In undergrad some professors were really particular about having NOTHING out during tests, I had to get a dr's note to have chapstick (label torn off) during midterm/final exams. And I submitted it to the GMAT board for approval, since their rules are just as strict. Waiting to hear back. Started after getting debilitatingly windburnt skiing years ago, it's a complete psychological thing now.
Also, I learned the hard way not to leave one out in the sun in the car...always have it in a compartment somewhere.
