Each institution has specific deadlines for submission of test scores. You should therefore get in contact with the institution you are interested in and allow appropriate time for the receipt of scores by the Admissions Office. Test administrations are available throughout the year.
Can I take the exam multiple times?
Yes, you can retake the test as many times as you wish, but you cannot take it more than once in a 12-day period. If you already have a test appointment, you cannot register for another test date that is within 12 days of your existing appointment.
