One last chance

Tomorrow I am taking a DSST and this will be my last chance to graduate by August so I am crossing my fingers to just pass this time. Twice I have taken a science clep/dsst and twice I have missed the score by one point. If I miss this one again, I will have to believe I am cursed because seriously? It's not like I'm not studying each time or studying hard because I am. The nerves are going to really hit tomorrow afternoon.
