You must reschedule or cancel your registration no later than three full days before your test date (not including the day of the test or the day of your request). For example, the deadline to reschedule a Saturday test is Tuesday. If your request is not received within three full days in advance, your full test fee will be forfeited. Test administrators are not authorized to make schedule changes.
To reschedule, you must provide
your registration number
the full name you used to register.
The fee for rescheduling is US$40. Payment must be received prior to rescheduling.
