That Blue Square Thing

Computer Science GCSE

Note: this page deals with the old Edexcel GCSE (grades A-G) which no longer exists. I'm keeping it as an archive and because a number of the resources will still apply to newer (grades 1-9) courses. The AQA GCSE CompSci pages deal with a current course.

These pages deal with the old Edexcel GCSE in Computer Science - which had its last exam in 2017. Some of the stuff here is still useful for me so I'll keep it up for a while at least.

Basics - algorithms and data:

A few core resources that don't belong anywhere else just now.

PDF iconAlgorithms - PDF of a powerpoint used in class

PDF iconInput, Process, Output model - a diagram

Errors and testing:

This relates to programming but will also appear in exams by itself.

PDF iconErrors - three types of error

PDF iconTesting - an introduction
