Key examiner messages
Top priorities from the principal examiner before you revise
The January 2024 exam series across Units 1 to 5 presents a balanced yet highly rigorous assessment of the Oxford AQA International Biology specification.
With a difficulty index of 3.8 out of 5.0, the papers demanded high-level data analysis, precision in mathematical calculations, and strong synoptic linkages.
A-level candidates were tested not just on rote memorisation, but on their ability to apply core biological principles to unfamiliar scenarios—ranging from the physiology of diving dolphins to epigenetic modifications in ripening peppers.

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.
Show formula, substitution, and unit; method marks need visible working.
Weigh arguments for and against with evidence; end with a supported judgement.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Match the expected response style for “Draw” questions.
