3. Assessment Breakdown

External Assessment (80%)

• Paper 1 (2 hours, 30%)
  • Non-calculator exam
  • Focuses on pure mathematics and proof-based questions
• Paper 2 (2 hours, 30%)
  • Calculator allowed
  • Tests applied math, modeling, and problem-solving
• Paper 3 (1 hour, 20%) – HL exclusive
  • Extended problem-solving in real-world contexts
  • Integrates multiple topics in one question

Internal Assessment (IA – 20%)

• Math Exploration Report (12–20 pages)
  • Students investigate a self-chosen mathematical topic

6. Essential Tools and Resources

Type	Recommended
Textbook	IB Mathematics HL by Oxford or Haese
Calculator	TI-Nspire CX CAS
Online Tools	Desmos Graphing Calculator
Competition Practice	AMC12 past papers

7. Common Challenges & Solutions

7.1 Difficulty Understanding Abstract Concepts

Solution: Use visual tools (e.g., GeoGebra) and animations to grasp limits, 3D geometry, etc.

7.2 Low Scores in Proof-Based Questions

Solution:

• Memorize standard proof formats
• Study examiner feedback samples
• Create a personal “Proof Bank”

7.3 Poor Time Management

Solution: Use segmented timing:

• MCQs: 90 sec/question
• Short answers: 5 mins/question
• Extended questions: 15 mins/question

8. University & Career Pathways

8.1 University Advantages

• Ivy League engineering and CS programs prefer Math HL
• UK G5 universities may offer credit exemptions for math-related majors

8.2 Career Prospects

• Quantitative Finance: Actuary, Risk Analyst
• Technology: Data Scientist, Algorithm Engineer
• Academia: Theoretical Mathematician

9. Study Timeline & Progress Planning

Phase	Key Tasks	Milestones
Semester 1	Build core understanding	Complete notes for 3 key topics
Semester 2	Start IA	Define research question and method
Semester 3	Mock exam practice	Score 6+ on 3 consecutive mocks
Final Prep	Address weak areas	Create error logbook (100+ Qs)

10. Habits of High-Scoring Students (7 Points)

Top achievers tend to:

• Apply flexible problem-solving methods
• Demonstrate original thought in IA
• Use graphing calculator functions effectively

Common Pitfalls to Avoid:

• Over-relying on memorized formulas
• Ignoring the importance of proof structure
• Choosing overly broad IA topics

Action Plan:

• Join a study group (3–5 peers ideal)
• Complete one full past paper per week
• Seek regular feedback from your teacher
