When the first group was nearly complete, the teachers brought out another bunker full of students, and the explanations were given again before the process repeated.
As the students began to tell each other about the rooms that had already been opened, using the information from the students who had gone earlier and stopped to gossip before moving to their new dorm, the process became faster.
No longer did they have to guess what the basic features were, that was becoming common knowledge, along with what rooms were best for what classes.
Soon, they were able to move through cadets four and five at a time, with only a small portion going to check out specific rooms to see if there was something about them that would set them above the others in their minds.
