A-Level or IB: which is right for you?
The short answer
A-Levels suit students who want to specialise in about three subjects in depth. The IB Diploma suits students who want breadth, with six subjects plus Theory of Knowledge, the Extended Essay and CAS. Both are well recognised by UK and international universities. The best choice depends on the student's strengths, interests and intended course.
Key points
- A-Levels: usually three subjects, graded A* to E, assessed mainly by final exams.
- IB Diploma: six subjects (three Higher Level, three Standard Level) plus TOK, the Extended Essay and CAS, scored out of 45.
- Both are widely accepted by UK and international universities.
- The IB keeps more doors open; A-Levels allow deeper specialisation.
How A-Levels work
Students usually choose three subjects and study them for two years. Most A-Levels in England are linear, with exams at the end of Year 13, and are graded A* to E. Some include coursework or practical endorsements. The focus is depth: students can concentrate on the subjects most relevant to their degree.
How the IB Diploma works
Students take six subjects across languages, humanities, sciences, maths and the arts, three at Higher Level and three at Standard Level. Each subject is graded 1 to 7. The core adds Theory of Knowledge, a 4,000-word Extended Essay and Creativity, Activity, Service (CAS), which together contribute up to three points, giving a maximum of 45.

| Assessment | Mostly final exams | Exams plus internal assessments and the Extended Essay |

| Maths | Optional; Further Maths available | Compulsory, in Analysis and Approaches or Applications and Interpretation |
How universities see them
UK universities make offers in both systems, for example A*AA at A-Level or 38 to 40 points with specific Higher Level scores in the IB. International universities, including in the US and Europe, recognise both. Always check the specific course, because some ask for particular subjects or Higher Level grades.
How to decide
- Choose A-Levels if you know your direction and want to spend your time on the subjects you love.
- Choose the IB if you enjoy a wide range of subjects, are organised, and like extended independent projects.
- Consider workload: the IB asks for consistent effort across many subjects and deadlines.
Our A-Level tutors and IB tutors support students in both systems, including the IB Extended Essay and internal assessments.
