Key examiner messages
Top priorities from the principal examiner before you revise
The 2022 OCR AS Level Computer Science series (comprising H046/01 Computing Principles and H046/02 Algorithms and Problem Solving) represents a highly balanced sifting of foundational computer science knowledge.
With a total of 140 marks split equally across both 75-minute papers, candidates were assessed on their technical precision, coding aptitude, and descriptive maturity.
The overall difficulty is rated as 3 out of 5 stars.
While the mathematical components (binary arithmetic, Karnaugh maps) were relatively accessible, the demanding 9-mark essay questions and rigorous pseudocode tasks served as key differentiators for the top grades.

Command word playbook
How to match each command word to the expected response style
Match the expected response style for “State” questions.
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 “Write” questions.
Show formula, substitution, and unit; method marks need visible working.
Name or point to the specific feature asked for — avoid extra explanation.
Match the expected response style for “Complete” questions.
Identify similarities and differences explicitly — paired sentences or a table helps.
