Overview: IB Mathematics – AA vs AI
| Aspect | Analysis & Approaches (AA) | Applications & Interpretation (AI) |
|---|---|---|
| Content Focus | Theoretical, abstract, algebra, calculus, formal proof | Practical, data, statistics, modeling, technology use |
| Best For | Mathematics, Engineering, Physics, Computer Science | Business, Social Sciences, Psychology, Economics, Arts |
| Calculator Use | Non-calc exam (Paper 1); GDC for other papers | GDC allowed for all exams & coursework |
| Difficulty | Rigorous; deep concept mastery, more proofs & calculus | Challenging in practice & modeling, less theory |
| University Recognition | Preferred for top STEM & quantitative degrees | Accepted for business, social science, some STEM |
| Exam Structure (HL) | 3 Written Papers (one non-calc), IA (Theory-heavy) | 3 Written Papers (GDC in all), IA (Real-world modeling) |
Which IB Mathematics Course Suits You: AA or AI?
- Choose AA if you love abstract math, proofs, algebra, and plan to study engineering, comp-sci, physics or apply at top STEM universities.
- Choose AI for real-world applications, modeling, data analysis, and if you plan for social sciences, business, psychology, or economics degrees.
- Both AA & AI have SL and HL levels, with HL offering more depth and complexity.
- Important: Many top-tier universities (MIT, Cambridge, Imperial, etc.) require AA HL for quantitative STEM programs. Always check program entry requirements!
Course Structure & Key Topics (2025)
Common Core Areas (Both AA & AI)
- Number & Algebra
- Functions
- Geometry & Trigonometry
- Statistics & Probability
- Calculus
AA Focus Topics
- Formal proof, deep calculus (differentiation, integration, series)
- Complex numbers, vectors, advanced algebra
- Abstract problem-solving, mathematical reasoning (induction, logical arguments)
AI Focus Topics
- Statistical testing, probability distributions, modeling
- Analysis of large datasets, financial math
- Applications of mathematics in real-life contexts (technology, social sciences)
Key Formula Examples
Depreciation Formula (AI):
\( FV = PV (1 - \frac{r}{100})^n \)
where FV = future value, PV = present value, r = depreciation rate (%), n = years
\( FV = PV (1 - \frac{r}{100})^n \)
where FV = future value, PV = present value, r = depreciation rate (%), n = years
Distance Formula (AA & AI):
\( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)
\( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)
Sine Rule (AA & AI):
\( \frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C} \)
\( \frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C} \)
Volume of a Sphere (AA & AI):
\( V = \frac{4}{3} \pi r^3 \)
\( V = \frac{4}{3} \pi r^3 \)
Student Experience & Outcomes
- AA HL: Reported as most rigorous; major STEM and maths careers. Real challenge, especially in calculus and abstract reasoning. Global averages for AA HL grades are typically lower due to difficulty, but it’s highly rewarded by universities.
- AI HL: Focus on applied, practical skills and statistical modeling. Seen as more accessible by many, but requires consistent effort and fluency with technology and interpretation.
- Switching Courses: It’s possible to switch between AA and AI in IB Year 1 (limited window), but you must catch up with adjusted syllabus and internal assessment plan.
Frequently Asked Questions (FAQs)
Is AA harder than AI?
AA is generally more challenging due to theoretical calculus and proofs. AI HL remains challenging for practical statistics and applied modeling.
Which degree/career does AA benefit most?
AA is vital for engineering, computer science, physics, and quantitative STEM degrees.
Which degree/career does AI benefit most?
AI helps in social sciences, business, psychology, economics, design, and life sciences.
Can I switch from AA to AI or vice versa?
Yes, especially early in IB Year 1. Check with your school and plan ahead. You’ll have to catch up on missed content and internal assessment adjustments.
Do both AA and AI include calculus?
Yes. AA offers deep theoretical calculus, while AI covers applied, practical calculus topics.
Expert Tips for IB Math Success
- Start reviewing problem sets and past papers early. Use subject-specific revision sites like RevisionTown Study Hub and RevisionDojo centers.
- Join study groups and get formula sheets for AA and AI practice.
- Ask your counselor or teacher which universities require AA HL for your intended course of study.
- Practice with calculators (GDC) and understand its features for AI papers.
- Build strong mathematical habits—weekly review, milestone tracking, reflection.
