The dvd is in several parts:
1. A series of chapters, introducing the techniques you're expected to use when taking the test.
Since these are exactly what you do when driving/riding, this is unnecessary for anyone with any experience at all on the roads. Having said that, the information was well-presented. There are no tips on how to pass the HP test - the DSA are sticking to their story that all you need is to have good real life hazard perception skills. Excuse me while I die laughing.
2. The HP test simulator.
This is the part I bought this massively overpriced dvd for. The simulator mimics the test very well, and the walk-through after each clip is also good. It makes a big difference to be given your score after each clip, as you begin to get a feel of what would constitute a 3, for example. You only /begin/ to make progress however, since THERE ARE ONLY 10 CLIPS ON THIS DVD! This is nowhere near enough to really get to grips with the test. I would strongly advise against buying this full-price therefore - get it secondhand somehow or borrow a friend's, because you'll get about an hour's use out of it and that's it. I still don't feel prepared for the test. Very, very frustrating! Also, the flag that shows your response has been registered is noticeably slow to appear - which rather defeats the object of a timed response...
3. Some multiple-choice questions.
These are the kind of things you get in the first part of the theory test. However, there are only 20 or so (so next to useless for preparation for that part of the test) and the fact that you can't select more than one answer at a time on the multiple-answer questions is irritating.
Let me repeat - DO NOT BUY THIS DVD FULL-PRICE! For not even one full test's worth of clips and more of the same garbled and contradictory instructions you get when booking the test, it's a collosal waste of money.
