Same for high school. I was one of the furthest-out kids so we started super early. I would later be in an AP class that required I get to school on my own by class start at 07:15. We finished at 14:30, but those of us in band kept going for a while. Then any other clubs/activities. When I did theater, I'd get to school around 7am and not leave until 11-12 hours later.
