The graphics are excellent which will help the students understand the links between different aspects of computer hardware. I particularly like the example answers which clearly illustrate where marks can be achieved. --Ms Penny Cox. Head of Computer Science, Francis Combe Academy

I was really impressed with the revision guide and have ordered a set for my Year 10's. I normally get CGP but I really like the layout for ClearRevise! --Adrienne Devonport. Head of Computer Science, Salford City Academy

2.0 out of 5 stars First edition has a bug in an example about bugs

H.S. · 21 February 2023

It is ironic and more crucially incredibly confusing to students to have a bug in an example (on page 53) about finding bugs. The sum initialisation is a bug but the less than is correct (due to the order of the increment of count and sum addition lines) so if you make the suggested change '<' to '<=' the program becomes incorrect.
