I'd like to know too...it seems that some people are scoring 10-20 points higher on the real test, which is a good sign =)
I took the sample test that is currently online (for the pre-July 15 test) and the sample test that was in the printed booklet released in 2005 (this test was the one they used in 1993, apparently). I got like an average of 10 points higher on the 1993 one...they changed some of the questions on the new one and those are the ones I missed. =\
