Key examiner messages
Top priorities from the principal examiner before you revise
The Cambridge International AS & A Level Computer Science (9618) exam series for May/June 2024 maintains a high-quality standard, demanding rigorous practical execution alongside detailed theoretical foundations.
Across all four papers, we see a clear distribution of marks designed to separate grade boundaries, particularly focusing on string-trimming logic, custom binary tree traversals, and recursive implementation designs.

Command word playbook
How to match each command word to the expected response style
Match the expected response style for “Pseudocode” questions.
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.
Name or point to the specific feature asked for — avoid extra explanation.
Show formula, substitution, and unit; method marks need visible working.
