Most families weighing up IB vs A Levels in Year 9 or Year 10 ask the wrong question first. They ask which qualification is better. Universities worldwide respect both, and both lead to strong outcomes. The real question is which one suits your child, based on how they learn and what they want to study.
This post gives an honest account of what each route involves. It covers where they differ in practice, and how to make a decision your child will not regret halfway through Year 12.
The honest version
Neither is categorically harder or better. The IB requires breadth and sustained workload. A Levels allow depth and specialisation. The right answer depends on your child, not on which qualification looks more impressive.
What does the IB Diploma actually involve?
The International Baccalaureate Diploma Programme is a two-year qualification for students aged 16 to 18. Candidates study six subjects at once: three at Higher Level (HL) and three at Standard Level (SL). These are drawn from six groups: Language and Literature, Language Acquisition, Individuals and Societies, Sciences, Mathematics, and the Arts. Because every IB student must cover each group, nobody can opt out of humanities, sciences, or a second language entirely.
On top of those six subjects, the IB requires three core components. Theory of Knowledge (TOK) asks students to reflect on how knowledge works. The Extended Essay is a 4,000-word independent research piece. Creativity, Activity, Service (CAS) involves structured extracurricular engagement. Examiners assess all three, and they contribute to the final diploma score out of 45.
The IB workload
The IB demands a heavy workload from start to finish. Six subjects run alongside the core components throughout, so there is no quieter term. Students who struggle with time management or find breadth overwhelming often find this structure stressful. However, those who enjoy variety and feel confident across several disciplines tend to find it motivating.
What do A Levels actually involve?
A Level students choose three or four subjects and study each in depth over two years. Most take three, though four is common among those targeting highly competitive universities. Each A Level covers far more content than GCSE. The jump from Year 11 to Year 12 is substantial, and if your child is preparing for that step, our guide to the GCSE-to-A-Level transition is worth reading. Assessment is almost entirely through exams at the end of Year 13.
No subject is compulsory. A student who wants only sciences can take Chemistry, Biology, and Physics. Someone interested only in humanities can take History, English, and Politics. This freedom is the defining feature of A Levels when compared to the IB. It is the right choice for any student with a clear sense of direction who wants to go deep rather than stay broad.
The A Level workload
A Levels concentrate pressure into exam season. Most results rest entirely on papers sat in May and June of Year 13. That means two months carry two years of work. Students who perform best under clear deadlines often prefer this structure. The risk is that a bad week during exams can undo months of preparation, which creates real pressure for some. If your child is already on the A Level path, our post on A Level revision strategies covers how to manage that pressure well.
How do UK universities view IB vs A Levels?
UK universities accept both qualifications. A typical Russell Group offer might be AAA at A Level or 36 points in the IB Diploma, and both represent a broadly equivalent standard. Oxbridge and other selective programmes make offers in both formats. Neither is systematically preferred.
Studying abroad with the IB or A Levels
For students planning to apply outside the UK, particularly in the US, Canada, the Netherlands, or parts of Asia, the IB has a practical advantage. Universities worldwide recognise it immediately. A Levels, by contrast, require individual universities to assess equivalency. Students with genuine plans to study abroad will find the IB opens more doors.
For students targeting Oxbridge or specialist UK programmes such as Medicine, Law, or Engineering, A Levels remain the more common route. An applicant reading Medicine at Cambridge with Chemistry A Level walks well-trodden ground. An IB candidate with Chemistry HL is equally eligible, but needs to confirm each school’s specific entry requirements. For more on what top universities expect, see our post on what A Level grades you need for Cambridge.
How does IB content compare to A Levels subject by subject?
Most universities recognise IB Maths AA HL as broadly comparable to A Level Maths and Further Maths. Maths AA SL sits roughly level with A Level Maths alone. At HL, IB Sciences broadly match their A Level equivalents, though the internal assessment and emphasis on experimental design differ from the A Level practical endorsement. English Literature HL is a demanding course that English departments regard highly.
The IB’s requirement to study mathematics and a second language means some students study subjects they would not have chosen at A Level. This is worth thinking about honestly. A student who is weak at maths and passionate about humanities may find the compulsory maths requirement a persistent source of stress. That pressure simply does not exist on the A Level route.
Should your child choose IB or A Levels?
Choose the IB if your child enjoys variety, feels confident across multiple subjects, and has strong time management. The Extended Essay and TOK suit students who like independent, reflective work. It also suits families considering international university applications.
Choose A Levels if your child knows broadly what they want to study and prefers depth over breadth. A Levels are the natural fit for students with one or two subjects they want to pursue seriously. They also suit anyone targeting UK universities with specific subject requirements, particularly Medicine, which almost universally requires Chemistry A Level.
If your child is genuinely undecided, the practical question is straightforward. Which subjects would the IB force them to take that they would not choose at A Level? And are those subjects likely to be a strength or a source of stress across two full years?

Book a LessonWhat do most IB vs A Level guides get wrong?
Most IB vs A Level comparisons focus on prestige: which qualification looks better on a UCAS form. The honest answer is that both lead to excellent universities when the student performs well. A student who does not suit their qualification rarely performs well, regardless of its reputation.
The most important factor is fit. A student who chooses the IB because it sounds impressive but resents the compulsory breadth is less likely to produce strong grades. Equally, a student who picks A Levels because it feels like less work but then coasts without depth ends up in the same position. The qualification is only as good as the performance it enables. Performance comes from engagement, and engagement comes from choosing the right route.
