Should one consider studying GRE CR as well in order to improve their GMAT CR?
There aren't any fundamental logical differences between the two. (This is in contrast to the LSAT, which has question types that ask for a fundamentally different type of reasoning than the GMAT does: for instance, the LSAT sometimes asks about sufficient assumptions, as well as necessary assumptions.) That said, I don't think that GRE Verbal problems are any better than GMAT ones, for study purposes or otherwise. And in my experience, GRE Verbal problems (including CR) sometimes aren't as well-written or logically sound as GMAT ones are.
So I guess my answer is 'there's no reason not to, but I don't think it would be of any specific benefit.'
Would you prefer GRE CR and RC questions for GMAT CR & RC prep to third part material after Ive exhausted about 7k original retired GMAT questions?
So here is the order I'm thinking: GMAC Questions --> ETS GRE Questions --> 3rd Party Prep Co. Questions --> LSAT
