School qualifications
A-Level
GCE Advanced Level
Three subjects, studied deeply, sat at eighteen. The narrowest of the school systems and the most direct: your three choices decide, almost mechanically, which degrees will accept you.
- When
- Two years, Year 12–13 (Grade 11–12)
- Where it counts
- UK qualification, taken worldwide and accepted by universities in the UK, Saudi Arabia, the Gulf, Canada, Australia and — with credit — the US
How it works
You take three subjects — occasionally four, rarely more — over two years and are examined on all of it at the end. There is no breadth requirement: it is entirely legal, and entirely common, to take three sciences or three humanities and never write another essay or solve another equation.
That depth is the trade. An A-Level in physics covers materially more physics than IB Higher Level physics does, which is why UK universities can start their degrees where they do. The cost is that a wrong choice at sixteen is expensive, because there is no fourth subject quietly holding a door open.
AS Level is the first year taken as a standalone qualification. In most international schools it is now either skipped or sat as a progress check; some students use a fourth AS subject to broaden the profile without carrying it to A2. It carries fewer UCAS points and is not what an offer is written in.
How it is graded
A* to E, with U ungraded. A* was introduced at A2 only and requires both an A overall and around 90% across the second-year papers. Offers are written as three letters — AAA, A*AA, ABB — and are conditional: miss one grade and the place can be withdrawn, though in practice universities often still take you if you are close and they have space.
When to sit it
Exams in May/June of Year 13, results in mid-August, and UK university offers are conditional on them. The decision that matters is made in the spring of Year 11, when you pick the three. Some subjects also have a January or November session depending on the board and the country.
What it is good for
- UK, Irish, Saudi private, Emirati, Hong Kong, Singaporean, Canadian and Australian university entry — a mainstream, universally understood qualification.
- US universities too, where strong A-Levels frequently convert into a semester or more of college credit.
- Students who already know roughly which direction they are going and want to go deep rather than wide.
When it happens
Months rather than dates — the exact dates are republished every year, and the official calendar is linked below.
- May–JuneThe main series, at the end of Year 13. Offers are conditional on these results.Entries are made by your school in the winter. A subject you are not entered for cannot be sat.
- October–November and, for some boards, JanuaryAdditional series used for resits and by schools on other calendars.
- Mid-AugustResults day, and the start of Clearing in the UK. Have the backup plan ready before this, not on the day.
Mathematics and sciences
The subjects that appear by name in entry requirements. If a degree names a subject, it is almost always one of these.
Mathematics
closes doors without itOpensEngineering (all) · Physics · Computer science · Economics · Mathematics · Actuarial science · Finance · Data science · Architecture (some)
The single highest-leverage A-Level in the system. It is a hard requirement for engineering, physics, computer science and economics at every selective university, and it is required more often than students expect for psychology, geology and architecture.

Further Mathematics
OpensMathematics · Theoretical physics · Engineering at the most selective universities · Computer science · Quantitative finance
Required or strongly preferred for maths degrees at Cambridge, Imperial, Warwick and their equivalents; a genuine advantage for engineering and quantitative finance. Cannot be taken without Mathematics.

Chemistry

Required for medicine and dentistry at nearly every UK medical school and by the health colleges in Saudi Arabia. The most rigidly enforced subject requirement anywhere in the system.

Biology
OpensMedicine · Dentistry · Biomedical science · Pharmacy · Nursing · Physiotherapy · Veterinary medicine · Biochemistry · Psychology (some)
Usually the second science medical schools want after chemistry. A handful accept chemistry plus any other science; almost none accept a candidate with neither.

Psychology
OpensPsychology · Neuroscience · Social sciences · Nursing · Marketing
Counts as a science at some universities and a social science at others — which matters if you are using it as one of two required sciences. Check the specific course, not the general rule.

Computer Science
OpensComputer science · Software engineering · Cybersecurity · Artificial intelligence
Helpful and not usually required — maths is what computer science departments require. Taking computer science instead of maths is the classic mistake here.

Languages, arts and everything else
English Literature
OpensEnglish · Law · Journalism · History · Philosophy · Publishing · Education
The subject that most reliably proves you can write. That is worth more across more degrees than almost anything else here.

Arabic
OpensArabic and Middle Eastern studies · Law in Saudi Arabia · Translation · International relations
For a native speaker this is a straightforward grade and a legitimate third subject, though selective universities notice when a native language is used to fill a slot.

French, German, Spanish, Mandarin
OpensModern languages · International relations · Diplomacy · Business · Law with a language
Genuinely scarce and genuinely valued. Language A-Levels are also among the harder ones to score an A* in, which is worth knowing before you commit.

Art and Design

Architecture schools want a portfolio, and an art A-Level is how most applicants build one. Several also want maths or physics alongside it — check, because that combination has to be planned at sixteen.

Extended Project Qualification (EPQ)
OpensAny degree — it is a research qualification, not a subject
Half an A-Level in size, taken alongside the three. Some universities will drop a grade requirement for an A in it, and it is the closest A-Level equivalent of the IB Extended Essay.
Choosing well
The parts a student can act on this month.
- Work backwards from the degree, not forwards from what you enjoyed in Year 11. Find three universities you might apply to, read the actual entry requirements for the actual course, and pick the subjects that satisfy all three. This takes an hour and prevents the most expensive mistake in the system.
- If you are within reach of anything quantitative — engineering, economics, physics, computing, finance, actuarial work — take Mathematics. More degrees require maths than require any other subject, and no degree anywhere is closed off by having it.
- Chemistry plus biology plus one other is the medicine combination. Maths plus physics plus one other is the engineering combination. Both are well-trodden and neither needs to be clever.
- Avoid three subjects that are all the same shape. Three essay subjects or three sciences is fine; three business-adjacent subjects with little written or quantitative demand reads as a thin timetable to a selective admissions tutor.
- A fourth A-Level is almost never worth it. Universities make offers on three, and the fourth is paid for out of the grades you get in the other three. Take an EPQ instead if you want to show range.
What costs people a year
- A-Level Maths is a genuine step up from IGCSE, and the students who struggle most are consistently those who did not take Additional Maths and assumed a strong IGCSE grade meant readiness. If you are taking maths, spend the summer before Year 12 on it.
- Dropping a subject after the first term of Year 12 is common and usually survivable; dropping one in Year 13 is not. The syllabus does not permit catching up.
- Some Saudi and Gulf universities require a specific number of A-Levels — often three, sometimes with a named subject — and will not accept two plus an AS. Confirm the count, not just the grades.
- Conditional offers are conditional. A student holding AAA offers with ABB results is negotiating in Clearing in August, not arriving in September. Build the backup application before results day, not after.
In Saudi Arabia
A-Levels are accepted by KAUST, KFUPM, Alfaisal, Prince Sultan, Effat and the other private and semi-private universities, and by employers across the Gulf without comment. For Saudi public universities the picture is different: admission runs on the national secondary school GPA combined with Qudurat and Tahsili, so an A-Level student generally needs a Ministry of Education equivalency certificate and will often still sit the national tests. If a public university or a government scholarship is a realistic destination, find out in Year 11 exactly what equivalence your board and subject set attract — this is administrative, checkable, and routinely discovered too late.
The parts that go out of date
Everything on this page was read from the awarding body on the date below. These are the statements most likely to have moved since.
- Offer levels move year to year, and medicine and computer science have both trended upward at UK universities. Read the course page for the year you apply, not the one you looked at in Year 11.
- Which universities accept Psychology, Geography or PE as a 'science' for entry purposes varies by institution and changes; this is exactly the sort of detail that must be checked per course.
- The UCAS Tariff exists but most selective courses ignore it and state grades instead. Do not plan around points.
What sits alongside it
Almost nobody sits only one of these.
- IGCSEDetermines which A-Levels you are eligible to start, particularly in maths and the sciences.
- UCAT, LNAT, MAT and friendsUK medicine, law, maths and engineering courses add a test on top of the A-Level grades.
- IELTS / TOEFLStill usually required for a student visa even after an English-medium A-Level.
- IBThe alternative at the same stage — depth against breadth, and worth choosing deliberately.

Nothing here is sold or sponsored, and there is no affiliate link on this site. Where an awarding body publishes its own past papers, those are listed instead of a revision guide — the UCAT and LNAT consortia both state outright that paid coaching is unnecessary and unendorsed, and the same is broadly true of every exam on this page.
