Key examiner messages
Top priorities from the principal examiner before you revise
The January 2025 Oxford AQA International Biology (9610) series presents a robust, academically challenging set of papers across Units 1 to 5.
With a combined total of 375 marks spanning 450 minutes of examination, the suite tests both breadth of knowledge and deep clinical/practical application.
While standard recall questions on cell biology and anatomy offer accessible points, the papers increase in difficulty through multi-step mathematical calculations (such as Hardy-Weinberg estimations and blood loss equations) and demanding experimental evaluations requiring candidates to balance evidence 'for' and 'against' a given hypothesis.

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.
