Imprisoned by the bell?

Come to think of it, mental wards and schools really aren't too far off from each other. The biggest thing they share in common is that they are scheduled down to the minute. As school, we have to stay in one specific place, until the clock tells us otherwise. We have a system of bells to tell us when we're allowed to leave that place, and another bell to tell us when we have to be in our next place. We can't leave the school during the day, and we have others responsible for us while we're there.

We get a small amount of allotted social time too. During lunch we get to socialize with each other, but only under the watch of several teachers to make sure we don;t jump around on the tables or set the ceiling on fire, or pull a fire alarm. Once that time is over, we're ushered back to our respective rooms by the bells.

Our school is by and large split into different academic groups during the majority of the day. The kids who are able to handle the tougher curriculum are in honors classes, and tend to only be in classes with the honors kids. In general, the kids who take cp2 courses are with all the other kids who take cp2 courses for most of the day, because most of the day consists of those academic classes. So our school is split up by class level just like the mental ward is split up between the different types of patients.
