I went to highschool in the early 2010s, and I started 8:30am. Sports would start at 2:45. Senior year, because of the stress of college applications, we would start at 10am (you could still take the bus and use the extra time to meet with the college counselor if you wanted). It seems much more humane.
Why does the class portion of the day _need_ to be 8 hours long? My school is still considered one of the highest-ranked in Texas, if that matters, where it’s not uncommon for 25%+ of a graduating class to go on to Ivy’s, so I question if it’s really necessary to be sitting in class for longer than that in the first place.
