What people say...

Wow! This is certainly the most comprehensive and useful book out there for A Level OCR Computing.  I will be purchasing a class set for year 12 and 13.  

Craig Sargent. Head of Computer Science, Archway School

I'd just like to express my thanks for the material and support. If I had needed to have made my own resources, the results wouldn't have been as good and now I'm happy to tailor and tweak the resources to fit my own teaching and the student's own skills.
