I honestly get a headache everytime I read this book, you can use it for a quick reference if you have very advanced Excel skills. But, IT'S HORRIBLE AS A LEARNING TOOL..The book I'm mentioning below is a little more expensive but at lot easier to follow than the Excel books for half the price. A tip: search for Excel textbooks used to teach in college rather than those manuals at Barnes and Noble or your local bookstore, you will waste your money.New Perspectives on Microsoft Office Excel 2007, Comprehensive (Paperback)by June Jamrich Parsons , etc
