Does anyone know if the GRE percentiles change day to day? I'm wondering because when I got my unofficial scores, there was no % info. Is it possible for a CAT to be more difficult one day vs. another? I'm asking because the quant section when I took it was much harder than the ones on Powerprep. And it seems like most people say the difficulty level is about the same on the real GRE.

I took the GRE today. I am surprised by the quant score. On the Powerprep, I got: 610 V / 680 Q 600 V / 730 Q On the real thing, I got 650 V / 630 Q I'm shocked. I took the Quant research section and am wondering, this didn't impact my score at all did it? Has anyone else had such a large drop from the Powerprep to actual Quant score? Have the unofficial scores ever been inaccurate? I'm so confused right now...
