October GRE biased?

Hey all,
I'm taking the October GRE just because I'll get to know my scores before I apply to places...
Though I have a concern... At my school, nobody else at all is taking the October test since they think they need more time to prepare.
Knowing that GRE scores are based on percentiles, I'm getting concerned that only the brightest, most knowledgable and prepared students are taking the October test and that I may get a much lower percentile in this test than I would if I took the November test.
As we recall, in previous years the December test was worthless and everyone had to take the November test and so everyone was compared to everyone else on a level field.
Can anyone comment on this? Does ETS somehow account for a statistical overall difference in the abilities of students taking different tests? Is this even a valid concern?
Thanks
