I agree. Plus, school schedules are also inherently incompatible with true night owl behavior. So, for what it's worth, there's no additional data point to compare against, say, a school that starts later in the day. I think a more useful metric would be university courses where students have some degree over selection. Otherwise, this "study" isn't so much about how terrible someone's academic performance is because they go to bed late as much as it is a study that simply confirms sleep deprivation affects academic performance (fancy that).
