You can take the GRE General Test once every 21 days, up to five times within any continuous rolling 12-month period (365 days). This applies even if you canceled your scores on a test taken previously.

The retaking a test policy will be enforced even if a violation is not immediately identified (e.g., inconsistent registration information). If the violation is identified after registration but before the test administration, the testing appointment will be canceled and test fees will be forfeited. If the violation is identified after test scores have been reported, the invalid scores will be canceled, score recipients will be notified of the cancellation and test fees will be forfeited.
