In Spain you could select early morning or late classes in high School and in University. Late are usually there for the people that work. I did chose sometimes early morning, sometimes late depending on my job or my preferences. It made no difference at all. Just a different schedule. If you have early classes you need to sleep early. I believe most people that never experience late classes are just idolizing, because what I see is most people get to bed late and that is the main problem that they have. There is a tendency on humans beings of going to bed later, because everyday we can delay two hours going to bed but we can only change one hour ahead, so most people delay going to bed following friends on facebook or doing whatever they like. Just change your habits.
