I want to reschedule my exam. How much time ahead do I have to do it?
To be able to reschedule your exam, you need to do it up to 15 days before the exam’s original scheduled date and time.
Rescheduling the exam 14 days ahead of its date, and up to 48 hours ahead, will incur an extra fee of 25 US$.
It is not possible to reschedule the exam less than 48 hours before the date, so be sure to do it, if you wish, before that.
