@HalfwayToTheStars I slept at 1-2AM (had to get up at 5:50AM for school). I started falling asleep (like involuntarily) in class and my memory suffered pretty badly. I was stressed and agitated all the time, so to be honest, I have no clue. You need sleep at least though since lack of sleep will hurt your memory, which will suck when you're trying to study and remember things.
