The first test the immigrants had to pass became known as the "six second medical exam." As the immigrants climbed the stairs to the Great Hall, doctors stood at the top and watched. They were looking for anyone having difficulty coming up the steps. If a medical problem or disability was suspected, one of seventeen different chalk marks was put on the person's clothing. They were then sent for a full physical examination. If they weren't marked, they went on to wait in the Great Hall.
