GRE Quant: The 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 tests your math skills. It covers basic math concepts taught in high school — but the questions require strong reasoning, not just number crunching.
Here's what you need to know at a glance:
- Questions: 27 in total, in two sections (12 questions, then 15 questions)
- Time: 21 minutes for the first section and 26 minutes for the second (47 minutes total)
- Score range: 130–170 in one-point steps
- Average score: 157.6 (ETS, test takers July 2022–June 2025); a 160 is the 50th percentile and a perfect 170 is the 89th
- Calculator: On-screen calculator provided
- Adaptive: The first section is of average difficulty, and how you do on it sets the difficulty of the second
STEM, economics and business programs often look for Quant scores of 165 or higher, which is only the 67th percentile because Quant scores are so high overall. Other programs accept more modest scores. Either way, smart preparation makes a big difference. See the full GRE percentile table.
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
You see two quantities — A and B — and decide which is larger. The four answer choices are always the same:
- A is greater
- B is greater
- They are equal
- Cannot be determined
These reward smart thinking over computation. You can often find the answer without calculating exact values.
Multiple Choice — Select One
Five answer choices, one correct answer. This is the most familiar format. The questions cover all math topics on the GRE. Read carefully — many are designed to test understanding, not just computation.
Multiple Choice — Select One or More
Pick all correct answers from a list. There could be one, several, or all. No partial credit — you must get every choice right. These often involve ranges, inequalities, or checking which values meet a condition.
Numeric Entry
No answer choices. You calculate the answer and type it in — as a whole number, decimal, or fraction. Without choices to guide you, these demand precise setup and careful calculation.
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
Covers the building blocks: divisibility, prime numbers, exponents, roots, percent, ratio, rate, absolute value, and number sequences. These concepts show up in many of the harder questions too.
Algebra
Includes exponents, factoring, functions, linear and quadratic equations, inequalities, word problems, and coordinate geometry (slopes, intercepts, graphing).
Geometry
Lines, circles, triangles (including special right triangles), quadrilaterals, polygons, 3D figures, area, perimeter, volume, and the Pythagorean theorem. Know your formulas and how to apply them quickly.
Data Analysis
Statistics (mean, median, mode, standard deviation), reading tables and graphs, probability, combinations, permutations, and Venn diagrams. These questions reward careful reading of charts and data.
Calculator Policy and Data Interpretation Sets
On-Screen Calculator
The GRE provides a basic on-screen calculator (add, subtract, multiply, divide, square root). It helps with messy arithmetic — but don't rely on it too much. Many questions are faster to solve with estimation or shortcuts.
Dr. Donnelly teaches you when to use the calculator and when mental math saves time. This skill alone can be the difference between finishing comfortably and running out of time.
Data Interpretation Sets
Some questions come in sets, all based on the same table or graph. These test your ability to:
- Pull the right numbers from complex data displays
- Calculate percentages and ratios from charts
- Draw conclusions supported by the data
Tip: Always check axis labels, units, and footnotes before you start calculating.
Proven Strategies for GRE Quantitative Success
Plug In Numbers
See variables in the answer choices? Pick simple numbers, plug them in, and test each choice. This turns tricky algebra into easy arithmetic and cuts down on errors.
Back-Solve from Answers
Start with the middle answer choice and test it. Too big? Eliminate it and the larger options. Too small? Eliminate it and the smaller ones. You'll usually find the answer in two or three tries.
Estimate and Eliminate
Before calculating, estimate the answer and cross off choices that are obviously wrong. This works especially well on Quantitative Comparison questions, where you just need to know which quantity is bigger — not the exact values.
