Kaplan is considered to have the best GRE courses because it offers programs for students who want to study online, individually or at a testing location. It also has installment payment options for those on a budget. If you want to purchase test booklets, Kaplan provides workbooks and practice tests on its website, but bookstores like Borders and Barnes & Noble also sell Kaplan testing booklets. One major benefit of the Kaplan experience is the availability of free paper sample tests that help diagnose weaknesses and strengths, allowing you to focus on studying the right materials for the GRE.
The Princeton Review, also considered to offer one of the better GRE test prep courses, has several options for GRE test preparation, programs for different budgets, and guaranteed satisfaction and score improvement. Its testing centers offer one-on-one tutoring sessions and group instruction, and it also has a GRE test prep book series in addition to a guide for graduate admissions and scholarship opportunities. Students can self-study with online courses or they find workbooks at local bookstores.
PowerScore offers test preparation in GRE, LSAT, GMAT and SAT. It teaches GRE courses at testing centers, but also has live GRE instruction on the web. Students choose weekend courses with 16 hours of instruction, or in-person tutoring, phone tutoring and admissions counseling. The best option at PowerScore may be its personalized GRE preparation solutions with one-on-one tutoring, individual telephone test prep sessions and packages. PowerScore also has verbal and quantitative questions from actual GRE tests that students use to prepare for the exam.
Educational Testing Service (ETS) administers the GRE as well as 50 million tests annually. Since it's the official test preparer, it sells versions of the exams as preparatory workbooks at its online store. Each workbook comes with a CD-ROM with diagnostic tests, example essays and strategies for taking the GRE. Once students register for the exam, ETS also provides sample practice booklets.
