i wouldnt take what other people are saying about answers too seriously.  Last year i went from low 60's according to this forum to low 80's when official key came out.  A guy i work with went from high 80's to high 60's.  so DONT BE GUIDED BY WHAT PEOPLE SAY ON THIS FORUM..  your just going to drive yourself crazy for the next 5 weeks..

Maybe, that happened to you and other few people in last year. My friend told me he got 70 according to this forum. And he still got the same 70 after the official key came out. You are right it may not 100% accurate but this is very close to the official answer. Good luck.
