 5 APs at grade 5, or 3 APs at grade 5 plus SAT 1480+/ACT 33+.
  • Chemistry BSc: 5 APs at 5,5,5,4,4, or 3 APs at 5,5,4 plus a lower SAT 1460+/ACT 31+.
  • Electrical and Electronic Engineering MEng: 5 APs at grade 5 including Calculus BC and both AP Physics C exams, or 3 APs at grade 5 plus SAT 1480+/ACT 33+.
  • Electrical and Electronic Engineering with Management MEng: a real, tougher version of the same degree -- 5 APs at 5,5,5,5,5 (all five at the top score) including Calculus BC, both Physics C exams, and two further relevant subjects, or 3 APs at 5,5,5 plus SAT 1480+/ACT 33+. Adding the Management year raises the AP bar on the same core engineering degree.

Not every Imperial course offers the trade at all. Computing BEng's own page states plainly: "We do not accept ACT or SAT scores for entry at undergraduate level" -- US applicants there are assessed on AP exams only, a fixed 5,5,5 including Calculus BC, with no test-score alternative to reduce the count. And two of Imperial's engineering courses -- Aeronautical Engineering MEng and Biomedical Engineering MEng -- are genuine gaps in the public record: both pages were checked twice specifically for an American-qualifications section, and neither names an AP, SAT, or ACT figure at all, a real contrast with every other Imperial engineering course in our dataset.

Oxford: the same trade, tied to A-level tier rather than course family

University of Oxford's Computer Science and Economics and Management pages both publish an identical structure -- 4 APs at grade 5 alone, or 3 APs at grade 5 plus a test score -- because both sit in the same A*AA offer tier. Oxford's Mathematics and Mathematics and Philosophy pages step the AP count's required subject up (Calculus BC specifically) while keeping the same 4-alone-or-3-plus-test shape. The trade itself doesn't change across these courses; what changes is which subject has to be inside the 3 or 4.

Cambridge and LSE: no trade, but still two different tiers

University of Cambridge doesn't offer a 3-vs-5 trade at all -- every course in our dataset requires the same 5 APs at grade 5, regardless of tier. What moves instead is the accompanying SAT/ACT figure: 1500/33 for "Science & Economics" courses, 1460/32 for everything else. London School of Economics's Law LLB page runs a similar two-band structure on the AP side specifically: 5 APs at grade 5 for its most competitive offer band, or 3 APs at grade 5 plus 2 more at grade 4 for a documented lower band -- a real reduction in required score, not exam count, covered in more detail in our piece on UK universities that accept an AP score of 4.

What this means for you

  • A university's AP policy is rarely one number -- check the specific course, especially at Imperial and Oxford, where a real 3-vs-5 trade exists but the numbers inside it shift by department.
  • Adding a "with Management" or similarly specialised year to an engineering degree can raise the AP bar, as Imperial's Electrical and Electronic Engineering with Management page shows against its plain-EEE sibling.
  • Not every course at a trade-friendly university actually offers the trade -- Imperial's Computing BEng requires a fixed AP-only route with no SAT/ACT alternative at all, unlike most of Imperial's other courses in our dataset.
  • If a course's own page doesn't state an AP/SAT/ACT figure, don't assume it's zero -- Imperial's Aeronautical and Biomedical Engineering pages, checked twice, are genuine gaps in the public record, not confirmed no-AP-needed courses.
