On week days, usually about 6 hours. Most of the time I am up late doing homework. The nice thing about being homeschooled is that I sorta (not really) get to sleep in. On weekends I generally sleep about 10 hours. I looooove sleep, so I use Saturdays as a time to catch up on what's been lost in...
Most nights I'll go to bed at about 11:00 PM-12:00 AM, but I often wake up during the night. On weekends, I'll stay up anywhere from 1:00 AM to even 5:00 AM sometimes. The internet is just so much more tempting than sleep. After nights like those, I love to sleep in till about 10:00 AM.
