School?

In the latest day in the life video seemed like the older kids don't even go to school full time? Paislee was home at 11 and ordered lunch and SaiDee got lunch and then went home and nayvee went late cuz she didn't have a class in the morning? So odd to me. Where I'm from you go to school 7:30-2:30 no matter what. We didn't have half days and only seniors could come an hour late or leave an hour early so wondering if they do hybrid of online so they can film and such!
