1. IB DP Math AA vs Math AI: Which Subject Should You Choose?
The International Baccalaureate (IB) Diploma Programme offers two distinct mathematics routes at Standard Level (SL) and Higher Level (HL):
| Feature / Topic | Math AA (Analysis & Approaches) | Math AI (Applications & Interpretation) |
|---|---|---|
| Primary Focus | Abstract mathematics, calculus, algebraic rigor, and formal proofs. | Applied mathematics, statistics, mathematical modeling, and technology (GDC). |
| Calculator Usage | Paper 1 is Non-Calculator; Paper 2 requires GDC. | GDC is allowed on ALL papers (Paper 1, Paper 2, Paper 3). |
| Best For University Majors | Engineering, Physics, Pure Mathematics, Computer Science, Economics (HL). | Business, Humanities, Social Sciences, Biology, Psychology, Medicine. |
| Calculus Weightage | Very High (algebraic integration, differential equations, proof). | Moderate (focused on rates of change & practical modeling). |
2. How to Score 20/20 on Your IB Math Internal Assessment (IA)
The Math IA is an individual exploration worth 20% of your final IB Diploma grade. Assessment criteria breakdown:
Criterion A: Presentation (4 Marks)
Structure, organization, coherent writing, clear graphs, tables, and latex mathematical formatting.
Criterion B: Mathematical Communication (4 Marks)
Correct terminology, clear notation, variable definitions, and precise diagram labels.
Criterion C: Personal Engagement (3 Marks)
Personal interest, unique topic choice, independent thinking, and personal reflection on findings.
Criterion D: Reflection (3 Marks)
Critical evaluation of results, analysis of limitations, alternate approaches, and practical implications.
Criterion E: Use of Mathematics (6 Marks)
Appropriate level of math (SL/HL), deep mathematical understanding, accuracy, and thorough validation of results.
