IB Math Analysis and Approaches: Complete Guide for SL and HL Students

• Advanced calculus
• Complex trigonometric functions
• Sequences and series
• Proofs and mathematical induction
• Differential equations
• More rigorous problem solving and abstraction

HL also includes additional hours of instruction and challenging past paper questions.

Assessment Structure

For SL:

• Paper 1 (Non-calculator): 90 minutes, 40% of final grade
• Paper 2 (Calculator): 90 minutes, 40% of final grade
• Internal Assessment (IA): 20% of final grade

For HL:

• Paper 1 (Non-calculator): 120 minutes, 30%
• Paper 2 (Calculator): 120 minutes, 30%
• Paper 3 (Extended Response, Calculator): 60 minutes, 20%
• IA: 20% of final grade

The Math AA Internal Assessment (IA)

The IA is a mathematical exploration (6–12 pages) where students investigate a math concept of their choice.

Examples:

• The mathematics of music scales
• Modeling disease spread
• Fractals in nature
• Predicting outcomes in game theory

Tips for success:

• Choose a topic that truly interests you
• Apply real-world data or simulations
• Use clear structure and correct notation
• Reflect on the limitations and scope of your model

How Is IB Math AA Graded?

Like all IB subjects, AA is graded from 1 to 7 based on performance in the final exams and the IA.

To do well:

• Review each topic thoroughly and cross-link concepts
• Clarify errors early and seek help on weak areas
• Use a graphic display calculator effectively (especially HL)

FAQs: IB Math Analysis and Approaches

Q1: What’s the main difference between AA and AI?
AA is more theoretical, focusing on algebra and calculus. AI is more applied, with emphasis on statistics and modeling.

Q2: Should I take AA HL or SL?
Take AA HL if you're confident in math and aiming for STEM degrees. Take AA SL if you want a strong math foundation without the intense depth.

Q3: Is IB Math AA accepted by universities?
Yes. Top universities (especially in STEM fields) often prefer or require AA HL for competitive programs.

Q4: Is the IA the same for AA and AI?
The structure is similar, but the math content and focus differ based on course type and level.

Q5: How long is the course?
AA SL: ~150 teaching hours.
AA HL: ~240 teaching hours.

Q6: Can I switch between AA and AI later?
It depends on your school’s policy and timing. It’s easiest early in Year 1.
