From all sides

Well, I have 3 tests within the next 48 hours. OB, Stat, and Accounting. I suck at all three of these. I've got a really, really bad feeling about accounting already. I just don't have the time to do all of these at once like this. The only thing I can do is cut back on the sleep and thats not good when you need to be able to reason. I had been hoping to do well at all of these things but this kind of kills me.
