Overview
There is no single "best" set of A-Levels for international students — the strongest choice keeps your degree options open, satisfies the subject and English-language requirements of your target universities, and plays to your genuine academic strengths. As a rule, three solid A-Levels chosen with a course in mind beat four scattered subjects. If you are undecided about your degree or country, a balanced, facilitating combination gives you the widest reach while you decide.
Start with your destination
Different systems value A-Levels slightly differently, so let your target universities lead. UK universities usually make offers in specific A-Level grades and often name required subjects for a course, so their published entry requirements are your primary map. US universities treat A-Levels as strong evidence of rigour but assess you holistically alongside essays, activities and sometimes standardised tests, and may award credit for high grades. Other global universities vary widely. Because requirements change year to year, you should verify each university's current criteria directly rather than relying on general advice or older forum posts.
| Priority | UK universities | US universities |
|---|---|---|
| How A-Levels are used | Grade-based conditional offers | Part of a holistic review |
| Subject requirements | Often specific, course-led | Usually flexible, breadth valued |
| Number expected | Typically three | Three, plus wider profile |
| English evidence | Often required for non-natives | Often required for non-natives |
| Extra tests | Some courses (e.g. admissions tests) | SAT/ACT at some institutions |
Keep your options open
If you are not yet certain of your degree, favour subjects that keep the most doors open. Traditional, essay- or maths-heavy "facilitating" subjects — such as Mathematics, the sciences, English, History, Economics and a language — are accepted for a wide range of courses and rarely rule anything out. Avoid locking yourself into a niche combination too early unless you are confident of the degree it serves. For structured guidance on combinations, see [best A-Level subject combinations](/blog/best-a-level-subject-combinations-2026) and the broader [subject-choice guide](/guides/subject-choice).
Check subject and English-language requirements
Two requirements catch international students out. First, many degrees name essential subjects — for example, Mathematics for engineering or economics, Chemistry for medicine — so a missing subject can quietly close a course before you apply. Second, universities almost always require evidence of English proficiency for non-native speakers, sometimes accepting a strong IGCSE or A-Level English grade and sometimes requiring a separate test. Both requirements vary by institution and change over time, so confirm them directly with each university early, before you finalise your A-Level choices.
Play to your strengths
Universities care about grades, and top grades in subjects you are genuinely good at beat mediocre grades in subjects chosen only to impress. Pick subjects you can excel in and sustain for two years, and be honest about workload — for instance, whether you want [three or four A-Levels](/blog/how-many-a-levels-do-you-need). If you are choosing between systems entirely, it is also worth reading [IB vs A-Level](/blog/ib-vs-a-level) and, for US-bound students, [A-Level vs AP](/blog/a-level-vs-ap), since the qualification itself can matter as much as the subjects.
Practise the way you will be marked
A-Levels are graded against published mark schemes, and examiners reward specific points, structured argument and correct command-word responses rather than general effort. International students sometimes lose marks not on knowledge but on exam technique — how a question is answered for that board. The most reliable fix is to work through real past papers under timed conditions and check each answer against the mark scheme. You can [mark answers instantly against the scheme](/mark) to see exactly where marks are being dropped and close the gap before the real exam.
Frequently asked questions
This section covers Frequently asked questions — ranked by what Cambridge examiners return to most often in past papers.
How many A-Levels do international students need?
Three strong A-Levels are the standard expectation for most universities, and quality matters more than quantity. A fourth can help for very competitive courses but is rarely required — check each target university's stated requirements.
Do I need specific subjects for my degree?
Often yes. Many courses name essential subjects, so a missing one can rule you out before you apply. Verify the required and recommended subjects directly with each university early in your choice.
Will I need an English test as well as English A-Level?
Sometimes. Many universities require separate proof of English for non-native speakers, though some accept a strong English qualification instead. Requirements differ by institution, so confirm what each one accepts.
Are A-Levels accepted by US universities?
Yes, US universities generally recognise A-Levels as rigorous and may award credit for high grades, but they assess applications holistically. Some also expect standardised tests, so check each institution's current policy.
