What Is IB Mathematics?
The International Baccalaureate (IB) Mathematics curriculum includes two distinct course options—Mathematics: Analysis and Approaches (AA) and Mathematics: Applications and Interpretation (AI)—each available at Standard Level (SL) and Higher Level (HL). These courses are designed to suit varying learning preferences, academic strengths, and university goals.
Overview of the Two IB Math Courses
1. Mathematics: Analysis and Approaches (AA)
Key Focus:
- Abstract mathematical thinking
- Algebraic techniques
- Calculus
- Mathematical proofs
Who Should Choose AA:
- Students aiming for fields such as engineering, mathematics, computer science, or physics
Topics Covered:
- Number and Algebra
- Functions
- Geometry and Trigonometry
- Statistics and Probability
- Calculus
- HL includes: Proofs and Vectors
Assessment Structure:
- SL:
- Paper 1: No calculator
- Paper 2: Calculator allowed
- HL:
- Paper 1: No calculator
- Paper 2: Calculator allowed
- Paper 3: Extended problem-solving
Teaching Hours:
- SL: 150 hours
- HL: 240 hours
2. Mathematics: Applications and Interpretation (AI)
Key Focus:
- Data analysis
- Modeling
- Use of technology and statistical tools
Who Should Choose AI:
- Students interested in business, social sciences, economics, or life sciences
Topics Covered:
- Same five main topics as AA, but with emphasis on:
- Real-world modeling
- Statistics
- Use of calculators and technology
Assessment Structure:
- SL:
- Paper 1: Calculator allowed
- Paper 2: Calculator allowed
- HL:
- Paper 1: Calculator allowed
- Paper 2: Calculator allowed
- Paper 3: Extended modeling
Teaching Hours:
- SL: 150 hours
- HL: 240 hours
Comparison Summary: AA vs AI
Focus:
- AA: Theoretical math, abstract concepts, calculus, and proofs
- AI: Real-world application, data interpretation, modeling, and statistics
Best Suited For:
- AA: STEM majors (e.g., engineering, physics, math)
- AI: Business, social sciences, biology, and humanities
Calculator Use:
- AA: Some non-calculator assessments
- AI: Calculators permitted in all assessments
Assessment Papers:
- AA:
- SL: 2 papers
- HL: 3 papers
- AI:
- SL: 2 papers
- HL: 3 papers
Internal Assessment (IA):
- Required in both courses
- AA: Often focuses on proofs, abstract topics
- AI: Typically emphasizes real-world data modeling
How to Choose the Right IB Math Course
- Choose AA if you enjoy problem-solving, calculus, and logic.
- Choose AI if you're more comfortable working with data and real-life applications.
- Match your course to your university major or career goal:
- AA HL: Best for engineering, math, computer science, or physics
- AI SL/HL: Suited for economics, psychology, biology, and business
Internal Assessment (IA) Overview
Both AA and AI require an IA—known as the Math Exploration:
- It contributes 20% to your final grade.
- You choose a topic of personal interest and apply mathematical concepts.
- Encourages creativity and analytical thinking within your course’s focus area.

Frequently Asked Questions
1. Can I switch from AI to AA?
It’s possible early in the course, but difficult later due to differing foundations and expectations.
2. Which is easier: AA or AI?
Neither is easier—AA is abstract and proof-based, while AI is practical and application-driven.
3. Will universities accept both courses?
Yes. However, some STEM programs prefer AA HL. AI HL is acceptable for most other majors.
4. Are both courses equally rigorous?
Yes. They are designed to be equivalent in difficulty but different in focus.
5. Can I get a 7 in either course?
Absolutely. With consistent practice, use of resources like RevisionDojo, and understanding of course demands, a 7 is achievable.
