Wow that is interesting, maybe even the Italian system of a few hour break in between to go home and have lunch. If I had to choose however, I would actually boost it up, my school starts at 8:30 and ends at 3:20. I would prefer something like 10:00 to 4:50, I feel like it allows for more sleep for students who find themselves sleeping too late, but also encourages doing work in the morning in stead of cramming it the night before. It also provides the opportunity for students to arrive eat school on time, it would fix the debate on whether lunch or recess is first and also allow events to be run in the morning without holding students back, also evening events do not cause students to be held back for as long. Also it provides enough time for students to get home and have dinner instead of get home, snack then have dinner.
