If you need to reschedule or cancel your registration, you can do so up to three full days before your test date (not including the day of the test or the day of your request). That means if your test is on Saturday, you must reschedule or cancel by Tuesday.
To reschedule online or by phone, you must provide your registration number, and the full name you used to register. The fee to reschedule is US$60, and must be paid before you can reschedule.
If you cancel by the 3-day deadline, you’ll receive a refund equivalent to half of the original test fee.
