The first day of sophomore year is very like the first day of freshman year, so far. Find your assigned homeroom on the lists in the entry hall, go to your assigned homeroom, sit down and wait for something interesting to happen while schedules and student handbooks and things are passed out. 

The cover of the student handbook Bella is handed seems to be a bad printing, the colors vaguely off and the text displaced slightly relative to what you would expect. It's vaguely disconcerting to look at, but the interior seems perfectly normal.
