The average adult needs 7 hours of sleep a day....
but NS you need to sleep by 1030 and wake up like around 5
the earlier you sleep, the earlier you wake up.....
since after my EOY exams i usually sleep at around 3 and wake up at
around 10....
Though sometimes when i go sleep at my fren house, i could sleep at
6am and wake up at 7am coz we usually go out together to meet other
friends the next day
