School starting time

1. For a highschool student the recommended sleeping time is 8-10 hours of sleep.

1.1. in order to get 8 hours of sleep you would have to go to bed at around 8:30

2. What do studies show is the best time?

2.1. "The American Academy of Pediatrics say that middle and high school should start at 8:30am"Schools Start Too Early

3. School starting can have a big role in a students grades in school.

3.1. Many times after school I have came home and went to sleep. This in return messed up my sleeping during the night not letting me go to sleep at a resonable time. So then the next day this leads to a bad day at school because I am tired at school.
