I purchased this book as I believed it to be a College Prep Book, providing a basic review of all high school math--from decimals and fractions to algebra and geometry, etc.--including a multiple choice section and answer key. I was very disappointed to discover that this book only addresses principles of decimals, fractions and ratios.

Although this book does provide extensive concept explanations, in my opinion, it is far too wordy--and, at times, confusing--given the author's poor command of the English language. In addition, every question had a "solution" immediately listed thereunder (without even as much as a double space (!)), which I found to be highly distracting and difficult to "test." I would not recommend this book!
