I booked my course with David about 3 weeks before the course started, he sends you out the training manual as soon as you book and I spent a couple of hours most days studying the material on the run up to the course. the training manual also contains all the question banks and the possible answers (it's multiple choice). It does not tell you which is the correct answer so you have to work through the material and work out the right answer. Then when the tests come around you have to see which of the questions come up and if you can remember the right answer!!
Hope this helps.
