Well, PhD econ programs almost universally require the GRE. GMAT is generally allowed for finance programs, which I'm not applying to.
I'm not really sure what you mean regarding verbal, though I've always found Sentence Completions to be easy. Quantitative wasn't bad as a whole, but I'm a math major and did a lot of prep from the Nova Math Bible and the 800score.com CAT's. I just fudged my time management on a quant. comparision problem which led me to the pressure cooker situation in my OP. Ending up with the 800 was the last thing on my mind when I clicked to see my scores after the test. I probably could've done better on AWA, specifically the issue essay (I kinda ignored studying for the AWA), but I think I rocked the argument analysis essay.
