Every GCSE Computer Science sheet published in August 2024, with answers. Systems, data representation, networks, algorithms and programming.
Every sheet in August 2024
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
- 1st August 2024A streaming company records which shows each user watches and uses this to recommend similar shows. Explain one ethical concern this could raise, even if the company only uses the data to improve recommendations.

- 3rd August 2024State the pseudocode operator commonly used to join (concatenate) two strings, then show how it joins 'Rev' and 'ision' to produce 'Revision'.
- 4th August 2024Give one example of an optical secondary storage device.
