As I've said before, you should take TOEFL as often as possible once you hit 95 because the difficulty varies from test to test. So this is a disappointment.
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.
Please use English well!
