Free IB Subject Chooser 2026 — Match IB Diploma HL & SL Subjects to 25 University Degrees

Pick your target university degree and we'll show the IB Diploma subject mix you need — HL vs SL splits, Maths AA vs AI guidance, and degree-specific country variations (e.g. Cambridge Maths needs AA HL with a 7; Singapore engineering doesn't accept AI HL). 25 degrees from Medicine to Modern Languages.

What do you want to study at university?

Pick the degree you're aiming for. We'll show you which IB Diploma subjects you need to take. If you're undecided between two, pick the stricter one — its subjects usually keep the other open too.

IB Diploma Subject Chooser FAQ

Quick answers about picking IB Diploma subjects for university.

How does the IB Diploma subject chooser work?

Pick the university degree you're aiming for. We map that back to the IB Diploma subjects you need to take — sorted into required (no offer without them), strongly recommended, recommended and useful complements — plus the typical UK offer (or IB total), the famous flagship-university exceptions (Oxbridge / LSE / Imperial), and country-specific notes where the answer materially differs (US / Singapore / Australia).

Why does IB Diploma subject choice matter so much?

IB Diploma is structured (3 HL + 3 SL across 6 groups), but you still need the right HL choices for your target degree. The Maths AA vs AI distinction is the most important call: AA HL is required for selective Engineering / CS / Maths / Economics; AI HL is fine for less quantitative degrees but rules out the most competitive courses.

Are there subjects I should NOT take at IB Diploma for my target degree?

Yes. For selective degrees, universities flag certain subjects as 'soft' or 'non-facilitating' — they don't actively hurt by themselves but can make a 3-subject combination uncompetitive. Critical Thinking and General Studies are commonly excluded from offers entirely. A-level Law is generally not preferred for LLB degrees (top schools want a different rigorous subject). The result page flags the avoid-list per degree.

Do all universities accept the same IB Diploma combination?

Mostly yes for required subjects, but flagship universities (Oxford, Cambridge, Imperial, LSE, UCL, NUS, NTU, ETH Zurich, MIT, Stanford) often layer on additional requirements — Cambridge Engineering wants Further Maths; LSE Economics wants A* in Maths; Oxford Medicine doesn't accept Maths/Further Maths as your only quantitative subject. The result page surfaces the famous exceptions. For your final shortlist, always cross-check each university's specific course page.

What about US / Australian / Singapore universities?

US Medicine and Law are post-graduate degrees — different pathway entirely. US universities are generally more flexible about specific subjects (they look at GPA + SAT/ACT + AP credits holistically). Australian universities mirror UK requirements closely for selective degrees like Engineering and Medicine. Singapore universities (NUS, NTU, SMU) are often as strict as the UK Russell Group. The result page flags these country variations for each degree.

How accurate is this advice?

The recommendations follow each degree's published entry requirements at the major UK and IB-receiving universities, refreshed annually. Requirements DO drift — flagship universities sometimes tighten or loosen what they accept. Always cross-check the specific course page on the university's own admissions site before locking in your subject choices. This tool is the orientation; the university's own course page is the contract.

What if I want to keep multiple degree pathways open?

Smart move — most students change their mind between Year 11 and Year 13. The strongest 'open-doors' IB Diploma combinations are: Chemistry HL + Biology HL + Maths AA HL (keeps Medicine, Dentistry, Veterinary, Biology open); Physics HL + Maths AA HL + Chemistry HL (keeps Engineering, Physics, Chemistry, CS open); History HL + English A HL + Economics HL (keeps Law, PPE, Politics, Business open).

Can Tutopiya help me decide?
