What the GRE measures and who takes it

The GRE (Graduate Record Examination) is a standardized test required by most graduate programs in the United States, Canada, and many other countries. It measures your ability to reason through verbal, quantitative, and analytical writing tasks — not your knowledge of specific subjects. Most people take it when they are explore to master's or doctoral programs, though some professional programs also require it.

The test is administered by the Educational Testing Service (ETS) and is offered year-round at testing centers and online. You can take it as many times as you want, though most test-takers prepare for one to three months before sitting for it. Your score is valid for five years from your test date.

Key Takeaways

  • The GRE has three sections — Verbal Reasoning, Quantitative Reasoning, and Analytical Writing — and takes about three hours and forty-five minutes to complete.
  • You can register and take the test online from home or at a testing center, and you choose which date and location work for you.
  • Most graduate programs have score ranges they expect, so check your target schools' websites before you register to know what score you are aiming for.
  • Official ETS prep materials and practice tests are more accurate predictors of your actual score than third-party prep books.
  • You do not need to memorize formulas or vocabulary lists — the test rewards reasoning and problem-solving over memorization.

The three sections and what they test

Verbal Reasoning has two sections of 20 questions each. You read passages and answer questions about what they say, find synonyms and antonyms, and complete sentences with missing words. The passages come from academic texts in science, history, social science, and the humanities. You have 30 minutes per section.

Quantitative Reasoning also has two sections of 20 questions each. You solve math problems involving algebra, geometry, statistics, and data interpretation. You do not need calculus or advanced math — most questions test high school level math applied to real-world scenarios. You have 35 minutes per section and can use an on-screen calculator.

Analytical Writing is one section with two tasks: you analyze an argument and write an essay explaining its strengths and weaknesses, then you take a position on a prompt and defend it. You have 30 minutes for each task. These essays are scored by software and human raters, and your score ranges from 0 to 6.

How to register and choose a test date

You register through the ETS website (ets.org/gre). Create an account, choose your test date and location, and pay the registration fee, which is currently $205 in the United States. You can test at a center near you or take the test at home on your own computer if you meet the technical requirements (a quiet room, a webcam, and a stable internet connection). Home testing is proctored by a live proctor who watches you through your camera.

Register at least one week before your preferred test date, though popular dates fill up quickly during peak seasons (August through October and January through March). If you need to reschedule, you can do so up to one day before your test for a fee. If you miss your test date, you forfeit your registration fee.

Building a study plan that fits your timeline

Most people study for four to twelve weeks, depending on their baseline math and reading skills and their target score. If you scored well on the SAT or ACT, you may need less time. If math or reading has always been difficult, plan for longer. Start by taking a full-length practice test under timed conditions to see where you stand, then build your plan around your weak areas.

A typical weekly schedule might look like this: two to three hours on verbal practice, two to three hours on quantitative practice, and one hour on writing. Do not cram all your studying into one or two days — spacing practice over weeks helps you retain what you learn. In the final two weeks before your test, take one full-length practice test per week and review your mistakes carefully.

If you work full-time or have other commitments, you can study less per week and extend your timeline. Consistency matters more than intensity. Thirty minutes a day for twelve weeks will get you further than ten hours in a single weekend.

Official prep materials and practice tests

The ETS publishes official GRE prep materials, including the Official GRE Super Power Pack, which contains five full-length practice tests and detailed explanations. These tests use the same format and difficulty level as the real test, so your scores on them predict your actual score more accurately than third-party materials do. You can buy them as books or access them online through the ETS website.

Third-party prep books from publishers like Kaplan, Princeton Review, and Manhattan Prep are useful for learning strategies and understanding concepts, but their practice tests often run easier or harder than the real GRE. Use them to learn, but rely on official ETS tests to gauge your readiness. Many test-takers combine an official practice test with a third-party book for strategy and concept review.

ETS also offers a free GRE Prep Now course on their website with video lessons and practice questions. If you prefer live instruction, test prep companies offer group classes and one-on-one tutoring, though these cost between $500 and $3,000 depending on the provider and format.

Common mistakes and how to avoid them

One of the biggest mistakes is skipping the tutorial and instructions on test day. The GRE gives you a tutorial before the test starts, and many test-takers rush through it. Read the instructions carefully — they explain how to use the on-screen tools and how the test adapts to your performance. Spending two minutes here can save you from confusion later.

Another common error is spending too much time on hard questions. The GRE is adaptive, meaning the difficulty of your next question depends on whether you answered the previous one correctly. If you get stuck on a question, make your best guess and move on. Leaving a question blank costs you the same as getting it wrong, so guessing is always better. You can mark questions to review later if time allows.

Many test-takers also underestimate the importance of pacing. You have roughly 1.5 minutes per question on Verbal and Quantitative sections. Practice with a timer so you know what that feels like. On test day, if you are running out of time, guess on the remaining questions rather than rushing through them carelessly.

What happens after you take the test

You see your Verbal and Quantitative scores when ready after you finish the test, before you leave the testing center or log off if you tested at home. Your Analytical Writing score arrives by email within ten to fifteen days. Your official score report is sent to the schools you designated during registration, and you can send additional score reports to other schools for a fee.

Most graduate programs use your highest score if you take the test multiple times. Some schools have score choice policies that let you pick which test date to send, while others require you to send all scores. Check your target schools' policies before you register. If your score is lower than you expected, you can retake the test, but plan your retake date carefully so you do not miss process important date.

Frequently Asked Questions

Do I need to memorize vocabulary for the Verbal section?

You do not need to memorize thousands of words, but learning common GRE vocabulary words helps. The test uses words like "ephemeral," "pragmatic," and "obfuscate" more often than everyday words. Flashcard apps like Anki or Quizlet have GRE word lists. However, many Verbal questions test your ability to understand context and logic, not just vocabulary, so do not spend all your time on word lists.

Can I use a calculator on the Quantitative section?

Yes, an on-screen calculator is provided for the Quantitative section. However, the calculator does not do everything — it cannot solve equations or graph functions. Many test-takers find that using the calculator slows them down on straightforward arithmetic. Practice with it during your prep so you know when it actually saves time.

What is a good GRE score?

A good score depends on your target program. Top-tier programs often expect scores in the 160s (out of 170) on both Verbal and Quantitative. Many solid programs accept scores in the 150s. Check the average scores of admitted students at your target schools — most publish this data on their websites. Your score matters, but so do your GPA, work experience, and process essays.

How much does GRE prep cost?

The test registration fee is $205. Official ETS prep materials cost between $20 and $100 depending on what you buy. Third-party prep books cost $15 to $50. If you take a prep course, expect to pay $500 to $3,000. Many people study using free resources like Khan Academy videos and official ETS materials and spend only the registration fee.

Can I retake the GRE if I do not like my score?

Yes, you can retake it as many times as you want. Most schools accept your highest score. However, retaking costs another $205 and takes time away from other parts of your process. Take a practice test before you retake to see if more studying will likely improve your score, or if you should focus on strengthening other parts of your process instead.
