Key examiner messages
Top priorities from the principal examiner before you revise
The Summer 2025 AS Biology (9700) series presented a classic mix of straightforward theoretical checks and rigorous quantitative reasoning.
Paper 11 maintained its usual discriminating standard, with multiple-choice options engineered to penalize shallow memorization.
Paper 21 served as the major conceptual test, introducing tricky biochemically active pathways (such as Vibrio parahaemolyticus enzyme VpSP37 kinetics and T-vec melanoma treatments).
Meanwhile, Paper 31 demanded high precision in graphical formatting and structural biological drawings.

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.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “State” questions.
Apply knowledge to an unfamiliar context; concise, practical points score best.
Match the expected response style for “Outline” questions.
