Key examiner messages
Top priorities from the principal examiner before you revise
The Summer 2023 Cambridge IGCSE International Mathematics (0607) Extended papers represent a balanced assessment.
Paper 21 is a rigorous, non-calculator test that rewards fluent mental arithmetic and algebraic manipulation.
Paper 41 demands confident calculator usage, coordinate geometry integration, and solid trigonometric problem-solving.
Paper 61 presents the toughest challenge, focusing on highly unstructured investigations and multi-variable modeling.

Command word playbook
How to match each command word to the expected response style
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Solve” questions.
Match the expected response style for “Simplify” questions.
Match the expected response style for “Find” questions.
Match the expected response style for “Sketch” questions.
Match the expected response style for “Show” questions.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
