Both IB maths courses are rigorous and both exist at SL and HL. The real differences are style and what your future degree requires.
Analysis and Approaches (AA)
- Algebra, functions, proof and calculus with a strong focus on abstract reasoning.
- Includes a non-calculator paper.
- Best for maths, physics, engineering, computer science and economics degrees that ask for “HL Maths AA”.
Applications and Interpretation (AI)
- Statistics, modelling, financial maths and real-world problems, with heavy use of technology (GDC).
- Fits social sciences, business, psychology, biology, medicine (check requirements), design and many humanities.
- HL AI is demanding too: it includes matrices, differential equations, graph theory and advanced statistics.
How to decide
- Check the entry requirements of the degrees and universities you're considering. Many STEM courses specify HL AA.
- Think about how you like to work: proofs and algebra (AA) or modelling and data (AI).
- Talk to your teacher about your current algebra level: AA moves faster with symbolic manipulation.
Whichever you choose, our Maths AA notes and Maths AI notes follow the current guides topic by topic.
