I'm not sure about the MCAT/GMAT/LSAT but the GRE is a pretty bad indicator. For example, everyone who goes to grad school for computer science or engineering gets minimum a 750 on the quantitative section. The math only tests high school level ability.

While I don't have any links, I think that there are many studies showing that SAT/GRE type scores don't mean very much.

I remember taking the GRE, I got 99 percentiles on quantitative and logical reasoning...and like 69 percentile on verbal. The verbal part was basically a vocabulary test.
