You get three hours to take the test. They don't let you out until that time. So, you do the math
It starts at 11:05 am . That's what it says on my schedule, and i'm pretty sure everyone has to take it at the same time, so If i were you I would ask a friend, call the school, or w/e and find out what time it starts because my schedule says 11:05 am... and my schedule was created by USNY - they create the times. soo, get at that!
