GMAC posted on the official site of the GMAT exam a significant change in the score report process:
“As a test taker, you are given the option of reporting or canceling your scores immediately after taking the test and before leaving the test center. Under the new process, you will see your unofficial scores — Integrated Reasoning, Quantitative, Verbal, and Total — and will be given two minutes to decide whether to accept them. If you do not make a choice, your scores will be canceled.
In addition, if you decide to cancel your scores at the test center, you will be able to reinstate them within 60 days of the test date for a $100 fee. After that, scores will not be retrievable.
To get the most out of this new feature, we recommend that you:
• Know what score you’re willing to accept so that when asked whether you wish to send your scores or cancel them, you have already considered your answer.
• Understand that you have 60 days to reinstate a score you might have canceled but decide later that you want to send.
Analytical Writing Assessment scores are unaffected by the change. They are not included on unofficial score
