IB Maths AA SL Paper 2: GDC, Proof and Statistics
Mathematics: GDC or by hand, decide first
Paper 2 requires the GDC, but the method marks are not in the calculator. Roots, intersections, definite integrals and normal probabilities go to the GDC; proofs, simplification and exact values stay handwritten. Give every numeric answer three significant figures with units, and check part A before starting part B, which builds on it.
How is IB Maths AA SL Paper 2 assessed, and what does each part carry?
Paper 1 (no technology): Compulsory short- and extended-response questions; 80 marks (SL 40%); Paper 2 (this paper, GDC required): Short-response Section A + extended-response Section B; 80 marks (SL 40%); Exploration (internal assessment): 15 recommended hours within the 150-hour course (20%)
Assessment at a glance (2027)
| Component | Content | Weighting | Duration |
|---|---|---|---|
| Paper 1 (no technology) | Compulsory short- and extended-response questions; 80 marks | SL 40% | 1.5 h |
| Paper 2 (this paper, GDC required) | Short-response Section A + extended-response Section B; 80 marks | SL 40% | 1.5 h |
| Exploration (internal assessment) | 15 recommended hours within the 150-hour course | 20% | during the course |
IB Maths AA SL Paper 2 drilling technique: decide first whether the question wants the GDC or algebra – roots, intersections, definite integrals, normal probabilities and inverse functions go to the GDC; proofs, simplification and exact values still need written steps. Give every numerical answer to three significant figures (one decimal place for angles) with units. Check Section A before moving on, because Section B builds on it.
What each paper is actually testing
| Paper | Drill focus | How marks are lost |
|---|---|---|
| Paper 1 (no technology) | tests hand manipulation and proof | The mode is left on RAD and the whole triangle answer is wrong. |
| Paper 2 (this paper, GDC required) | sketch or model first, then GDC and interpretation | Only the screen value is copied, no formula and no substitution, so the method marks go. |
| Exploration (internal assessment) | own topic, modelling and reflection | The exploration reports calculations but not the mathematics or the reflection, so it settles mid-band. |
What is each IB Maths AA SL Paper 2 paper really testing, and what should you drill?

Drill order: by topic, then by year, then the mark scheme
| Step | What you do | Why |
|---|---|---|
| 1. By topic | Work through each topic, starting with the paper that allows least help (no calculator / closed book) | Exposes what is genuinely not understood |
| 2. By year | Whole papers to time, one or two a week | Trains pace, stamina and question selection |
| 3. Mark scheme | Go through the marking scheme question by question and log the scoring steps you missed | Most lost marks are written wrong, not thought wrong |
Should drilling go by topic first or by year?
By topic first, then whole papers by year, then the mark scheme. The first third of the time goes topic by topic (8-10 years of the same topic back to back), the middle switches to timed whole papers, and the last fortnight only redoes the recurring errors from your log.
A 12-week drilling timetable
| Week | Phase | What to do |
|---|---|---|
| Weeks 1-3 | By topic: foundation | Topic by topic, starting with the easiest marks, building habits and recall |
| Weeks 4-6 | By topic: core | 8-10 years of the same topic back to back, errors classified by topic |
| Weeks 7-8 | By topic: advanced and electives | Elective and higher-order topics, now under time pressure |
| Weeks 9-10 | By year: timed papers | One full paper a week, timed, no reference materials |
| Week 11 | Mark scheme work | Question by question against the marking scheme; list the scoring steps you omitted |
| Week 12 | Plug holes and simulate | Only the recurring errors from your log, then one full exam simulation |
Subject-specific weighting for this timetable: Weeks 1-3: functions, equations, trigonometry. Formula first, then decide GDC or by hand.
Weeks 4-6: calculus and probability. Write the integral before evaluating; state mean and standard deviation before a normal probability.
Weeks 7-9: whole papers to time, thirty-five minutes for part A; finish each answer with three significant figures and units.
Weeks 10-12: the error log only, plus one rewrite of the exploration with its limits and reflection.
Use it properly: this is not a checklist to finish. Every week must keep time for redoing errors, or from week 9 you will be repeating the same batch.
Pacing
| Paper | Time | Suggested split |
|---|---|---|
| Paper 1 (no technology) | 1.5 h | analytic work: exact surds, fractions and algebra |
| Paper 2 (this paper, GDC required) | 1.5 h | about 40 min on Section A, 45 min on Section B, 5 min to check |
| Exploration (internal assessment) | during the course | work in stages, never in the last two weeks |
How should the time be split inside each IB Maths AA SL Paper 2 paper?
Paper 1 (no technology): analytic work: exact surds, fractions and algebra; Paper 2 (this paper, GDC required): about 40 min on Section A, 45 min on Section B, 5 min to check; Exploration (internal assessment): work in stages, never in the last two weeks
The drilling mistakes that cost the most marks
| Mistake | What it looks like | What actually happens | Instead |
|---|---|---|---|
| Trigonometry without DEG mode | Evaluating cos 52° straight away | A radian-mode GDC gives a completely wrong side length | Set DEG or RAD first, then enter the angle |
| Calculator answer only | Copying the screen output | All method marks are lost, keeping only the answer mark | Write the formula, the substitution and the integral |
| Too many decimal places | Roots written to five or six decimals | IB wants three significant figures, so marks are deducted | Give every answer to three significant figures |
| Total distance as a displacement | Writing s(2) − s(0) | The return leg cancels out and removes half the distance | Add the absolute values of each stage |
The error log and the mark scheme
Three columns: the question and the working as written, the scheme key words (formula, substitution, significant figures, units), and whether the loss was the mode, the method or the answer format. Format errors are the cheapest to fix – clear that column first.
How many years should you drill?
The current AA SL course was first assessed in 2019, and older Maths SL papers used different question shapes and calculator rules, so do not drill them wholesale. Three to five years of current papers set the shapes, then the official specimen covers the newer statistics and the exploration.
How many years of past papers is enough?
The current AA SL course was first assessed in 2019, and older Maths SL papers used different question shapes and calculator rules, so do not drill them wholesale. Three to five years of current papers set the shapes, then the official specimen covers the newer statistics and the exploration.
Frequently asked questions
Is this page a mock paper or a drilling guide?
This is the IB Maths AA SL Paper 2 drilling guide: assessment structure, drill order, a 12-week timetable, pacing, common mark losses and the error-log method. For questions with answers, use the IB Maths AA SL Paper 2 mock papers linked under Related.
By topic or by year first?
By topic. Eight to ten years of the same topic back to back is what exposes repeating errors; going straight to whole papers just repeats the same batch under time pressure.
How should the error log be written?
Do not copy out questions. Per error record four things: question reference, which step failed (concept, wording, calculation), what the mark scheme requires, and the correct action next time.
Can Paper 2 be done entirely on the GDC?
No. Roots, integrals and probabilities may use it, but the formula and the substitution must still be written, and proofs, simplification and exact values stay by hand.
How many significant figures?
Three, and one decimal place for angles, unless the question says otherwise. Do not round in the middle – round at the last step.

Next step: find a tutor / register as a tutor
After drilling, the hard part is telling a conceptual error from a writing error. Tell us the year group, the school and your available times, and TutorZone will match you with a tutor who knows the HKEAA assessment requirements.
Demand for tutors in this subject is steady, and those who can explain the marking scheme and where marks are won are especially sought after. Register free; you pay only when a match succeeds.
