I do not have much of a mathematical background at all. I took a pre-college algebra class in college, and a statistics class, but that's all. What would be the best program for me to buy that would teach me all of the math concepts I need to know for the GMAT? I have the OG11, but that is basically all questions, and it assumes you know how to solve these problems already. I am considering buying the Nova GMAT Prep course, or possibly just buying math books covering basic algebra and geometry.
thanks a lot for any advice!
