"An important piece of the story is that it's not just about making the life of a teenager easier by saying maybe we can make classes later," said Benjamin Smarr, a postdoctoral psychologist at the University of California at Berkeley who studies circadian rhythm disruptions and learning.

As it turned out, taking a class schedule mismatched to your biological clock took a toll on students' grades, as the chart below shows.

Early-rising "larks" had a grade advantage in morning classes, they found. Night owls performed better in afternoon and early evening classes, but the researchers also found these students tended to struggle more than those with earlier circadian rhythms in general. The researchers believe this was because their schedules were the farthest off "normal" class schedules, and the actual class times often varied significantly from day to day, making it difficult for these students to develop any consistency.
