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.

Many thanks again for the resources, they are working very well and are proving invaluable.
