No, but it is far too demanding. There is a dedicated room. Many schools have dedicated rooms. Some put in spurts. Some put in 16 and 17 hours seven days a week depending on where we are in the project.
Every quarter there are students that sleep in the room.
It is terribly difficult to let the students off early. Remember it is their project, not ours. The level of commitment is there. We have found that the only way we can actually reward them, and the director often regards his job not teaching anything, but trying to keep 18 really hard-working students somewhat sane during the quarter. When we do that, at least half don't come in early.
