Key examiner messages
Top priorities from the principal examiner before you revise
The Summer 2024 AS Level series presented a moderate and accessible challenge.
While standard recall questions on cell biology and basic genetics offered easy scoring opportunities, the papers maintained GCE rigor through data-heavy evaluation questions and practical design tasks.
The distribution of marks across easy, medium, and hard bands was fair, ensuring a clear differentiation of top-performing students.

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 “contrast” questions.
Match the expected response style for “Deduce” questions.
Weigh arguments for and against with evidence; end with a supported judgement.

Examiner notes & key calculations
- Vague Practical Terminology: In the 6-mark experimental design questions (such as the amylase kinetic study), failing to specify the exact concentration, volume, or control variables (like temperature regulation via a water bath) limited students to lower mark bands.
- MathJax & Mathematical Accuracy: When calculating the percentage decrease of blood pressure through capillaries, many students failed to round to the requested two significant figures.
- Incomplete Comparisons: Writing lists of properties for one organelle or tissue without directly comparing it to the other is a common pitfall in comparative analysis prompts.
