Key examiner messages
Top priorities from the principal examiner before you revise
The June 2025 series of Oxford AQA International Biology (9610) maintained a balanced yet challenging profile, earning a solid 4-star difficulty rating.
Unit 1 tested foundation concepts with high analytical demands, Unit 2 merged physiological mechanisms with infectious diseases and host interactions, and Unit 3 demanded sophisticated ecological and genetics-based problem-solving.
A notable characteristic of this series was the heavy integration of practical assessment skills, particularly statistical interpretation (Spearman Rank), experimental design refinement, and data representation.

Command word playbook
How to match each command word to the expected response style
State features in sequence or list observable properties — do not explain causes unless asked.
Give reasons and link mechanism to outcome; each point needs a because/so chain.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Show formula, substitution, and unit; method marks need visible working.
Weigh arguments for and against with evidence; end with a supported judgement.
