How Are the IB Maths Exam Papers Structured?

Both Mathematics AA and AI split into Paper 1 (no calculator), Paper 2 (calculator), and — for HL only — Paper 3, a longer problem-solving paper. SL sits two 90-minute papers worth 40% each; HL sits two 120-minute papers plus a 60-minute Paper 3, weighted 30/30/20. The IA makes up the remaining 20% at both levels.

Paper 1 tests pure mathematical reasoning without a calculator — expect algebraic manipulation and proof-style working. Paper 2 allows a graphic display calculator and leans on modelling, statistics and technology-based questions. Paper 3 (HL only) is two extended, unfamiliar-context problems worth 55 marks, rewarding sustained problem-solving over quick recall.

No — Paper 1 is calculator-free for both SL and HL, testing whether you can handle algebra and functions by hand. Paper 2 and Paper 3 both require an approved graphic display calculator (GDC). The IB publishes an approved GDC list each session, and using an unapproved model can genuinely cost you marks.

SL Paper 1 and Paper 2 each run 90 minutes for 80 marks. HL Paper 1 and Paper 2 each run 120 minutes for 110 marks, and HL Paper 3 adds 60 minutes for 55 marks. Total exam time is 3 hours at SL and 5 hours at HL.

No single paper is locked to one topic — any of the five syllabus topics (Number & Algebra, Functions, Geometry & Trigonometry, Statistics & Probability, Calculus) can appear on any paper. Paper 3, though, always draws two connected extended problems that often blend two or three topics into one investigation-style question.

Yes — Paper 3 exists only for Higher Level students in both Maths AA and Maths AI; SL candidates never sit it. It's worth 20% of the final HL grade and consists of two compulsory extended-response questions, each building through several sub-parts toward an unfamiliar or exploratory result.

In my experience marking mocks, most students find Paper 1 harder because there's no calculator to fall back on for arithmetic slips or checking a graph — a small early error compounds fast. Paper 2 feels more accessible since technology handles the heavy computation, but time pressure catches students who over-rely on the GDC.

Grade boundaries shift slightly each session, but as a rough guide a Level 7 in Maths AA HL often needs somewhere around 75-80% of total marks, with AI boundaries sometimes sitting a touch lower given its more applied focus. Always check the exact boundaries published with your results — they aren't fixed year to year.

Maths AA is generally more abstract and proof-heavy, especially at HL where calculus and algebraic rigour dominate. Maths AI leans on statistics, modelling and technology, which some students find more intuitive but no less demanding. Neither is objectively easier — the right choice depends on your strengths, not on chasing an easier grade.

Treat Paper 3 like a mini investigation, not a set of recall questions — work specifically through past papers from the current syllabus, since this paper's style has only existed since first exams in 2021. Practise building an answer step-by-step, because each sub-part usually feeds the next one.

Hugely — but only if you review them properly. Working through past papers under timed conditions shows you the command terms examiners actually use — "show that", "hence", "justify" — and where mark schemes reward method over a bare final answer. On RevisionPrep, topic-organised practice questions let you drill weak areas before attempting full timed papers.

The most common mistake I see is trusting the GDC's output without checking it makes sense — entering a function wrong and never noticing the graph looks impossible. Quick tip: always sanity-check a calculator answer against a rough sketch or estimate before writing it down; examiners can't award marks for a plausible-looking wrong number.

No — the exam structure (Paper 1, Paper 2, and HL's Paper 3) is identical whether your child takes Maths AA or Maths AI; only the content differs. AA suits students likely to pursue engineering, physics or pure maths at university; AI suits those heading toward economics, biology or business-related degrees.

Yes — the Internal Assessment, a single mathematical exploration, counts for 20% of the final grade at both SL and HL, the same weighting as HL's Paper 3. A weak IA can pull down an otherwise strong exam performance, so it deserves as much planning time as any single written paper.
