What people say...

“
”

I received your sample copy today and took the opportunity to show it [to my outgoing] A2 students.

They said they liked the Layout and use of colour – compatible with the other textbooks they like, and they quickly found the Edward Snowden and NSA sections and were very engaged in the opposing arguments on each.

I liked the use of pseudo-code.

The key strengths of the materials are in their simplicity - you have the content pupils need to know, simply, attractively presented and then a well designed worksheet to test it. The worksheets look excellent and very effective as a tool to cement the learning.
