Question 10 of 10

## Diagnostic GMAT Scores, Answer Explanations, and Study Plan Recommendations

After you take the quiz, enter your email [optional] to get a copy of your Diagnostic GMAT scores along with answer explanations and custom recommendations for your GMAT exam prep. These recommendations divide test-takers into four different “buckets,” based on their abilities in both Quant and Verbal. These buckets are labeled Group 1, Group 2, Group 3, and Group 4. Each group comes with its own special recommendations for GMAT practice.

The GMAT prep recommendations will include a recommended study plan and additional tips and advice, based on your performance on the free GMAT practice tests. The study plans we assign to each score group are all three months long. This, typically, is the amount of prep time that most test-takers need in order to get excellent GMAT scores. With that in mind, if you feel three months isn’t the right timeline for you, you can pick a different study plan from the Magoosh GMAT exam study plan page.

## How to Use these Free GMAT Practice Tests

As mentioned above, this GMAT Quant quiz should be taken with the GMAT Verbal Quiz, and you should follow the recommendations for your score group.

Beyond that, these quizzes are a great way to start identifying your strengths and weaknesses on the GMAT exam. Rather than simply looking at your score on these free GMAT practice tests, you should carefully examine exactly which questions you missed, and why. The answer explanations in the summary you receive at the end of the test can really help you understand which concepts are in play for each question, and can give you insight into the kinds of things you should be studying. You may find you need to focus on Data Sufficiency, or on algebra, or integer properties, and so on.

Above all, remember that the GMAT scores you get today are not the GMAT scores you’re stuck with. If you scored low on this diagnostic test, don’t feel bad! This test is meant to be a starting point toward your best possible GMAT scores. And that road to better scores includes many additional materials, such as full-length free GMAT practice tests from the Graduate Management Admissions Council, and other materials, both official and unofficial. Good luck on your road to GMAT exam success!
