Is there any reason why schools start early in the morning?

<p>My DS goes to a modified calendar school with a start time of 7:25 and ends at 2:30. He is in school for 9 weeks with 2 weeks off, starts in late July, finals in December before Christmas break, goes back with a new set of classes in January, and ends the last week of May. We love it. We will be going to check out colleges during his first fall break next year. The bad is he has to catch the bus at 6:15am, but he says he sleeps on the bus so no big deal.</p>
