How to Study for IB Mathematics: Complete Strategy Guide | LearnByTeaching.ai
IB Mathematics — whether you take Analysis and Approaches (AA) or Applications and Interpretation (AI) — is structured around problem-solving, mathematical reasoning, and the effective use of technology across multiple exam papers. Success requires consistent practice with past papers, fluency with your graphing calculator, and the ability to show clear mathematical working that earns method marks even when your final answer is incorrect.
Exam Overview
Format
Two written papers (SL) or three papers (HL): Paper 1 (no calculator), Paper 2 (calculator allowed), Paper 3 (HL only — extended problem-solving); plus an Internal Assessment (mathematical exploration)
Duration
AA SL: 3 hours across papers; AA HL: 5 hours across papers; AI has similar structure
Scoring
1–7 scale; external papers are ~80% and the IA exploration is ~20%
Passing Score
4 is generally considered passing; STEM programs typically require AA HL with 6+ for full credit
| Section | Weight | Description |
|---|---|---|
| Paper 1 — No Calculator | 40% | Short and extended response questions testing algebraic manipulation, proof techniques, and conceptual understanding without technology |
| Paper 2 — Calculator Allowed | 40% | Short and extended response questions requiring graphing calculator (GDC) skills for modeling, statistics, and complex calculations |
| Paper 3 — Extended Problem Solving (HL only) | 20% | Two extended problems requiring investigation, conjecture, and proof, testing mathematical thinking at the highest level |
| Internal Assessment — Mathematical Exploration | 20% | A 6-12 page exploration of a mathematical topic of personal interest, assessed on communication, mathematical presentation, personal engagement, reflection, and use of mathematics |

Section Strategies
Paper 1 — No Calculator
40%
Paper 1 — No Calculator
40%Time Allocation
AA SL: 1 hour 30 minutes. AA HL: 2 hours. Allocate roughly 1.5 minutes per mark.
Key Topics
Study Approach
Paper 1 tests pure mathematical skill without technology. Focus on algebraic fluency — practice solving equations, simplifying expressions, and performing calculus by hand daily. Show every step of working clearly, as method marks are awarded generously.
Common Mistakes to Avoid
- ✗Not showing sufficient working for method marks
- ✗Algebraic errors in factoring or expanding
- ✗Forgetting exact trigonometric values (sin 30, cos 45, etc.)
- ✗Weak proof technique on AA HL questions
Paper 2 — Calculator Allowed
40%
Paper 2 — Calculator Allowed
40%Time Allocation
AA SL: 1 hour 30 minutes. AA HL: 2 hours. Use the first 5 minutes to scan all questions and plan your approach.
Key Topics
Study Approach
Master your GDC — know how to plot functions, find intersections, calculate statistics, solve equations, and perform regression analysis efficiently. Many Paper 2 questions are designed to be solved with calculator support, so using it effectively is as important as mathematical knowledge.
Common Mistakes to Avoid
- ✗Misusing the GDC (graphing calculator) and getting wrong results
- ✗Not writing down GDC steps or intermediate values
- ✗Rounding errors from premature rounding during multi-step calculations
- ✗Forgetting to set calculator to correct mode (degrees vs radians)
Paper 3 — Extended Problem Solving (HL only)
20%
Paper 3 — Extended Problem Solving (HL only)
20%Time Allocation
1 hour for two problems. Aim for 30 minutes per problem, but be flexible based on difficulty.
Key Topics
Study Approach
Paper 3 tests your ability to investigate, conjecture, and prove. Practice with past Paper 3s focusing on the progression from specific cases to general results. Read the entire problem before starting — understanding the overall direction helps you allocate time effectively.
Common Mistakes to Avoid
- ✗Not reading the entire problem before starting
- ✗Missing the pattern in numerical examples
- ✗Writing incomplete proofs that skip logical steps
- ✗Running out of time by spending too long on early parts
Internal Assessment — Mathematical Exploration
20%
Internal Assessment — Mathematical Exploration
20%Time Allocation
Allocate 2-3 months alongside regular coursework. Spend roughly 20-25 hours on research, writing, and revision.
Key Topics
Study Approach
Choose a topic that genuinely interests you and allows mathematics at an appropriate level. The best explorations use IB-level mathematics in an original context rather than attempting university-level mathematics poorly. Focus on clear communication, personal reflection, and mathematical rigor.
Common Mistakes to Avoid
- ✗Choosing a topic that is too simple or too ambitious
- ✗Presenting calculations without explanation or reflection
- ✗Poor mathematical notation and communication
- ✗Not demonstrating personal engagement with the topic

Test Day Tips
- 1
On Paper 1 (no calculator), if you get stuck on a question, move on and return to it later — the marks per question vary, and spending 15 minutes on a 3-mark question while skipping a 6-mark question is poor strategy.
- 2
Always show your working, even on Paper 2 with a calculator — writing 'from GDC' next to your answer is acceptable but including the setup (equation entered, window used) earns method marks if your answer is wrong.
- 3
Check that your calculator is in the correct angle mode (degrees or radians) at the start of Paper 2 — this is the single most common avoidable error on calculator papers.
- 4
For multi-part questions, use results from earlier parts even if you are not sure they are correct — marks are awarded for correct method applied to your previous answers.
- 5
Keep exact values (fractions, surds, pi) throughout calculations and only round at the final step — premature rounding causes cascading errors in multi-step problems.
- 6
Bring the formula booklet you used during practice so the layout is familiar — do not encounter it for the first time on exam day.
- 7
In the final 10 minutes, check every answer for units, correct notation, and reasonableness — a negative length or a probability greater than 1 indicates an error worth finding.
Pro Tips
Use Revision Village as your primary practice resource — it organizes every past paper question by topic and difficulty, so you can target your weak areas with precision rather than randomly working through full papers.
For Paper 1, practice 'speed drills' on basic algebraic manipulation (factoring, expanding, simplifying fractions) — the students who score 7 are not necessarily smarter but are significantly faster at routine steps, leaving more time for challenging questions.
Know your GDC inside out. Practice finding intersections, calculating standard deviation, performing regression, and solving equations so that each operation takes under 30 seconds — GDC fluency is worth 10-15 marks on Paper 2.
Teach a mathematical concept to someone by working through a problem step by step on a whiteboard. If you can explain why integration by parts works or how to set up a hypothesis test, you have internalized the method; if you stumble, that is your next study priority.
For the IA, choose a topic connected to a personal hobby or interest (sports statistics, music theory, architecture) — genuine curiosity produces better explorations than choosing a 'safe' topic, because personal engagement is explicitly assessed and examiners can tell the difference.
