GCSE Computer Science Worksheets
Choose from 19 GCSE Computer Science worksheet packs, covering 282 printable pages. This view is for finding a focused sheet to print: each PDF keeps one topic together and ends with its own full mark scheme.
How to use these worksheets
- Pick one skill that matches the lesson or the gap you have found. Open the pack page first if you want to check the level and length before using paper.
- Print the PDF and set a clear stopping point. A single focused GCSE Computer Science sheet usually gives better evidence than a long mixed booklet when you are checking whether one method is secure.
- Mark it with the scheme at the back. Keep the questions that were missed, write down the reason, then return to that skill with a new pack instead of repeating answers the student already knows.
See the method: Systems Architecture
A CPU has a clock speed of 2.5 GHz. Calculate the number of clock cycles it completes in 4 seconds.
- Convert GHz to Hz: 2.5 GHz = 2.5 x 10^9 Hz (cycles per second).
- Multiply the number of cycles per second by the time in seconds: 2.5 x 10^9 x 4.
- Calculate: 2.5 x 4 = 10, so the result is 10 x 10^9.
- Final answer: 1 x 10^10 clock cycles (10,000,000,000).
