Well, had my CSCS exam on Saturday. Passed. Think it's pretty scandalous that you have to pay £42.50 for this 'exam' but...
Anyway, bought another CD (Yep cirrus, from ebay, for a fiver. Well £4!)
and thought it was very useful.
Contains all the questions and answers that you'll be asked on the CSCS exam.
Generates random exams to practice with.
Provides a 'check and review' to see which questions you got wrong (if any).
Test yourself on seperate subjects if you're weak in a particular area (eg: handheld tools)
Basically, go on ebay and type in 'CSCS'.
Anyone going in for this exam, it's not difficult, really. However, £4 well spent on this CD in my opinion (£2CD £2p+p) if you feel you want to revise beforehand(which you should)
