GRE (taken in 2006): 700 M, 600 V, 6.0/6.0 W. I think that was like 75% math, 90% verbal, and 95% writing. I took this thing cold - my math could have been higher, the verbal was a monster. Tons of words that I never saw before. GMAT: 720, 6.0 W. Spent maybe 4 days prepping sentence correction. Took one practice to get format down. Note: I took the LSAT, which prepped me on verbal hardcore (the reading comp and analytical questions on the GMAT are a joke compared to LSAT) so my verbal was already prepped. Without the LSAT I would have needed to spend a few weeks prepping verbal. Math wasn't bad but I should have done some prep as the questions are tricky (but not math tricky, like LSAT games tricky). Prepping for 2-3 months for the GMAT should get you a 700+ easily if you are decent at standardized testing. Similarly on the GRE, a 1400+ should be achievable in a similar time period, as long as you pay attention to memorization of vocab (assuming the exam hasn't changed in the last 5 years) and just use a decent prep book. Manhattan Prep for the GMAT is best, I know that for sure. For the GRE I don't know. I didn't prep. :-/
