Exam day Wednesday

I have my 4th exam of the semester today. I have been studying non-stop for days now. I don't know if it will help my grade or not though because my mind is mush. I get like that sometimes when I study and study and study and by the time I'm done I feel that things just get mashed together and I don't know what is right or wrong. Othertimes I get like that and than sleep on it and the next day things come together. I'm really hoping that is what happens today. Wish me luck.
