pinch your cheek when you start feeling drowsy, and you'll feel much better... although after a while ur face gets red.

haha my fav teacher, makes people who sleep in class ...dance.. I will never sleep an algebra class again.. do you know why? they made me breakdance in class

You should eat a good breakfast, that always keeps me awake. Also, don't get bored, once in a while, look around the class for like 20 seconds, then focus on the teacher again.

lol i know how u feel. im very tired in class too because i have no energy whatsoever and always tend to feel bored and tired. try drinking coffee in the morening or some tea/.

hmm i know tricks to sneak sleep in class but i dun know how to prevent sleepin...when i feel tired, i sleep no matter where i am or what im doin.

participate in during class would help. also lots of note taking would keep you busy also.

Try and have what I call a powernap before each class where you shut your eyes and rest for about five minutes. You also hughlighted that you were stressed try to identify exactly what is stressing you out and address that. You could try things like yoga or a work out the night before. ciao
