In which I am doomed

I have to take a placement exam on Friday to (attempt) to get out of retaking Algebra 1.  As I started reviewing the practice exam I realized I am completely doomed.  I can't even remember how to factor or multiply fractions anymore.  Strangely enough, it's some of the more advanced math I can still remember.  Think of me on Friday as I labor through the 90 minute exam. Ug.
