login to access resources

welcome to mrfraser.org

This site is designed primarily for students of computer science, providing notes, presentations, links, code examples and other resources for 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 AS/A Level (OCR) specification (first teaching Sept 2015), and the new GCSE (OCR) specification (first teaching Sept 2016), which are being added bit by bit. If there are any resources missing that you think should appear here, or you think that resources are outdated or in need of an upgrade, please feel free to send some of your own!
