not a lot. I sleep a lot on the weekends but due to homework and the weekend messing up my sleeping schedule, I barely sleep during the week. I'm only getting 5 hours tops tonight. That's if I fall asleep in the next 10 minutes
depends
when i'm in school i can either pull all nighters or sleep 12 hours if it's the weekend
regularly, 7-9 hours (i noticed this during thanksgiving break)
