Forty Hours Until

Oh boy, oh boy, oh boy.

I have never been this worried about an exam before.  I think because I do not feel prepared, but my practice exam says I know a lot.  I guess I will just have to study some more.  Except now, I am sort of tired. 

I wonder if I am studying effectively?  My grades are high, so something is working.  Or as my professor said..."do not change anything now, you're evidently doing something right"

These are the postcards that I received that I like.  More than luck is preparation. I am doing that.  I just have to keep going.
