That Blue Square Thing

AQA Computer Science GCSE

September 2020: This page is the for the 2022 exam version of the AQA Computer Science GCSE course. This is for Year 10 teaching in September 2020.
These pages were copied over from the old syllabus and will get updated as I work through the new one. That means they won't always be totally up to date and I might miss something - check the updated date at the bottom of the page.
