🧠 Examiner Tips to Get A★ in IGCSE Chemistry 2025

1. Learn the Mandatory Diagrams

• Electrolysis cell

• Fractional distillation column

• Titration setup

• Paper chromatography

• Blast furnace

These appear almost every year.

2. Perfect Your Calculation Skills

Common calculation topics:

• Empirical & molecular formula

• Titrations

• Moles ↔ Mass ↔ Concentration

• Percentage purity & yield

Students who practice calculations daily improve their Paper 4 score by 30–45%.

3. Use the “Reason + Result” Technique

IGCSE Chemistry marking schemes reward explanations, not statements.

Example:
“Magnesium is more reactive because it loses electrons more easily.”

4. Write According to Marking Scheme Language

Use phrases like:
✔ “More frequent successful collisions”
✔ “Ions are free to move”
✔ “Electrons delocalized”
✔ “Weak intermolecular forces”

These match CAIE expectations.

5. Memorize Common Chemical Tests
