Short answer: In the IB Math AA vs AI choice, pick Math AA (Analysis and Approaches) if you’re aiming for maths-heavy degrees such as engineering, physics, computer science or maths, which often ask for AA HL. Pick Math AI (Applications and Interpretation) for business, social sciences, psychology, biology or design, where statistics and modelling matter more than algebra and proof.
Key takeaways
- Math AA focuses on algebra, calculus and proof; Math AI on statistics and modelling.
- Both courses are offered at SL (150 hours) and HL (240 hours).
- Both include the mathematical exploration, worth 20% of the final grade.
- Many maths-heavy university courses ask for AA HL; always check each course page.
- Revised AA and AI courses start in August 2027, with first exams in May 2029. Check the IBO website.
What is the difference between IB Math AA and AI?
In the International Baccalaureate (IB) Diploma Programme, Math AA builds algebra and calculus skills with and without technology, while Math AI centres on modelling and statistics, with technology throughout.
| Math AA (Analysis and Approaches) | Math AI (Applications and Interpretation) | |
|---|---|---|
| Focus | Algebra, functions, calculus, proof and abstract reasoning | Statistics, modelling, real-world data and technology |
| Style of questions | Manipulating expressions, deriving results, justifying steps | Interpreting data, building models, heavy use of the graphic display calculator (GDC) |
| Calculator use | Paper 1 is calculator-free | Technology required on every paper |
| Exams | SL: Papers 1 and 2 · HL: Papers 1, 2 and 3 | SL: Papers 1 and 2 · HL: Papers 1, 2 and 3 |
| Often suits | Engineering, physics, maths, computer science, economics at selective universities | Business, psychology, biology, geography, design |
| Teaching hours | SL 150 · HL 240 | SL 150 · HL 240 |
| Internal assessment | Mathematical exploration, 20% | Mathematical exploration, 20% |
Is Math AA harder than Math AI?
Math AA is not automatically harder than Math AI; the two courses are hard in different ways. AA is tough for students who struggle with algebra and multi-step reasoning; AI is tough for those who find wordy, real-world statistics questions difficult.
Does HL or SL maths matter for university?
Yes, the choice between HL and SL often matters more for university than AA vs AI. Many competitive courses in engineering, physics, maths, computer science and economics ask specifically for Math AA HL. Some accept AI HL, and many non-STEM courses only need SL in either.
Always check the exact subject requirements on each university’s admissions page before choosing. Requirements vary by university, course and country. Our guide to choosing the right IBDP subjects covers the wider picture.
Which IB Math course should I choose?
The right IB Math course depends on your intended degree, your algebra confidence and how you like to think.
Choose AA HL if:
- You’re considering engineering, physics, maths, computer science or economics at a selective university.
- You did well in Cambridge IGCSE Extended or Additional Mathematics and enjoy algebra.
- You like proving why something works, not just using it.
Choose AA SL if you’re comfortable with algebra but your degree doesn’t need HL maths.
Choose AI SL or HL if:
- Your interests lie in psychology, biology, social sciences, business or design.
- You enjoy working with real data and technology more than abstract algebra.
- Your target courses list AI as acceptable (check first).

Can I switch from AA to AI (or HL to SL) during the IB?
Switching IB Math course is often possible early in DP Year 1, but the rules are set by each school. Moving from HL to SL is usually easier than the reverse. Speak to your IB Coordinator early.
Is the IB Math syllabus changing in 2027?
Yes. The IB’s revised Math AA and Math AI courses start first teaching in August 2027, with first exams in May 2029. Students starting the Diploma before August 2027 stay on the current courses. Both courses keep SL and HL, with slightly fewer marks per paper.
Frequently asked questions
Which IB Math is better for medicine?
Either can work. Many medical schools accept Math AA or Math AI, often at SL, but requirements differ widely by university and country. Chemistry, and often Biology, usually matter more for medicine. Check each medical school’s admissions page before committing to a maths course.
Can I study engineering with Math AI?
Sometimes, but it limits your options. Some universities accept Math AI HL for engineering, while many engineering courses require Math AA HL. If engineering is a serious possibility, Math AA HL keeps the most doors open.
Is Math AI SL considered “easy maths”?
No. Math AI SL is the most accessible IB Math course, but it is still a rigorous qualification. Universities accept it for many courses that don’t require advanced maths, though courses that need strong maths usually ask for AA or HL.
Do both IB Math courses have an internal assessment?
Yes. Both Math AA and Math AI include the mathematical exploration, an investigation of a maths topic chosen by the student. It counts for 20% of the final grade at both SL and HL.
When should I get tuition for IB Math?
Ideally early in DP Year 1, especially if Cambridge IGCSE Maths felt challenging or you’re taking AA HL. Gaps in algebra and functions grow quickly in the IB, and fixing them before the first internal exams is far easier than in DP Year 2.
Conclusion
AA vs AI isn’t about which course is “better”. It’s about matching the course to how you think and where you want to go.
