Reminds me of the EIT test I took my senior year in college. The test is basically the precursor to the professional engineering test--4 hours in the morning, 1 hour lunch, 4 hours in the afternoon. It was held on a Saturday and I forgot all about it. I barely made it to the testing center, forgot my ID (they allowed me in if I promised to bring it back after lunch), and had to borrow a pencil from a friend....
Long story short, I finished first in the morning, about 10th (out of ~200) in the afternoon (total test time of about 4.5 hours), and passed the test.
I suppose, in this woman's case, if you plan for failure your plans just might work out.
Oh, man. The EITs. Glad I never have to do that again!
