The shorter GRE is section-level adaptive: your performance on the first section of Verbal (and of Quant) decides whether the second section of that measure is easier or harder.
- Analytical Writing — Analyze an Issue1 essay task · 30 minutes. Build and support your own position on an issue of general interest.
- Verbal Reasoning — Section 1About 12 questions · ~18 minutes. Reading Comprehension, Text Completion, and Sentence Equivalence.
- Verbal Reasoning — Section 2 (adaptive)About 15 questions · ~23 minutes. Its difficulty depends on how you did in Verbal Section 1.

- Quantitative Reasoning — Section 2 (adaptive)About 15 questions · ~26 minutes. Its difficulty depends on your first Quant section.
About 1 hour and 58 minutes of testing with no scheduled breaks. Verbal Reasoning has 27 scored questions and Quantitative Reasoning has 27, each split across two sections.
Because the test is , your work on the first section of each measure decides how hard — and how high-scoring — the second section can be.[2] Verbal and Quant carry equal weight on the question side (27 scored questions each), so split your study time between them, while keeping a focused block for the single essay:
The three scores are reported separately — there is no combined total.[6] This guide teaches all three measures — Verbal Reasoning first, then Quantitative Reasoning, then Analytical Writing.
1 · Verbal Reasoning
27 scored questions across two sections, about 41 minutes. Verbal Reasoning tests how well you read and reason: understanding passages, completing sentences with the right words, and using vocabulary in context. It rewards careful reading, not memorized definitions.[3]
Verbal rewards vocabulary in context and careful reasoning — not memorized definitions. Read for how a word works in the sentence around it.
Reading Comprehension
questions are based on passages of one or more paragraphs and come in three formats: multiple-choice with one answer, multiple-choice where one or more answers can be correct, and select-in-passage (click the sentence that does a stated job). The correct answer is always supported by the passage — never by outside knowledge.
Text Completion
gives a short passage with one, two, or three blanks; you pick the best word for each from separate columns of choices. There is no partial credit — every blank must be right. Predict your own word for each blank before reading the choices, and let the blank you are surest of anchor the others.
Sentence Equivalence
gives one sentence with a single blank and six choices, and asks for the two words that complete it to produce sentences alike in meaning. The key insight: a word can fit the sentence perfectly and still be wrong if it has no near-synonym among the choices, because you need a matching pair.
| Strategy | What to do |
|---|---|
| Predict first | Decide the meaning the blank needs before reading any choice |
| Find the pair | Look for two choices that match your prediction and each other |
| Trap: lone fit | A perfect single word with no synonym partner cannot be the answer |
| Use signposts | Contrast and cause words tell you the blank's direction |
| Roots & affixes | Break unknown words apart (bene- good, mal- bad, -ous full of) |
Checkpoint · Module 1 · Verbal Reasoning
Question 1 of 10
How many distinct question types make up the GRE Verbal Reasoning measure, and what are they?
2 · Quantitative Reasoning
27 scored questions across two sections, about 47 minutes. Quantitative Reasoning covers four content areas — arithmetic, algebra, geometry, and data analysis — at roughly high-school level, with an on-screen calculator. The challenge is careful reasoning under time, not advanced math.[4]
Every area appears as four question formats: Quantitative Comparison, multiple-choice (one answer), multiple-choice (one or more answers), and Numeric Entry. An on-screen calculator is provided.
Arithmetic
Arithmetic covers properties of integers, fractions, ratios, , and . Percent change is the change divided by the original value, times 100, and the turn ugly expressions into quick simplifications.
Algebra
Algebra covers linear and quadratic equations, inequalities, functions, word problems, and coordinate geometry. In , the is rise over run and is the y-intercept. To solve a quadratic , factor it or use the quadratic formula .
Geometry
Geometry covers lines, angles, triangles, circles, area, and volume — with no proofs. Know the workhorses: area of a triangle , area of a circle , circumference , and the .
a² + b² = c²
sides 1 : 1 : √2
sides 1 : √3 : 2
Memorize the Pythagorean triples (3-4-5, 5-12-13) and the two special right triangles — they turn many GRE geometry questions into instant recall.
Memorize the — the 45-45-90 (sides ) and the 30-60-90 (sides ) — and the common Pythagorean triples 3-4-5 and 5-12-13. Note that GRE figures are not necessarily drawn to scale, so reason from the given values, not the picture.
Data Analysis
Data Analysis covers statistics, graphs and tables, counting, and basic . Know that the is sensitive to outliers while the resists them, and that a larger means more spread.
| Concept | What to remember |
|---|---|
| Mean | Sum of values ÷ number of values; pulled toward outliers |
| Median | Middle value when ordered; resists outliers |
| Standard deviation | How spread out data is; larger = more spread |
| Probability | Favorable outcomes ÷ total outcomes (0 to 1) |
| Complement | P(not A) = 1 − P(A); use it for 'at least one' problems |
Quantitative Comparison
is the GRE’s signature math format. You compare Quantity A and Quantity B, and the four answer choices are always the same: A is greater, B is greater, the two are equal, or the relationship cannot be determined.
Choice (D) is correct only when the answer can change with different allowed values. Test small, large, negative, and fraction cases before settling on (A), (B), or (C).
Checkpoint · Module 2 · Quantitative Reasoning
Question 1 of 10
Given that n is a positive integer, Quantity A is 2n and Quantity B is n squared. Which statement correctly describes the relationship?
3 · Analytical Writing
One essay, about 30 minutes, scored 0–6. The current GRE has a single task: you build and defend your own position on a claim of general interest. Depth of reasoning and clear organization matter far more than length.[5]
The Analyze an Issue Task
You are given a statement on a topic of general interest plus specific instructions (for example, “discuss the extent to which you agree or disagree, and explain your reasoning”). A strong response takes a clear stance, develops it with relevant reasons and concrete examples, acknowledges complexity, and stays organized in standard written English.
What Graders Reward
Each essay is scored by a trained human rater and an automated scoring engine; when they agree the score stands, and a second human resolves larger gaps.[5] The rubric rewards insightful, well-supported analysis and clear control of language — not a fixed paragraph count or vocabulary showmanship.
| Higher score (5–6) | Lower score (3–4) |
|---|---|
| Clear, insightful position | Vague or shifting position |
| Specific, relevant examples | Restates the prompt without support |
| Addresses complexity / counterargument | One-sided, ignores objections |
| Logical organization with transitions | Disconnected paragraphs |
| Controlled, varied sentences | Frequent errors that obscure meaning |
Checkpoint · Module 3 · Analytical Writing
Question 1 of 3
On the current GRE General Test, the Analytical Writing measure consists of a single "Analyze an Issue" task. On what numeric scale is this task scored?
How to Use This Study Guide
A study guide is a map, not the whole territory — use it alongside official ETS practice in the POWERPREP materials and our free tools. Because the GRE is section-level adaptive and timed, the goal is steady accuracy under a clock, so spaced, mixed practice beats one long cram. Build vocabulary a little every day; it pays off across all three Verbal question types.
The three scores are reported separately — there is no combined total and no overall pass or fail. Wrong answers never cost you points, so answer every question.

GRE Glossary
Quick definitions for the terms you’ll see most across the GRE General Test:
- Analytical Writing
- The GRE measure consisting of one 'Analyze an Issue' essay, scored 0–6 in half-point increments by a trained human rater and an automated scoring engine.
- Analyze an Issue
- The single Analytical Writing task on the current GRE: state and develop your own position on a given claim of general interest, with reasons and examples.
- Educational Testing Service (ETS)
- The nonprofit that creates and administers the GRE. ETS sets the test content, scoring, and registration rules.
- Exponent rules
- When multiplying like bases, add exponents (xᵐ · xⁿ = xᵐ⁺ⁿ); when dividing, subtract them; a power of a power multiplies them; a negative exponent is a reciprocal.
- GRE General Test
- The Graduate Record Examinations General Test — the admissions exam administered by ETS and accepted by thousands of graduate and business schools. It measures Verbal Reasoning, Quantitative Reasoning, and Analytical Writing.
- Mean
- The average of a data set: the sum of the values divided by how many there are. It is pulled toward outliers.
- Median
- The middle value of an ordered data set. Unlike the mean, it resists outliers.
- Numeric Entry
- A Quant format with no answer choices — you type the answer (an integer, a decimal, or a fraction) into a box.
- Percent change
- The change in a quantity divided by its original value, times 100. Always divide by the starting amount.
- Probability
- The number of favorable outcomes divided by the total number of equally likely outcomes, a value from 0 to 1.
- Pythagorean theorem
- For a right triangle with legs a and b and hypotenuse c, a² + b² = c².
- Quantitative Comparison
- A GRE-signature math question that asks whether Quantity A is greater, Quantity B is greater, the two are equal, or the relationship cannot be determined.
- Quantitative Reasoning
- The GRE measure that tests arithmetic, algebra, geometry, and data analysis with an on-screen calculator. Scored 130–170.
- Reading Comprehension
- Verbal questions based on a passage — multiple-choice (one answer), multiple-choice (one or more answers), and select-in-passage formats — testing what the text says and implies.
- ScoreSelect
- The GRE option that lets you choose which test scores to send to schools after you see your results.
- Section-level adaptive
- The GRE design in which your performance on the first section of a measure (Verbal or Quant) determines the difficulty of that measure's second section.
- Sentence Equivalence
- A Verbal question type with one blank and six choices, asking for the two words that complete the sentence to produce sentences alike in meaning.
- Shorter GRE
- The current GRE General Test, introduced in 2023, which runs about 1 hour 58 minutes with no analytical-writing 'Analyze an Argument' task and no scheduled breaks.
- Slope
- The steepness of a line: the change in y divided by the change in x (rise over run). In y = mx + b, the slope is m.
- Slope-intercept form
- The linear equation y = mx + b, where m is the slope and b is the y-intercept (where the line crosses the y-axis).
- Special right triangles
- The 45-45-90 (sides 1 : 1 : √2) and 30-60-90 (sides 1 : √3 : 2) triangles, whose side ratios appear often on the GRE.
- Standard deviation
- A measure of how spread out data is around its mean. A larger standard deviation means more spread.
- Text Completion
- A Verbal question type that asks you to fill one, two, or three blanks in a short passage with the best word for each. No partial credit — every blank must be correct.
- Verbal Reasoning
- The GRE measure that tests reading comprehension, vocabulary in context, and reasoning, through Reading Comprehension, Text Completion, and Sentence Equivalence questions. Scored 130–170.

GRE Study Guide FAQ
The current GRE General Test has three measures: Analytical Writing (one 'Analyze an Issue' essay), Verbal Reasoning (27 questions across two sections), and Quantitative Reasoning (27 questions across two sections). Verbal tests reading and vocabulary; Quant tests arithmetic, algebra, geometry, and data analysis.
The current shorter GRE takes about 1 hour and 58 minutes total — roughly 30 minutes for the Analytical Writing essay, about 41 minutes for the two Verbal sections, and about 47 minutes for the two Quantitative sections. There are no scheduled breaks in the shorter test.
Verbal Reasoning and Quantitative Reasoning are each scored 130 to 170 in one-point increments, and Analytical Writing is scored 0 to 6 in half-point increments. The three scores are reported separately, there is no overall pass or fail, and wrong answers are not penalized — so answer every question.
There is no pass or fail; a 'good' GRE score is one that meets the expectations of your target programs. Competitive programs often look for Verbal and Quant scores in the 160s and an Analytical Writing score of 4.5 or higher, but requirements vary widely by field and school.
The GRE is section-level adaptive: within Verbal and within Quant, your performance on the first section determines whether the second section of that measure is easier or harder. You can still move freely among questions inside a section, flag items, and change answers before time runs out.
GRE Quantitative Reasoning covers arithmetic (integers, fractions, percents, exponents), algebra (equations, inequalities, functions, coordinate geometry), geometry (lines, angles, triangles, circles, area, volume — no proofs), and data analysis (statistics, graphs, counting, probability). The content is about high-school level, and an on-screen calculator is provided.
Work through the three measures in order — Verbal Reasoning, then Quantitative Reasoning, then Analytical Writing. After each module, take the checkpoint quiz to find gaps, drill that measure with our free practice questions and flashcards, and revisit flagged sections before test day.
