It also discusses the different types of questions typically seen on the GRE and provides guidelines for reading graphs and combining information from different graphs to answer questions. Each chapter provides comprehensive coverage of the subject matter through rules, strategies, and in-depth examples to help you build confidence and content mastery. In addition, the guide contains "Check Your Skills" quizzes as you progress through the material, complete problem sets at the end of every chapter, and mixed drill sets at the end of the book to help you build accuracy and speed.
