Who Needs a GRE Prep Course?

Most graduate programs require the GRE for entry. The GRE is challenging, and high scores are critical. Your GRE score is a factor not just for admissions but can also influence the amount of funding you’ll receive. Many graduate programs also use GRE scores to determine scholarships, fellowships and academic financial aid.

Determining your best approach to preparing for the GRE can be tough. GRE prep courses can be expensive and time-consuming. Do you need a GRE prep course? The answer depends on a lot of factors.

Factors to Consider

  • Improvement needed – take a free GRE practice test to see where you stand. If your score needs improvement, a GRE prep course may be a good option.
  • Study discipline – if you routinely have trouble maintaining a study schedule, you’ll find that a prep course is worth it.
  • Need for encouragement – if you need encouragement, feedback and motivation, a prep course with an instructor (either in-person or online) is a good option.
  • Learning style – if you have a history of successfully studying with books, a self-study approach with a good GRE prep book may be your best plan.
  • Budget – GRE prep courses can get expensive. If money is tight, consider our best value recommendation, or self-study with GRE prep books.

Benefits of a GRE Prep Course

  • Score improvement – the top GRE prep courses will guarantee a score improvement of 5 points or more.
  • Comprehensive study plans – GRE prep courses will help you craft, and stick to, a customized study schedule that works for you.
  • Identify strengths and weaknesses – the best GRE prep courses offer advanced diagnostics to identify the topics you need to focus on.
  • Simulates actual test – the online exams included in a GRE prep course do a great job of simulating the real GRE.  Magoosh’s dashboard predicts your GRE scores and compare you to other students.
  • Quality instructors – courses that include live instructors will help you with efficient strategies, motivation, and one-on-one feedback.

Why a GRE Prep Course May Not Be Your Best Option

  • Expensive – the best GRE prep courses may be over $1,000.
  • DIY alternative - self-study using prep books may be a cost-effective alternative
  • Time-consuming – prep courses often require significant study/prep time
  • Instructor-dependent – if you opt for an instructor-led course, the quality of your instructor will be a significant factor towards your success.

Bottom Line - If you need a top GRE score and have the budget, a top GRE prep course is a great option.

Princeton Review Summary

The Princeton Review’s GRE Prep course provides test takers with more than 175 hours of GRE prep resources online, which includes lessons, feedback, and test-taking strategies. Overall, the GRE prep course by the Princeton Review offers a plethora of quality GRE prep content and innovative tools like Drill Smart – a practice technique that selects practice questions based upon the areas of improvement highlight by a test taker’s answers.

As a test taker’s abilities improve, Drill Smart adjusts each question’s difficulty to enhance a student’s chances of maximizing their GRE score. The Princeton Review’s lessons are straightforward and customizable, although a video professor is always available to help guide the test taker to the desired lesson or exam strategy.

Live chats with professors and cohort members offer opportunities for group discussion or further explanations of the topic at hand. 

The Princeton Review offers in-person courses, online classroom courses, and self-paced courses. The least expensive Princeton Review GRE Prep course is the self-paced, comprehensive version, offered at $499 (often on sale for $399) for both Math and Verbal modules. 

Other versions come with unlimited access to the Princeton Review's live sessions and original content. Additionally, there are more than 2,500 practice questions, more than 60 video lessons, more than 60 Adaptive Drills, and eight practice tests. A GRE expert reviews the course student's written essay as well.

Princeton Review's satisfaction guarantee is unmatched by any other program. Course students are permitted to re-take the course if they are unsatisfied with the after-course score. Plus, if a test taker's rating does not improve, they will be issued a full refund.

Achievable Summary

Achievable offers a very affordable GRE prep course. The course is offered for $199 and students will get access for 12 months. The course includes 9,999+ practice questions and practice exams for each subject and lecture materials for everything tested on the GRE. 

In total, there are 89 chapters of GRE review included in this course. Each chapter has various sub-topics that are reviewed. These sub-topics help breakdown the content into easier to digest sections. 

The chapters are in a textbook format. There are helpful charts, tables, and images to explain more concept topics, which we really liked. However, there are no video lectures included. This can be looked at as a pro or con, depending on what type of learner you are. 

Achievable prides themselves on their adaptive learning method. As you progress through the course, their system learns about you and personalizes the study program based on your strengths and weaknesses. 

This adaptive learning technology can be seen on the users dashboard. There is a content progress section that tracks your progress as your read each chapter and mark it as complete. When you mark a chapter as complete, the system automatically chooses specific review questions for you to review.

Users can review these specific questions in the memory progress section of their course. This section of the course is meant to help you actually learn material and continuously have the ability to review it until your test date. 

One of the coolest features is the upcoming workload feature. Their system will determine the best time for you to review a certain subject based on how much (or how little) you already know. Users can choose to follow this schedule or to follow their own schedule. 

Overall, Achievable has a nice GRE prep course. The user interface can be a little confusing at the beginning, but they have a section explaining how the course works, so you should be able to figure it out. We are not huge fans of the textbook-based learning approach, but they do a great job of explaining complex subjects.

Manhattan Prep’s course is a self-paced adaptive learning experience that is accessible 24 hours per day, seven days a week. The GRE prep content is taught by instructors who have scored in the top 1% of all GRE scores.

Coursework for Manhattan Prep's GRE course includes GRE Official Study Guide, thousands of practice GRE questions, more than 75 video lessons, plus six complete GRE practice exams.  

The GRE prep course guides students through a learning stage, a reinforcement stage, and a test stage with consistent student feedback. Manhattan Prep offers a 7-day free trial to give students an experiential opportunity using the Manhattan Prep interactive platform. There are three access periods from which to choose – One-month access at $249 (or $22/month), Three-month access for $349 (or $31/month), and the Six-month access program for $399 (or $36/month).

Manhattan Prep is one of the few GRE Prep companies that do not include a higher score guarantee.
