One of these far good challenges
It is foreshadowed that Susan is at a zenith, a highpoint in her life. This, however seems to be the last highpoint that she will ever be at, insinuating that the rest of her life was much more depressing and less exciting.
I would oppose it. Studies show teens biological clocks naturally want to go to bed later and wake up earlier. By making school and hour earlier this makes teens more groggy especially because their bodies do not want to go to sleep earlier so this can cause sleep deprivation which will make school work less concentrated and makes teens attitudes about school worsen.
