<human>: Provide a brief overview of the text.

My sister is 16 and a junior in high school in Massachusetts.  She transferred to this school for the incoming year more than two weeks before school started and when she enrolled they told her they would get her schedule together the first day. Well. Today is the second day and she came home again with no schedule.  She attends a large underperforming city school that has a 7 and a half hour day.  So she has been sitting in the auditorium doing nothing for that time. 
There are about 70 other kids without classes. THat was at the end of the day today but there were about 30 more yesterday.  They told her it could be a few more days before there is a schedule. Also if she were to leave/not show up they would count it as an unexcused absence. 

This just doesn't seem like it is legal seeming that in my state you can't have study halls.
<bot>: My sister is at  a new high school and doesn't have a schedule and they are forcing her to sit 7+ hours and do nothing. Is that legal?
