IB Math AI HL Notes

Mathematics: Applications and Interpretation

Aimnova provides free IB Math AI HL revision notes aligned to the current syllabus, covering all five units plus the HL-only extensions — matrices and eigenvalues, graph theory, complex numbers, and further statistics and calculus including differential equations. Notes are structured by unit, topic and micro-topic so you revise in class order.

Math AI HL builds on the SL course with more advanced modelling and a dedicated Paper 3 — an extended problem-solving investigation that combines techniques across topics. A graphic display calculator (GDC) is expected throughout all three papers.

Work through the unit list below topic-by-topic, then reinforce with flashcards and exam-style practice in Exam Vault, focusing on where method marks are won and lost.

What's included

Unit-by-unit Math AI notes mapped to the IB syllabus
Exam-style worked examples focused on method + interpretation
Linked flashcards for spaced revision of key definitions and formulas
Exam Vault practice aligned to command terms and mark-scheme logic
SL and HL coverage with level toggle
Free to access — no account required for notes

How to use Math AI HL notes

1Start with a unit overview. Start with Unit 1 topics and build topic-by-topic confidence before jumping to mixed exam practice.
2Read micro-topic notes. Read one micro-topic at a time and focus on both the formula and the interpretation sentence.
3Test with flashcards. Use Math AI flashcards to keep formulas and command-term phrasing fresh.
4Practise exam questions. Practise in Exam Vault and check where method marks are lost before the final answer line.
