Actually now I am really not sure about the exact wording of what I said in my post above. I get confused with these types of things. Maybe you can bring more than the just pencils, photo ID, and admission ticket. For example consider the following quotes from the URL I referenced above:
You may wish to pace yourself with your own watch, but the supervisor is the official timekeeper . . . Watch alarms and clocks on cell phones are not permitted.
So maybe watches are allowed but apparently the watches can’t have alarms and the watch can’t be part of a cell phone. But wait what is this next quote:
using any aids in connection with the test, such as: mechanical pencils, pens, pagers, beepers, calculators, watch calculators, books, pamphlets, notes, rulers, highlighter pens, stereos or radios with headphones, telephones, cell phones, watch alarms (including those with flashing lights or alarm sounds), stop watches, dictionaries, translators, and any hand-held electronic or photographic devices.
So I guess legitimate watches also can’t be stop watches and they can’t have calculators built in or maybe they can but you just can't use those features . . . i just don't know. Anyway, it appears a safe bet would be a simple old school watch with the big and little hand or also some really bare bones digital watch. Oh and hey look erasers do seem to be allowed per the following quote.
Take 3 or 4 sharpened soft-lead (No. 2 or HB) pencils and a good eraser. Pencils and erasers will not be supplied at the center.
However, how sure can one be when they have the following earlier statement:
Other than ID, personal items are not allowed in the testing room.
Basically, I really don’t know what to say except that if I was going to take the test again then all I would bring would be some wooden #2 pencils with erasers built in to the pencil, my photo ID and my admission ticket.
