Oh, so it usually varies a bit depending on the school district, but usually high school starts at around 7:00. Some school may start later at like 7:30 or even 8:00. Then there's 45 minutes of class, then a break, then 45 of another class, then break etc etc until school ends at around 2 or 3 o'clock.
Actually high schoolers don't get recess at all. We stop getting recess after elementary school, so any socializing is done during lunch usually. Or in after school activities.
Yeah, usually juniors and seniors can drive off of school grounds to get food. Other students just get food at the cafeteria. But technically you're not supposed to go other places if you leave for food, but nobody is stopping you, so a lot of students go wherever they want until lunch is over.
Final exams, as we call them, are usually just taken during the school day. They change the schedule so instead of going to class, like in the periods, they just take two or so exams a day during school for about a week.
They wouldn't get transferred unless they have a history of doing stuff like that. Like, if this is the first fight they've caused, then they would probably get detention or maybe even suspended. But if they keep fighting, then they may be transferred.
I hope this info helps!
