What do you do when you get sleepy in class?

well algebra & geometry are not the knida subjects in which you can fall asleep.Really interesting subjects.Still, whenever i feel sleepy i try to indulge in activities like drawing something , drinking water etc..

I usually will eat some candies and drink water to prevent myself from falling asleep. :) Keeps me awake.

I use to let my seatmate pinch me if i fell sleepy in class.

Umh.... try to take a deep breath. Brain start to stop think when it less oxigen on it. After that try to keep U take dep breath. if U can;t stand anymore ask permision to go to bath room and wash ur face. Or jump jump at bath room it help me when I study sosiology

well i must say there is nothing wrong in you medically. it is just because you do not have any interest in that subject. so better option is try to maintain interest, sit at the front desk in class so that you should be aware of your lecturer in the class and do not feel to sleepy. and if still you can not hold then go to wash room and wash your face with cold water

try on chewing a coffee candy or any candy it helped me when i was in collge! i used to get sleepy also during my psychology class and even our prof suggested that we chew on something because we might get sleepy during her class.
