IB Diploma vs A-Level: Which Should You Choose?
Both the IB Diploma and A-Levels are respected worldwide for university admission. The core trade-off is breadth versus depth: the IB keeps you across six subject groups plus a core, while A-Levels let you specialise deeply in three or four subjects.
| IB Diploma | A-Level | |
|---|---|---|
| Structure | 6 subjects + core (TOK, Extended Essay, CAS) | Typically 3–4 chosen subjects |
| Approach | Broad, interdisciplinary | Deep specialisation |
| Duration | 2 years, fixed framework | 2 years, modular/linear by board |
| Scoring | Out of 45 (24 to pass) | A*–E per subject |
| Best for | Well-rounded students, undecided majors | Students focused on specific subjects |
| Extras | Compulsory essay, theory & service | Optional EPQ for an extra qualification |
Which one should you choose?
Choose the IB Diploma if you want a broad, balanced education, enjoy writing and research, and haven't fixed on a single field. Choose A-Levels if you already know your direction (e.g. medicine, engineering) and want to go deep in a few subjects. Both are accepted by top universities; check your target degree's specific subject requirements.
Frequently Asked Questions
Is the IB harder than A-Levels?▾
The IB is broader and adds a compulsory core (essay, theory of knowledge, service), so the workload is wider; A-Levels go deeper in fewer subjects. 'Harder' depends on whether you prefer breadth or depth.
Do UK universities accept the IB?▾
Yes. UK universities publish IB entry requirements alongside A-Level ones and accept both for admission.
Which is better for medicine or engineering?▾
A-Levels let you focus deeply on the required sciences/maths, which some applicants prefer; the IB is equally accepted as long as you take the right Higher Level subjects.
