ETS reports the score no matter what it is. (Remember there is no pass or fail in TOEFL:idea:.)
How TOEFL scoring system works?
-After you give the test, the first section (Reading + Listing) is scored by computer.
-Second section (writing + Speaking) ETS separates it by giving it number without your name or picture.
-ETS has raters all over the world how work per hour (They work from home:p)
what I want to say is
Raters can't see your picture, know your name, or know how many times you gave the test.
