Quote:
After completing the computer-delivered GRE General Test, you will be given the opportunity to Report or Cancel your scores. If you choose Report Scores, you will see your unofficial scores for the Verbal Reasoning and Quantitative Reasoning measures at the test center. Because of the Analytical Writing essay scoring process, you will not be able to view your Analytical Writing score at the testing center.
Although you have the option to cancel your scores, consider very carefully before doing so because the score reporting choices available with the ScoreSelect® option allow you to report only the scores you feel reflect your personal best. If you cancel your scores, neither you nor any schools will ever see them and they will not be part of your reportable history. If you select to report your scores, you will view your unofficial scores on the screen and the score will become a part of your reportable history.
Your official scores will be available in your ETS Account and sent to your score recipients approximately 10–15 days after your test date.
