Really would need more info in order to offer any insight here. What tests were you writing when you got that 160-163 range? What tests did you take that you got lower than usual on? What is your favorite color?
@lschoolgo I see the "pre-program" bit now. Sorry. Still I must say that the conclusion is supported by info re:the completers so the non-completers are irrelevant.
Nope folks, not gray yet. We will keep you posted! Believe me, I am stalking the Twitterverse and will bring you the info as soon as I can (unless @"Mike Spivey" beats me to it!).
