I sat the CHUF exam September last year as my first CPL exam. I was so nervous about the CPL exams that I spent about 8 weeks studying this as my first subject and I wanted a good mark. I was shocked when I sat the exam, hardly any of the practice exam questions from the Bob Tait book were even remotely similar to the Cyber Exam. In the end I passed (one more question wrong would have been a fail!) but I was feeling as if I had been studying the wrong material. I got home after the exam and checked the Bob Tait website for my versions currency and it seems my version was replaced the same month I bought it - Jan 08. The comment on the Bob Tait website said something like "this latest version completely rewritten for the CASA Cyber Exams". All my other CPL exams have been no problem with Bob Tait Texts. I did however ditch the two other out dated books I had and purchased the latest version to make sure this didn't happen again!
