GRE Quantitative Reasoning Section
Your comprehensive guide to the GRE math section — question types, topics tested, calculator policy, and proven strategies.
Understanding the GRE Math Section
The GRE Quantitative Reasoning section measures your ability to understand, interpret, and analyze quantitative information, solve problems using mathematical models, and apply basic mathematical skills and elementary mathematical concepts. The math content does not extend beyond what is typically covered in high school — but the way questions are constructed demands strong reasoning skills, not just computational ability.
You will encounter two Quantitative Reasoning sections on the GRE, each containing approximately 20 questions with 35 minutes allotted per section, for a total of roughly 40 questions across 70 minutes. The section is scored on a scale of 130 to 170 in one-point increments, with section-level adaptive difficulty determining the challenge level of your second section based on first-section performance.
The average Quantitative Reasoning score is approximately 153, which places you near the 57th percentile. STEM and quantitative programs often look for scores of 165 or above, while other programs may require more modest math scores. An on-screen calculator is provided for all Quantitative Reasoning questions.
The Four Types of Quantitative Questions
Each question type presents mathematical content in a distinct format. Familiarity with these formats is essential for efficient time management on test day.
Quantitative Comparison
These questions present two quantities — Quantity A and Quantity B — and ask you to determine the relationship between them. Your four answer choices are always the same: A is greater, B is greater, the two quantities are equal, or the relationship cannot be determined. These questions reward strategic thinking over computation. Often, you can determine the answer without actually calculating the values by using estimation, simplification, or logical reasoning.
Multiple Choice — Select One
Standard multiple-choice questions with five answer choices and exactly one correct answer. These are the most familiar question format and cover the full range of quantitative topics. While straightforward in structure, many of these questions are designed to test conceptual understanding rather than rote computation, so reading carefully and identifying exactly what is being asked is crucial.
Multiple Choice — Select One or More
These questions present a list of answer choices and ask you to select all that apply. There may be one correct answer, several, or all of them. No partial credit is awarded — you must identify every correct choice and no incorrect choices. These questions often involve understanding ranges, inequalities, or sets of values that satisfy given conditions, requiring systematic checking of each option.
Numeric Entry
Numeric Entry questions provide no answer choices at all. You must calculate the answer and type it into a box, either as an integer, a decimal, or a fraction. Without answer choices to guide you or use for estimation, these questions demand precise calculation and careful attention to what form the answer should take. They also test whether you can set up problems correctly from scratch.
Mathematical Topics Tested on the GRE
The GRE Quantitative section covers four broad content areas. While the math itself is at the high school level, questions are designed to test reasoning and problem-solving under time pressure.
Arithmetic
Properties of integers (divisibility, factorization, prime numbers, remainders), arithmetic operations, exponents and roots, estimation, percent, ratio, rate, absolute value, the number line, decimal representation, and sequences of numbers. Arithmetic concepts underpin many of the more complex questions on the test.
Algebra
Operations with exponents, factoring and simplifying algebraic expressions, relations and functions, equations and inequalities, solving linear and quadratic equations, solving simultaneous equations, setting up equations to solve word problems, and coordinate geometry including graphs of functions, equations, and inequalities, intercepts, and slopes of lines.
Geometry
Parallel and perpendicular lines, circles, triangles (including isosceles, equilateral, and 30-60-90 and 45-45-90 special right triangles), quadrilaterals, other polygons, congruent and similar figures, three-dimensional figures, area, perimeter, volume, the Pythagorean theorem, and angle measurement in degrees. Coordinate geometry is also included.
Data Analysis
Basic descriptive statistics (mean, median, mode, range, standard deviation, interquartile range, quartiles, percentiles), interpretation of data in tables and graphs (line graphs, bar graphs, circle graphs, boxplots, scatterplots, frequency distributions), elementary probability, conditional probability, random variables, probability distributions, counting methods (combinations, permutations), and Venn diagrams.
Calculator Policy and Data Interpretation Sets
On-Screen Calculator
An on-screen calculator is provided for the computer-based GRE. It performs basic arithmetic operations: addition, subtraction, multiplication, division, and square root. While having a calculator is helpful for certain computations, over-reliance on it can actually slow you down. Many GRE math questions are designed to be solved more efficiently through estimation, simplification, and strategic reasoning than through brute-force calculation.
Dr. Donnelly teaches students to recognize when the calculator is genuinely useful and when mental math or algebraic shortcuts will save valuable seconds. This skill alone can make the difference between finishing the section comfortably and running out of time.
Data Interpretation Sets
Some questions appear as part of Data Interpretation sets, where multiple questions are based on the same data presented in tables, graphs, or other data displays. These sets test your ability to extract relevant information from complex data presentations, perform calculations involving percentages and ratios, and draw conclusions supported by the data. Data Interpretation questions reward careful reading — pay close attention to axis labels, units, and footnotes before attempting calculations.
Proven Strategies for GRE Quantitative Success
Plug In Numbers
For questions with variables in the answer choices, substitute simple numbers for the variables and test each answer choice. This technique transforms abstract algebra problems into concrete arithmetic, dramatically reducing the chance of algebraic errors and often revealing the answer more quickly than solving symbolically.
Back-Solve from Answers
When a problem asks for a specific numerical answer and provides five choices, start by testing the middle value. If it is too large, eliminate it and the larger options; if too small, eliminate it and the smaller options. This systematic approach often finds the answer in just two or three attempts.
Estimate and Eliminate
Before diving into precise calculations, estimate the magnitude of the answer and immediately eliminate choices that are clearly too large or too small. On Quantitative Comparison questions, estimation is particularly powerful — you often need to know only which quantity is larger, not their exact values.
Private GRE Math Tutoring with Dr. Donnelly
Getting a strong score on the Quantitative Reasoning section can be particularly challenging for students who have been away from math for several years or who never felt confident with mathematical reasoning. Dr. Stuart Donnelly, Oxford Ph.D., has spent over 20 years helping students at every level — from those who need to rebuild fundamental skills to those pushing for 165+ scores — master the GRE math section.
Dr. Donnelly teaches the correct approach for each question type, emphasizing strategic problem-solving over brute-force computation. His students have achieved outstanding results, including scores at the 87th and 93rd percentiles, and have gained admission to top programs at Harvard, Georgetown, Columbia, NYU, and many others.
Private sessions are available online via Zoom or in person at our offices in New York City and San Diego. Dr. Donnelly will assess your current skill level, identify your specific areas of weakness, and build a targeted preparation plan designed to maximize your score improvement in the time available.
