My daughter will be in 4th grade, and my son will be in 3 day preschool. Both of their schools start at 8:30 so I will be dropping her off earlier, then him at 8:30, and then off to my work by 9. Their schools end at the same time, too, but they will both be in after-school care until I can come pick them up. Their schools are only a few minutes apart from each other so it shouldn't be too bad.
My daughter is always up by 6:30 and my son fluctuates between 6:30 and 7. I, however, don't get up until 7:20 or so.
