Manhattan Prep’s 4th Edition GRE Strategy Guides have been redesigned with the student in mind. With updated content and new practice problems, they are the richest, most content-driven GRE materials on the market. ​Written by Manhattan Prep’s high-caliber GRE instructors, GRE Quantitative Comparisons & Data Interpretation is really two books in one, thoroughly covering two of the quantitative question types on the GRE. The Guide to Quantitative Comparisons provides you with a framework for understanding what Quantitative Comparisons questions test. Most importantly, it discusses time-saving strategies specific to the Quantitative Comparisons format so that you can know when to solve rigorously, when to estimate, and when to test numbers. The Guide to Data Interpretation presents an overview of the types of graphs students can expect to see on the GRE. 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.
