Could some of the guys who have taken the GMAT already give some insight on what things are to be prepared or kept in mind for the test day other than the tests itself.
Here are some samples points to contribute on:
Is it aadvisable to take a sweater/jacket inside?
Long sleeves or short sleeves? Shirts or jerseys?
Handkerchief? paper napkins?
Leather or sports shoes?
mental/physical preparation before taking the test but after arriving at the test center?
on the computer but before the test begins?
on the computer but after the test finishes?
after the test finishes?
