The GRE Quantitative Reasoning section tests math at roughly a high school level — but the format, the question types, and the time pressure are unlike anything you have seen in high school or college courses. Many test-takers find the GRE Quant section the most strategy-dependent of any standardized test. This guide breaks down what the GRE actually tests, the four unique question types you will encounter, the content areas to master, and the strategies that consistently produce 160+ scores.
The GRE General Test, as of the 2023 redesign, contains two Quantitative Reasoning sections. The second section is adaptive: it adjusts difficulty based on your first-section performance. The math content tests high-school-level material, but the questions are designed to test critical thinking rather than rote computation.
| Aspect | Details |
|---|---|
| Sections | 2 quant sections |
| Questions per Section | ~12 in section 1, ~15 in section 2 |
| Total Quant Time | ~47 minutes total |
| Calculator | On-screen calculator provided (limited) |
| Scoring | 130–170 scale |
| Adaptive | Yes — section 2 difficulty depends on section 1 performance |
GRE Quant questions are not algebraically harder than the SAT or ACT. What makes them tough is the unusual question formats — especially Quantitative Comparison. Mastering the question types is more important than mastering advanced math.
The hallmark GRE question type. You are given two quantities (Column A and Column B) and must decide whether A is greater, B is greater, they are equal, or the relationship cannot be determined from the information given. There are always exactly four answer choices.
Standard multiple choice with five answer options. One correct answer. These behave like SAT/ACT questions but cover slightly more advanced math.
You must select all correct answers from a list of three to eight options. No partial credit — you must get every correct option and not select any wrong ones. These are the highest-pressure questions on the test.
You type your numeric answer into a box. No multiple choice to back-solve from. These reward precision and rule out elimination strategies.
Integers, fractions, decimals, percentages, ratios, exponents, square roots, and number theory (factors, multiples, prime numbers, divisibility). The foundation of nearly every other section. Practice at fractions and exponents.
Linear and quadratic equations, inequalities, exponential expressions, functions, and word problems. Most of this is standard high-school algebra. Practice at algebra, linear equations, quadratics, and systems.
Lines, angles, triangles, quadrilaterals, circles, area, perimeter, volume, and the coordinate plane. Practice at geometry, Pythagorean theorem, and volume.
Statistics, probability, data interpretation from tables and graphs, and combinatorics (counting problems). Practice at mean/median/mode.
The unique format demands a unique approach:
Treat each option as a separate true/false question. Test each independently. Do not assume there is a specific number of correct answers — sometimes only one is correct, sometimes all of them are.
Without answer choices, accuracy matters more than ever. Double-check your arithmetic. Use the on-screen calculator when arithmetic gets complex. Pay attention to the form the answer should be in (integer, decimal, fraction).
Based on score reports analyzed over years, the topics that appear most often and where students lose the most points are:
Week 1: Diagnostic test. Identify question types you struggle with. Weeks 2–3: Drill Quantitative Comparison until the format feels natural. Weeks 4–5: Content review based on diagnostic weak areas. Week 6: Mixed practice problems daily. Week 7: Full-length timed practice tests (two). Week 8: Targeted review, light practice, sleep.
You do not need to find the actual values of both columns — only the relationship. Spending time computing exact values is often wasted.
The GRE loves to trick students who assume variables are positive integers. Always test x = 0, x = −1, and x = 1/2 in Quantitative Comparison problems.
The GRE calculator is limited but useful for tedious arithmetic. Practice with it during prep so you do not waste time learning the interface on test day.
If you find one correct answer and stop checking the others, you will miss any additional correct options and lose all credit. Always evaluate every option independently.
DeltaMath Practice covers most of the GRE Quant content with interactive problems. Focus your practice on:
Set difficulty to Hard for GRE-level rigor. For Quantitative Comparison and Multi-Answer practice, you will need official GRE materials (ETS publishes free practice tests and the Official Guide).
The scale is 130–170. A score of 155 is the 60th percentile. 160 is the 75th percentile. 165 is the 90th. Engineering and STEM PhD programs typically want 165+. Top business schools often want 160+. Humanities programs are usually more lenient on Quant but still expect 150+.
Both are accepted at many graduate schools. The GMAT is required at many business schools but increasingly accepts GRE scores. GRE Quant covers a wider range of basic math but is generally considered slightly easier than GMAT Quant. The GMAT has a unique Data Sufficiency question type that has no equivalent on the GRE. Check your target programs to confirm which is accepted.
Yes — you can retake the GRE once every 21 days, up to five times in any 12-month period. Most students take it once or twice. ETS offers a ScoreSelect option that lets you choose which test scores to send to schools, so a bad day will not haunt your application.
Most successful test-takers spend 6 to 12 weeks of consistent prep. STEM students who use math daily can often prep in 4 to 6 weeks; humanities students who have not done math in years usually need 12 weeks or more. Quality of practice matters far more than total hours.
No. The GRE provides almost no formula reference, but the content is high school level. Memorize the basic geometry formulas (areas, volumes, Pythagorean), the quadratic formula, exponent rules, and basic statistics formulas. That covers about 95% of what you will need. The rest is logical application.
The GRE is section-adaptive, not question-adaptive. Your performance on section 1 determines whether section 2 is easy, medium, or hard. Within a single section, you can navigate freely and change answers. This makes the first section critically important.
