Key examiner messages
Top priorities from the principal examiner before you revise
The June 2024 papers represented a high-standard AQA assessment.
Paper 1 demanded robust programming logic, particularly in Section D where students had to implement a CountdownCell subclass and a complex array-shifting algorithm (O(N)O(N)O(N) row shifting).
Paper 2, while containing highly accessible binary and logic gate questions, had extremely demanding extended-writing questions covering magnetic media, the TCP/IP stack, and medical AI ethics.

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.
Match the expected response style for “State” questions.
Show formula, substitution, and unit; method marks need visible working.
Match the expected response style for “Write” questions.
Present multiple perspectives with evidence; balance breadth and depth.
Match the expected response style for “Simplify” questions.
Match the expected response style for “Draw” questions.

Examiner notes & key calculations
- Off-by-One and Indexing Errors: In Paper 1, Question 13.1 (Shift row left), many candidates suffered from indexing errors or lost the leftmost cell because they did not store it in a temporary variable before shifting.
- SQL Delimiters: In Paper 2, Question 8.2, marks were frequently lost for omitting quotation marks or hashes around the date string ("29/09/2024").
- Vague Definitions: In questions regarding the Halting Problem and Local vs. Class Attributes, candidates often used colloquial definitions (e.g., stating a local variable "only works in one place") instead of precise academic terminology concerning scope and lifetime.
Analysis is paraphrased for study purposes. Always verify against the official examiner report and mark scheme.
