Welcome to mrfraser.org

This site is designed primarily for students of computer science, providing FREE access to notes, presentations, links, code examples and other resources for IGCSE, GCSE, A–Level and IB Computing. There are a few resources aimed at KS1, KS2 & KS3, but not many, I’m afraid. The site is continually growing and evolving, albeit at an irregular rate as other commitments usually take precedence! I am currently developing resources for the new IGCSE (CIE) specification (9-1), which are being added when I have the time... If there are any resources missing that you think should appear here, or you think that resources are outdated or in need of an upgrade, please feel free to send some of your own!
