TOEFL exam issue

I have problem like my name is appearing as ex: Ram(name) D(middle name initial) Sham(surname) on the TOEFL ticket whereas my name on passport is Ram Sham

So I called the Prometric, they said that I will be allowed for the test, but on the report card the name will appear as Ram D Sham. Now I want to ask whether this initial ‘D’ will affect my admission process for MS in US?.Because all of my documents are in format Ram Sham.

Also can I make this minor change before the exam, at the test centre.?

It will not affect your admission. If you are concerned, you can attach a Name Reference Sheet for their reference. If you believe, it was a mistake that you entered, I suggest you get it corrected before the test to avoid issues in future.
