Key examiner messages

Top priorities from the principal examiner before you revise

1

The May/June 2024 series of the 9618 syllabus presents a rigorous, standard-setting suite of assessments.

2

While Paper 13 (Theory Fundamentals) and Paper 33 (Advanced Theory) rely heavily on precise definitions and exact mark-scheme terminology, Papers 23 and 43 demand a highly fluent grasp of procedural logic, object-oriented programming (OOP), and linear data structures.

3

The overall difficulty is high-medium, providing an excellent differentiator for top-tier candidates who can bridge the gap between abstract computer science concepts and syntactical programming execution.

Command word playbook

How to match each command word to the expected response style

ExplainFrequency: 18

Give reasons and link mechanism to outcome; each point needs a because/so chain.

DescribeFrequency: 15

State features in sequence or list observable properties — do not explain causes unless asked.

WriteFrequency: 12

Match the expected response style for “Write” questions.

CalculateFrequency: 8

Show formula, substitution, and unit; method marks need visible working.

StateFrequency: 8

Match the expected response style for “State” questions.

IdentifyFrequency: 6

Name or point to the specific feature asked for — avoid extra explanation.
