Idk, it is a matter of preference. I was hard for me to get up for school because I went to sleep late, because I didn't care enough about school. If the school started (and ended) later, then I'd to sleep even later. What mostly matters after all is the number of hours you slept. When I got to the army I needed to constantly get up at around 0530. What I found out is that it's not a problem for me (and I firmly believed it would be nearly impossible) if I go to sleep early enough. It worked for most of people around me as well. Since then I don't think getting up earlier or later really matters, I decide it based on the stuff I want to do and not the other way around.
