<p>I was the only one in my class today to have taken AP before the US History Test today, so I had a new blank sheet where as everyone else had a sheet that was filled out prior to the test. So On my sheet, which was for my 3rd AP, I just signed by name, put a sticker on it, and filled out the info on the first page that applied to the test. But I never re-did my personal info, nor did I write a serial number, becuase I was never told to (our protor was HORRIBLE). Did I do anything wrong?</p>
