Winner

Target Test Prep

  • Score Guarantee: free re-enrollment if you meet criteria and don't improve
  • 5-day all-access free trial
  • Used by nearly 200,000 students

Target Test Prep takes a smart, personalized approach to GRE prep, offering data-driven tools, AI-powered analytics, and thousands of practice questions to help you target exactly where you need to improve. Whether you want to go solo, join live classes, or work one-on-one with a tutor, TTP gives you a well-structured path toward your best GRE score. It's not the cheapest option, but it's one of the most thorough.

Achievable

  • Adaptive learning: proprietary spaced-repetition system to optimize review timing
  • Online textbook of clear, well-organized GRE content with no fluff
  • Practice questions are randomized and unlimited, with 200+ quant templates and 30+ verbal sections

Achievable is a quiz-based GRE prep platform that's best for fast-paced, independent learners. You get adaptive learning, unlimited practice, and instant AI essay feedback - but no full-length tests, expert support, or tutoring. It's an efficient tool, but a bit light if you need anything beyond the basics. Still, at $199 for a full year of access, Achievable earns its better-than-average rating from us on affordability alone.

If grad school is on your radar, the GRE might be, too. The Graduate Record Examination is a standardized test used by many graduate and business schools as part of their admissions process. And while more programs are going test-optional, a strong GRE score can still work in your favor - especially if you're trying to offset a lower GPA, win merit-based funding, or prove you're ready for an academically intense program. Whether you're eyeing a master's degree, a Ph.D., or even a specialized MBA, the GRE gives schools one more way to compare applicants - and offers you one more opportunity to stand out.

The GRE is divided into three main sections: Verbal Reasoning, Quantitative Reasoning, and Analytical Writing. You'll also see an unscored or research section, which doesn't count toward your score but is used by ETS (the test-maker) to try out future questions. While that part is unpredictable, the rest of the test is very structured, and that's where GRE prep services can make a big difference. If it's been a while since you tackled geometry proofs or vocabulary in context, you're not the only one - and you don't have to go it alone, either.

GRE prep courses, tutoring, and study platforms come in all shapes and sizes. You'll find intensive programs that run like college classes, apps that help you build skills on the go, and self-paced courses with video lessons, quizzes, and full-length practice exams. Some platforms use adaptive learning technology to target your weak spots, while others give you a weekly schedule to follow. No matter what your learning style or timeline looks like, there's likely a GRE prep service that fits.

If you're someone who learns best with structure and accountability, a live or instructor-led course might be the right move. These kinds of GRE prep platforms offer both in-person and online classes with expert instructors, homework assignments, and regular check-ins to keep you on track. Prefer to study on your own time? Look for self-paced programs that you can access anytime, anywhere. Most of the time, you'll still get video lessons, practice questions, and score analytics - you just don't have to show up to class. And if you're aiming for a top-tier score or trying to overcome a particular weak area, private tutoring may be worth the investment. Some companies offer one-on-one sessions either as a standalone service or as part of a course bundle. It costs more, but it's often the fastest way to see improvement.

Not sure where to start? When comparing GRE prep services, consider these criteria:

To help you build confidence and improve your skills on the GRE, the experts at Top Consumer Reviews have evaluated and ranked some of today's most popular prep platforms. And while no course can guarantee a perfect score, the right one can absolutely help you walk into test day feeling ready to do your absolute best. Good luck on your grad school goals!

GRE Test Prep Company FAQ

What is the GRE?
GRE stands for Graduate Record Examinations. This is a standardized test required by many graduate schools in the US and Canada. The scores that a student receives on their GRE test play a role in whether or not they are accepted into a potential graduate program. Sometimes the GRE is taken multiple times until a satisfactory score is received.
What subjects are included in the GRE test?
The GRE tests students on critical thinking, analytical writing, quantitative reasoning, and verbal reasoning. An individual score is given for verbal reasoning (130-170), quantitative reasoning (130-170), and analytical writing (0-6). The test questions consist of multiple choice, numeric entry, and essay writing.
How long is the GRE test?
There are six total sections on the GRE exam. It usually takes about 3 hours and 45 minutes to complete the test from beginning to end. For verbal reasoning there are two 30-minute sections, each containing 20 questions. For quantitative reasoning there are two 35-minute sections, each containing 20 questions. The third section is analytical writing with two separately-timed tasks. One asks you to analyze an issue and one asks you to analyze an argument. After the third section, there is an optional 10-minute break for test-takers to get refocused for the remainder of the exam. You may be asked to complete an unscored, research section at the end of the test.
How long should I study for the GRE?
Most people would agree that you can't cram for the GRE. If you do, you'll likely get an unsatisfactory score that reflects how little effort you put in. It is recommended that you heavily study for at least 4-12 weeks before attempting the GRE. Many test prep courses are designed to help you study over the course of a year, to make sure you are familiar with the material and are able to obtain a high score on your first try.
How much does it cost to take the GRE?
The cost for the GRE test can vary slightly year to year. Most recently, the fee was $213 for test-takers within the United States. If you are signed up to take the GRE and need to reschedule, you'll pay a fee of approximately $50 to have the exam administered at another time.
How much does it cost to use a GRE test prep service?
Many GRE test prep services offer some free resources to get you started with your studies. For tutoring services or monthly subscriptions to books, practice tests, flash cards and more, you can expect to pay anywhere from $150 to $2,000. Some of the most expensive courses include access to materials for a year or more and usually guarantee a certain test score. They include everything you need to succeed and feel confident when you take the GRE.
What types of study resources do GRE test prep services provide?
Not all test prep services offer the same study materials for the GRE. You'll find a mix of resources like practice tests, one-on-one tutoring, practice essay questions, vocabulary flashcards, diagnostic tests, strategy sessions, and more. The tools that you need to get a good score on the GRE are readily available through many different GRE test prep services.
How often can I take the GRE?
If you are unhappy with your GRE score, you can retake it every 21 days. However, you are only allowed to take it 5 times within a period of 12 months. Taking the test multiple times will not hurt your chances of getting into graduate school, since you can choose to only submit your highest score.
