If you’re planning on going on to graduate school, passing the GRE is one of the biggest hurdles you have to face. The GRE, which stands for Graduate Record Examination, is like the SAT or ACT for graduate school, and more than 500,000 students take it each year. The GRE has three sections — quantitative, verbal, and writing — and the best way to increase your chances of successfully passing it with a high enough score to get into graduate school is to take the preparation seriously. To help with that, we’ve compiled a list of 10 of the best GRE prep courses below.

Our Ranking Criteria

While all prep courses we’ve listed below have proven successful in preparing students for the GRE, we also wanted to make sure we included those that were easy to fit in your schedule, offered a variety of learning formats, and could be personalized to your needs.

Flexible scheduling and adaptable formats

If you’re taking the GRE, you’ve either already successfully completed your undergraduate degree or are in your senior year, and this means you’re more likely to also be holding down a job or have family commitments that can make test prep harder to fit in. That’s why we’ve tried to include courses that have flexible scheduling so you can work at the time that’s most convenient to you.

Personalized instruction

One thing that makes a GRE test prep course stand out is its ability to be customized to the needs and preferences of the learner. Maybe you prefer to read material and take practice tests on your own, or maybe you need to watch videos or have one-on-one sessions with a tutor to really integrate the information. We tried to include courses that were able to be personalized to your preferred method of instruction and strengths and weaknesses.

Choose the Right GRE Prep Course for You

When you’re going through this list and trying to figure out which course is the best for you, you’ll need to consider several factors. We’ve listed a few of the most important steps to take when evaluating GRE prep courses below.

Calculate prep time

How much time you need to prepare for the GRE depends on whether you’ve taken the test before, how confident you are about the material, and when you need to have a score by. Those who are very strong in math, for example, may need less time since they’ll only really need to make sure they’re prepared for the writing and verbal sections. If you’ve taken the test before and are retaking it for a better score, you won’t need as much time to prep as a first-time test-taker.

Consider your learning style

Your learning style is an important part of choosing a GRE prep course that will work best for you. Most of the courses on our list have multiple formats to cater to all learning styles, but if you know that you are very strong in one area, such as visual learning, this can be a determining factor in which course you choose. If you’re not sure which type of learner you are, you can read descriptions of the different styles.

Compare costs

There’s a wide range when it comes to pricing for GRE prep courses, and your budget will be a big factor in which one you choose. You can find quick-prep courses and question banks for less than $100, but full-length prep courses with one-on-one instruction and multiple practice tests can cost up to $8,000.

Look for must-have features

When you’re comparing GRE prep courses, look for as many of the following features as you can find:

  • Flexible class offerings, including in-person and online formats
  • Lots of practice tests, including full-length options to get an idea of pacing, and practice questions
  • One-on-one tutoring
  • Personalized instruction and content
  • Money-back score guarantees

GRE Prep Frequently Asked Questions

What are the important dates for taking the GRE?

The GRE is offered year-round at Prometric testing locations across the country, and the test also now has an at-home testing option as well. If you’re planning on taking the test at a testing center, you will need to make an appointment for your preferred date early on, as they are accepted on a first-come, first-served basis. It takes around 10-15 days for scores to be reported, and you have to wait 3 weeks before retesting. Keep in mind that you can only take the GRE five times in one calendar year, so it’s a good idea to make sure you’re prepared before retesting.

Are there accommodations for disabilities?

The GRE does have accommodations for those with disabilities, including text-to-speech software and braille. All accommodation requests have to be approved by ETS Disability Services prior to scheduling a test date.

Where can I find practice tests?

The ETS website has some free GRE prep tools, including two free practice tests you can take through your ETS account.

How early should I prep?

It’s recommended to start preparing for the GRE at least four to 12 weeks before your test date. Those who need to spread out the test prep because of other obligations or just wanting to work at a slower pace may want to budget as much as four months. A general rule of thumb is that the longer you have been out of college, the more time you will need to prepare.

How many practice tests should I take before the actual exam?

It’s a good idea to take a practice test before you begin prepping to get an idea of where you’re starting from and if there are any areas you’re already strong enough to skip. You want to focus your test prep on weaker areas. It’s recommended to take another practice test toward the end of your prep course to make sure that you’re score is improving and in a range that’s going to work for your graduate program.

How long are most GRE prep courses?

Most GRE prep courses take one to two months to complete,  but this depends highly on how much improvement you’re trying to see and how much time you have to devote to test prep. If you’re just going through a practice test and a few questions, it could be as short as a weekend. However, some of the more intense courses can take 6 months or more.

Is GRE prep worth it?

Anytime you’re prepared for a situation, the outcome is likely to be better, and this is true of taking the GRE. Your GRE scores will really make an impact at your target schools if you aim to score higher than their standard range for admission.

How much does GRE prep cost?

How much you should expect to spend on a GRE prep course depends on the program, the time involved, and what features are most important to you. On the low end of the spectrum, you could pay $100 to $150, and on the high end, it could be thousands. You’ll also need to look at whether it’s more cost-effective to go with a subscription service that charges by the month or a one-time fee that gives you access to the entire course.
