What is the GRE Quantitative Reasoning section?
The GRE Quantitative Reasoning section measures your ability to understand, interpret, and analyze quantitative information and to solve problems using mathematical models. Two scored Quantitative sections appear in every GRE General Test, each containing 27 questions to be completed in 47 minutes — approximately 1 minute and 44 seconds per question. The score scale runs from 130 to 170 in 1-point increments, and GRE Quant is section-adaptive: your performance on the first section determines the difficulty level of the second.
Unlike standardized tests that reach into calculus or trigonometry, GRE Quant does not test advanced mathematics. All content is at or below the high-school level — arithmetic, algebra, geometry, and basic statistics. The challenge comes from problem complexity, multi-step reasoning, and time pressure, not from obscure formulas. A reference sheet with basic geometry formulas is provided during the exam.
GRE Quant question formats
GRE Quantitative questions appear in four formats. Multiple Choice (one answer) is the most familiar — choose one of five options. Multiple Choice (select all that apply) requires choosing all correct answers; partial credit is not given. Numeric Entry presents a blank where you type the exact answer — no guessing. Quantitative Comparison gives two quantities (A and B) and asks which is larger, whether they are equal, or whether the relationship cannot be determined. QC questions make up approximately 38% of all Quant questions and are the highest-leverage question type to master.
The five GRE Quantitative Reasoning topics
Integers, primes, divisibility, GCD, LCM, remainders, fractions, decimals, percentages, ratios, exponents, roots, and absolute value. Accuracy here is non-negotiable — arithmetic errors cascade through every other topic.
Linear equations, quadratics (factoring, quadratic formula, Vieta's), systems of equations, inequalities, absolute value equations, functions, coordinate geometry, and exponent/log rules.
Lines and angles, triangles (Pythagorean theorem, 30-60-90, 45-45-90, similar triangles), circles, polygons, 3D solids (volume and surface area), and coordinate geometry (distance, midpoint, slope).
Mean, median, mode, range, standard deviation, normal distribution, percentiles, z-scores, frequency tables, data interpretation, and basic probability and counting.
Rate/time/distance, work and pipe problems, mixture problems, simple and compound interest, percent change, proportional reasoning, and age/consecutive-integer problems.

The most important GRE Quant strategies
On QC questions, your goal is to determine the relationship between A and B — not compute exact values. Simplify both sides by adding/subtracting the same quantity, or test smart cases (0, 1, −1, fractions). The answer 'cannot be determined' is correct only when you find two cases that give different relationships.
When solving equations involving absolute values, inequalities, or fractions, always verify that your solution satisfies the original equation. Squaring both sides, multiplying through denominators, and other simplifications can introduce extraneous solutions — a common trap on GRE problems.
GRE geometry figures may not be drawn to scale and often omit useful information. Draw your own diagram, label all given values, and mark what you need to find. Most geometry problems become straightforward once you have a labeled diagram. Key Pythagorean triples to memorize: 3-4-5, 5-12-13, 8-15-17.
If mean > median, the data is right-skewed (few very large values pull the mean up). If mean < median, data is left-skewed. For data interpretation questions, calculate the weighted mean rather than averaging percents directly — this is the single most common data analysis mistake on the GRE.
The most common word problem error is computing before understanding. Read the full problem, define your variable explicitly ('let x = Maria's age now'), write the equation, then solve. For rate problems: always use d = rt. For work problems: add rates (1/time_A + 1/time_B = 1/time_together).
At 1:44 per question, spending 4 minutes on a single hard question breaks your entire section. GRE lets you mark questions and return. Flag anything that takes more than 2 attempts, move on, and return with fresh eyes at the end. The points for an easy question you skip are exactly the same as for a hard one you spent 5 minutes on.
How this free GRE Quantitative practice test is structured
This free GRE Quantitative practice test contains 110 original questions across all five topics in proportions that reflect the actual GRE Quantitative Reasoning section. Each question has five answer choices with a full step-by-step solution that shows the reasoning process, not just the answer. Questions are shuffled each session and can be filtered by topic for targeted practice. Use the 60-minute timed mode to simulate GRE Quant pacing (approximately 1 minute 44 seconds per question across a 27-question section).
