# GRE Quantitative Reasoning

The GRE has two scored Quantitative Reasoning sections, and the possibility of a third unscored "experimental or research" section (which may be Quantitative Reasoning or Verbal Reasoning), and provides a calculator to students in both the computer- and paper-based testing formats. Each Quantitative Reasoning section consists of approximately 8 Quantitative Comparisons, 9 Problem Solving items, and 3 Data Interpretation questions. Some questions are numeric entry, and some are multiple choice (with one or more answers). The test is intended to evaluate basic math skills, elementary math concepts, the ability to quantitatively reason and to model and solve problems with quantitative methods. Some problems are purely mathematical, some are posed as real-life problems, and some are "word problems" that must be interpreted and modeled mathematically.

Required skills to succed at GRE Quantitative Reasoning include Arithmatic, Geometry, and Data Analysis. Test content generally includes high school statistics and mathematics at a level no higher than Algebra 2. The test does not cover trigonometry, calculus, or higher-level math. The exam will use standard high school mathematics notation unless otherwise noted. Standard mathematical assumptions of the exam include that all numbers are real numbers, all figures lie in the plane of the computer or test paper, geometric figures are not necessarily drawn to scale (so you cannot assume that lengths and angles measure properly), coordinate systems are drawn to scale (so you can estimate or compare quantities if they are in an x/y grid or number line, for example), and graphical data presentations such as bar graphs or line graphs are drawn to scale. Some questions are independent, and others are part of a set of questions called a Data Interpretation Set, using the same data presented in tables or graphs or other displays.

The Quantitative Reasoning sections of the exam have four question types: Quantitative Comparison questions, Multiple Choice questions (select one answer), Multiple Choice questions (select one or more answers), and Numeric Entry questions. The test is adaptive between sections, so students who perform well on their first Quantitative Reasoning section will "level up" and face a more difficult second section.
