I'm no genius, stink at math, and knew nothing about flying 2 weeks before I took it. But I did buy the three guides that were at Barnes and Noble (cliff notes, ARCO, and another random one) and studied them for the 2 weeks. I got a 6/6/6, which is passing. It's not the most amazing score but good enough considering my background and amount of time I studied. I would suggest getting those study guides and practicing.
