When it comes to acing the GRE test, there is one rule—practice, practice, practice!  Research proves that taking practice tests is one of the most effective ways to prepare you for the actual GRE. The more practice exams you take, the better you’ll know the material and will hone your test-taking strategies for test day.

The best GRE test prep course should have multiple practice exams. That way, you don’t get stuck taking the same test that you will probably memorize.

Best Pick for Practice Tests: Manhattan Prep

Practice Questions

practice questions

The same methodology applies to GRE practice questions—the more, the better! However, the number of questions can’t be the only factor. The course must also be adaptive to your learning style and pace.  For example, Magoosh only offers 1,000 GRE practice questions, but using their personalized approach to learning creates customizable practice quizzes based on your strong and weak areas.

However, in this case, both Kaplan and The Economist offer the most practice question and provides a personalized approach to your academic progress and learning style.
