Another suggestion, which may avoid some difficulties that have been highlighted:
Ring Wally (never met him but have heard he is one of the best) and ask for a sim slot asap. It won't cost you much and they should be able to fit you in for half a day without waiting 3-months for your course to start. A half day, will give you briefing, and prob about an hour and a half in two sessions on the sim.
You will then have an awful lot of info on the way they want you to do things so your subsequent home study won't be wasting your time going in the wrong direction.
Believe me, the time in the sim will not be wasted.
Good Luck, and let us know how you get on.
