I know that the mean keeps changing throughout the year as more scores come in. Does anyone know the official mean and SD for this year?

I took my test on November 9, 2006 and my score report was printed on November 29, 2006. According to that, the mean and SD was approximately 217 and 23 respectively, with most scores falling between 140 and 260. The SEM for this scale is six points. The SEM for the two digit score is two points.
