Like others have said, it depends on the testing center. However, a college friend of mine who took his test in ND said that someone accidentally ripped their scratch paper during the PAT and the proctors came in and immediately took it away and replaced it with clean sheets because they thought that he was using it for some form of angle measurement or something like that. That said, nothing like this happened to me during my DAT (although I prefer the hands flat on the table method anyway...) Also, at least in my testing center, I think I was the only one taking the DAT that whole day and everyone else was taking other random tests, so I doubt that the proctors would keep that close of an eye just on you during your PAT...but I don't know...
