mate, you will be fine...did mine a couple of weeks back. There is no easy, or hard about it - personally, I think its just down to how confident you are, and how well you adapt and get the feel for the bike and being on it. Even if it takes ages to get through the training, you will have to meet a certain expectation from the instructors before they sign you off and let you loose... As for the road part, and it being busy....all roads are busy these days, he wont let you out on the road until you have proven you can control the machine you are on - and even then, you will be on some little housing estate or something until you have mastered left and right turns, junctions etc... great feeling going out of that gate for the first time, even if it is with the instructor...what a rush.
