The material itself is a good training resource, for those new to health and safety issues and for refresher courses. The lack of any installation instructions is a concern, particularly as the cd does not auto run and does need to be started and then the software found.
Don't be put off by this though.
The sessions are easy to work through, and rewarding in their own right. They enable you to take the exam with confidence, and should improve your knowledge of health and safety issues, as well as assisting you to pass first time.
