Motion exam preparation

FInally finished studying the Motion book and now have to go over the questions to learn for the exam. There is so much to learn but it frustrates me how there is so much more to learn in the other programmes as well and I don't know it yet. I really want to know compressor, color, soundtrack pro and DVD studio pro as well. Would really help me get jobs. I'm supposed to be meeting a guy later to edit a wedding video though. Hope it works out. Could do with the money. Still trying to log and capture the footage from the music video as well. So want to get it edited-I'm looking forward to it.
