I work roughly 20/7. Yes I have all the books I need. I'm going for my third class, still have them all to do. I went and did my math exam, and did horribly on it. I thought I had done enough studying for it, but obviously not. The math was mostly algebra, and I studied it, but didn't study enough. I focussed more on geometry and trigonometry, which there was only one question on that. One other question was on area of a tank. I didn't think they would ask a question an a tank that had so many different sides. I remember seeing the formula in my head, but when I was studying, I thought, naw they won't ask that. So I have to take the math exam again in 5 months because I did so horribly bad. I think too much and usually don't answer the question correctly.
