Taking into account different learning styles, budgets, and deadlines, we’ve made it easy to find the best GRE prep course for your specific needs.

Magoosh is a wildly popular test prep company founded by graduates from the Haas School of Business at the University of California at Berkeley in 2009.

The company offers three GRE prep course options:

User reviews raved about the quality of the short video lessons, finding them easy to access and a perfect way to squeeze in study time between other commitments. Magoosh offers an app that users described as very easy to access, and learners appreciated the detailed question explanations, large Qbank, and easy-to-understand performance analytics. Students described the GRE course as offering highly organized prep, and questions were noted to be very similar to the actual exam.

Although users praised the quality of instructors in on-demand videos, some wished Magoosh also offered options for live instruction. Some students found the study schedules to be confusing, and a handful of reviews noted that certain sections felt more difficult than the actual test (particularly the Listening section).

Best for: self-studiers with a budget, those who learn best through videos, and busy students and professionals who have limited study time.

Not the best for: users seeking a comprehensive prep course with live instruction.

Manhattan Review

Manhattan Review is a recognizable and respected name in the test prep industry, having grown from a bespoke, boutique test prep company to an international educational services provider. The company was founded 1999 by Joern Meissner, a professor at Columbia Business School, after students suggested he take his efficient and effective test preparation techniques and turn them into a formal course. Manhattan Review offers several GRE prep options:

Manhattan Review is well-known for its proprietary “Turbocharge Your Prep” book series, and the company’s GRE prep books are noted to be information-packed and easy-to-understand. Users appreciated the option of online or in-person live instruction and found the instructors to be exceptionally knowledgeable and supportive. This is not surprising, given that Manhattan Review is committed to hiring not only high-scoring test-takers, but educators who can effectively communicate complex concepts to a variety of learners with differing educational backgrounds. In reviews, users appreciated the personalized learning approach, as well as the ease of finding in-person learning options near where they lived.

Lesson plans provided steady progression from fundamentals to more advanced topics, and several students praised the effectiveness of advanced performance analytics in targeting areas of weakness.

While instructors were, for the most part, noted to be very knowledgeable and helpful, some reviews mentioned that the quality of the individual instructor could vary. Some students stated that the course required substantial effort and a significant time commitment to achieve their desired score. Some lessons were reported to be more text-heavy than others, and several reviews noted that the Verbal lessons could be improved, as they were not as robust as lessons that focused on Quant topics.

FAQ (Frequently Asked Questions)

Why should I pay for a prep course when there are so many free GRE resources available online?

It’s true that there are tons of free resources to help you prep for the GRE online, but it’s also true that you usually get what you pay for. While free resources can give you an introduction to the GRE or offer additional practice questions, it’s not always clear how recent the information in these materials is. The GRE is updated every few years, which means older resources won’t apply to newer tests. There’s nothing worse than studying materials only to find out that what you studied isn't even on the test anymore. Companies that offer GRE prep courses update their materials every time there’s an official change to the test, so when you pay for a reputable prep course, you can be confident you’re study the most recent and updated information available.

I have a crazy work and school schedule, so I don’t see how I can participate in live online learning. Is there another GRE prep course option besides private tutoring (which I can’t afford)?

For those with busy schedules, on-demand or self-paced prep courses are a great way to prepare for the GRE on your time. These types of courses provide instruction through previously recorded videos or text-based lessons. You can study for 20 minutes or you can study for three hours, starting and stopping lessons when you need to. These types of courses work best for motivated learners who don’t need the accountability of live instruction, and on-demand learning is a great way to access structured prep courses without needing to adjust your regular schedule.

My biggest priority with a GRE prep course is having an instructor who can keep me engaged while explaining concepts clearly. Who would you recommend I work with?

If a high-quality instructor is your highest priority, we’d recommend working with Manhattan Review. Based on our research, their instructors are enthusiastic and committed to helping students of all academic backgrounds master the GRE and achieve their top score. Instructors genuinely care about their students’ progress and know how to explain complicated information in understandable ways.

I’m on a really tight budget when it comes to my GRE prep. Who can I work with to earn a great score without spending a lot of money?

Great test prep doesn’t have to cost a fortune, and for anyone on a budget, we’d recommend Magoosh or Achievable. Both companies offer on-demand learning options with at least six months of course access, plus video lessons and customizable study plans. Based on our research, Magoosh is somewhat more structured than Achievable, which makes it good for users who need organization, whereas Achievable might be better for those who want more control over how their test prep is presented and organized. For those who prefer text-based instruction and like to read rather than watch videos, we’d recommend PrepScholar. All three are budget-friendly options that provide quality instruction without draining your bank account.

How long should I plan on studying for the GRE?

That depends on a lot of factors individual to you, as study timelines will be different for every person. Prep courses with live instruction can be anywhere from 2-4 months long, while on-demand or self-paced prep courses don’t have an end date; instead, you get access to the online materials for a certain amount of time that ranges from one month to one year. Many test prep experts recommend allowing 4-6 months to prepare for the GRE, but your timeline might be shorter or longer, depending on if you’re in school or working, if you have a family and children, if you’re neurodivergent, if you struggle with test anxiety, or if English isn’t your first language. It’s always better to have too much time than not enough time, since rushing your prep won’t help you achieve a high score.
