I liked the full coverage of everything available in one on this multi-disc DVD. There is plenty of hazard perception practise and exam tests to do. I only had a few minor issues with it mostly when I was playing the DVD on my laptop, through the XBox it seemed to work better. On some of the hazard perception practise exams it didn't always recognise my mouse clicks, it seemed to be related to particular clips as I let someone else have a go and they had the same problem. Also, in the practise theory questions it was a bit slow reacting to the answer I clicked which was a bit of a pain when you have to select multiple options. On the whole though for the price I thought it was a great DVD with everything you need included.
