So the competition is over and there's still no winner.  Why?  It appears the database I use to pull the Exam Challenge data is undergoing a backup and restore and thus it's offline Sad

The score for first is close.  Green holds a 3 point margin over Blue, and Green leads the final unresolved challenge 10 exams to 7.  It could reverse when I pull the final data.  So Blue could tie it if it wins the Exam Challenge outright.  

Stay tuned - I'll pull the data first thing Friday morning and we'll see who wins $5000!
