Derivative classification is: the incorporating, paraphrasing, restating, or generating in new form information that is already classified and the marking of the new material consistent with the classification of the source material, or the marking of the information in accordance with an authorized classification guide.
Unlimited testing is allowed if you are unsuccessful; however, you are required to wait 90 days before re-testing. You may submit a re-test exam application online via your BCEN Account after the 90-day waiting period is over.
You may only take the GMAT once every 31 days. In other words, if you take the exam on July 1, you can't take it again until August 1. If you take the exam on July 29, you can't take it again in the beginning of August; you still must wait 31 days. You may only take the GMAT five times per calendar year.
