Key examiner messages
Top priorities from the principal examiner before you revise
The May/June 2024 Biology 0610/43 Extended Theory paper represents a rigorous and structurally sound assessment of the Cambridge IGCSE syllabus.
While offering plenty of accessible recall questions to support a baseline score, it distinguishes itself with high-tariff, analytical questions that test deeper conceptual frameworks, especially in molecular genetics and ecological data interpretation.

Command word playbook
How to match each command word to the expected response style
Give reasons and link mechanism to outcome; each point needs a because/so chain.
State features in sequence or list observable properties — do not explain causes unless asked.
Match the expected response style for “State” questions.
Name or point to the specific feature asked for — avoid extra explanation.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Outline” questions.
Match the expected response style for “Predict” questions.
Apply knowledge to an unfamiliar context; concise, practical points score best.
