Hi Rachel--
I took the revised GRE last monday (August the 1st). At the end, there was a message displayed on the screen that was exactly the same as the one you get at the end of the POWERPREP II practice test (in fact, my scores were the same). It was something like:
" Your test score according to the new scoring scale is not available, but your performance according to the old GRE scoring scale is:
QR: XXX-XXX
VR: XXX-XXX "
So, you don't get your exact scores, but only a range for them.
I hope that helps.
