How can i stop falling asleep in class?

take naps later in the day if you like staying up late

Holy hell I do it all the time! Try opening your eyes as far open as you can when you feel that annoying feeling in your eyes like your head is going to smack the desk. It really does not matter if you get alot of sleep. Whenever a teacher turns on the projector or dims the lights I totally konk out! Also it helps if you keep a box of ice breakers with you. They wake up your senses really fast.

i have to get up at 6:00 so i go to sleep around 9:30-10:00

Experts say around 8 hrs is the recommended hrs, so maybe around 10 PM.

10 pm or 11 pm.

lawl. just sleeep in class. i do . its pretty much the best time to sleeep.

Sometimes 6-7 hours isn't enough. I know this friend that sleeps at 7 PM and gets up at 5 AM. That's 10 hours of sleep for her. Maybe you need to sleep an extra hour or two. In the morning try having coffee ONLY on those days when you barely got any sleep. Also exercising in the morning really wakes you up so maybe you could do push ups or walk to school I suggest going to sleep at 10 :)
