Key examiner messages
Top priorities from the principal examiner before you revise
The 2024 OCR AS Level Computer Science examination (H046/01 and H046/02) maintains a robust standard.
It acts as a realistic bridge to A-Level material, blending high-mark analytical discussions with strict, practical programming challenges.
The difficulty is graded fairly across both papers, though candidates with weaker foundations in assembly instructions (LMC), JavaScript syntax, and algorithm efficiency evaluations would have found several milestones challenging.
This places the series at a solid 3.5 out of 5 stars in overall difficulty.

Command word playbook
How to match each command word to the expected response style
State features in sequence or list observable properties — do not explain causes unless asked.
Present multiple perspectives with evidence; balance breadth and depth.
Name or point to the specific feature asked for — avoid extra explanation.
Match the expected response style for “Write” questions.
Match the expected response style for “Complete” questions.
