Is IB or A-Levels better for UK university admissions?
For UK universities specifically, A-Levels are the more common route — around 85% of Oxford's 2024 entrants held A-Levels — but IB is fully accepted and, after controlling for ability, HESA/IBO data shows IB students are actually more likely to reach a top-20 UK university. The honest answer: neither is universally 'better'; A-Levels suit a student who already knows their subject and wants maximum depth, while IB suits a student keeping options open or targeting the US too.
“A-Levels are the well-trodden path into UK universities, but "more common" is not the same as "required" — the IB is fully accepted, and once you control for ability it actually correlates with stronger odds of reaching a top-20 UK institution.”
UK admissions tutors know exactly what A*A*A means and have decades of data correlating A-Level grades with degree outcomes — there is no translation friction. IB offers are converted (typically 40-42 points with 7,7,6 at Higher Level for Oxbridge), and the conversion is well-established.
The deciding factors are your child's profile and target geography, not a blanket ranking. A student set on Cambridge Maths benefits from the full A-Level depth of Maths + Further Maths + Physics, which the IB's breadth requirement structurally prevents. A student who may also apply to US universities benefits from the IB's research essay, breadth, and service components that map onto US holistic admissions.
