IB Math Demystified: A Complete Guide to AA and AI for Students

Best for: Students interested in social sciences, business, biology, and subjects that involve statistical and applied thinking.

Who Should Choose IB Math AA?

• You excel in algebra and enjoy theoretical problem-solving.
• You're interested in STEM fields—like engineering or physics.
• You prefer working through logical, step-by-step calculations.
• You want a solid foundation in proof-based mathematics (especially at HL).

Who Should Choose IB Math AI?

• You enjoy real-life problem contexts like economics or environmental studies.
• You’re more comfortable using calculators and technology in math.
• You prefer interpreting data and building mathematical models.
• You're aiming for university studies in social sciences, business, or life sciences.

Common Features of IB Math Courses

Internal Assessment (IA) – The Math Exploration

Both AA and AI require students to complete an internal assessment—an exploration of a mathematical topic of personal interest. It encourages independent research and real-world application.

Use of Technology and Calculators

Calculators are:

• Optional or restricted in AA SL/HL (Paper 1: no calculator)
• Mandatory throughout in AI SL/HL (used in all papers)

IB Math SL vs HL: What’s the Difference?

Understanding the distinction between Standard Level (SL) and Higher Level (HL) in IB Math is essential for selecting the course that aligns with your academic goals and university plans.

• Teaching Hours:
  • SL: Approximately 150 teaching hours
  • HL: Approximately 240 teaching hours
• Paper 3 (Extended Assessment):
  • SL: Not included
  • HL: Included (required for HL students; focuses on extended problem-solving)
• Depth of Content:
  • SL: Covers the core syllabus only
  • HL: Includes core plus additional topics, such as proof and vectors (AA HL)
• Internal Assessment (IA) Weight:
  • SL: 20% of the final grade
  • HL: 20% of the final grade
• Best Suited For:
  • SL: Students aiming for general university prerequisites or humanities-related degrees
  • HL: Students targeting STEM-related programs, competitive science degrees, or mathematics-intensive fields

Detailed Comparison: AA vs AI

The two math pathways—Analysis & Approaches (AA) and Applications & Interpretation (AI)—serve different academic needs. Here’s a side-by-side breakdown of their curricular emphases:

Curriculum and Topics

• Algebra and Functions:
  • AA: Strong emphasis on symbolic manipulation, transformations, and abstract modeling
  • AI: Moderate emphasis with more focus on real-world function modeling
• Geometry and Trigonometry:
  • AA: Explored in-depth with theoretical and algebraic approaches
  • AI: Taught in context, focusing on geometry in applied scenarios
• Statistics and Probability:
  • AA: Limited coverage with theoretical framing
  • AI: Extensive use of statistics, data analysis, and probabilistic models in real-life applications
• Calculus:
  • AA: Deep and theoretical, covering derivations and symbolic manipulation
  • AI: Applied focus—interpreting graphs, rates of change, and optimization in practical contexts
• Proofs and Vectors (HL Only):
  • AA: Included in HL with an emphasis on abstract reasoning, vector operations, and formal proof
  • AI: Not included in HL; instead, more modeling and real-data projects are emphasized

Internal Assessment Scoring Criteria

• Presentation and structure
• Mathematical content and understanding
• Personal engagement
• Reflection and analysis

FAQs About IB Math

Q1: Can I switch from AI to AA mid-course?
It depends on your school’s policy and how far into the program you are. Speak to your IB coordinator early.

Q2: Which is harder, AA or AI?
AA HL is generally considered more abstract and demanding. AI HL focuses more on applications and modeling.

Q3: Which IB Math course is better for business?
AI SL or HL is better aligned with business, finance, and statistics-based university degrees.

Q4: Are both courses accepted by universities?
Yes, but competitive STEM programs often prefer AA HL. Always check university prerequisites.

Q5: What’s the passing score for IB Math?
You need at least a 4 out of 7 in IB Math to count toward the diploma, although many universities require higher.

Q6: Can I use a calculator in all exams?
No. In AA Paper 1, calculator use is prohibited. In AI, calculators are allowed on all papers.
