This visually appealing knowledge organiser helps pupils revise the system security section of the GCSE in Computer Science. Written originally for OCR Computer Science (J276), it is also suitable for helping pupils revise for other exam boards.


One PDF document contains the knowledge organiser and the second PDF document includes tips of revision techniques allowing pupils to pick a technique they prefer. Once they have revised the topic, they can attempt the 8 mark exam practice question on the second sheet and mark it themselves using the mark scheme included.


This resource makes an ideal homework task, can be used as part of a lesson or given to pupils to help them with their exam revision.
