No waiting period to take alternate version, 60 day waiting period to retake same version, can try up to 4x before being denied admission, cannot administer the same test more than twice in 90 days. If denied must wait 6 months from date of 1st test or 90 days from date of last test, whichever is later, can delay entry after passing the exam.
