This is excellent! It allows you to fully interact as if you were taking the test. It marks each category and identifies any trends, giving areas to focus on. The questions are worded well. It allows you to print the results to show your driving instructor.

The Hazard perception takes some getting used to, however, I am informed by my sister that it is like the real thing(she passed first time and used this to practice). The thing that you learn is not to be over cautious. For example, I was clicking the mouse every time I saw the slightest hazard. You can also loose points if you click for a hazard too soon or too late, so it gives you lots of practice for the real thing. You soon learn how the system works.
