2 powerpoints that cover the OCR content for the 9-1 GCSE for computer science. Units condensed into smaller chunks to help students. Paper 1 - covers all 8 units from the component one section. Paper 2 - covers all 6 units from the component two section. I created and have been using with students for 2 years - students enjoy using them. Gives them a good start for making their own revision resources.
