" TOEFL program policy does not allow us to change or delete identifying information on the examinee file after the test date."
That's what they say. Some people on other forums also had the same mistake, however they managed to make ETS correct it. I am not sure whose fault it is. I even recognized this mistake way after score report arrived in paper form. Why do you believe it can be a problem? Will admission officers think that I am cheating them?
