IGCSE Mathematics (Core/Extended) Explained in Depth｜Course Structure, Assessment, and Study Tips

What is IGCSE Mathematics (Core/Extended)?

IGCSE Mathematics is one of the core subjects offered by Cambridge Assessment International Education (CAIE) and is designed for students aged 14–16 worldwide. The subject is divided into Core and Extended levels, allowing students to choose the tier that best matches their ability and academic goals.

Exam Structure and Paper Format

Core Exam Structure:

• Paper 1 (Short-Answer): 1 hour, 40 marks, no calculator
• Paper 3 (Application): 2 hours, 96 marks, calculator allowed

Extended Exam Structure:

• Paper 2 (Short-Answer): 1 hour 30 minutes, 70 marks, no calculator
• Paper 4 (Application): 2 hours 30 minutes, 130 marks, calculator allowed

Both tiers assess across computation, problem-solving, reasoning, and data handling.

Study Strategies and Preparation Tips

Effective Study Techniques:

• Daily practice by topic (e.g., algebra, geometry, statistics)
• Keep an error log to track recurring mistakes
• Practice with past papers to master formats and timing
• Learn to use a scientific calculator (e.g., Casio fx-991EX) efficiently

Recommended Resources:

• Cambridge IGCSE Mathematics Core and Extended (official textbook)
• Physics & Maths Tutor (free question bank)
• CGP Revision Guide (clear notes + practice questions)
