Congrats on the great score,
nbock! As usual, I agree with
bb that the retake decision ultimately depends on a whole lot of other stuff in your profile. We've all seen plenty of folks with weak quant scores do fine in admissions, as long as they have other ways of showing MBA programs that they can handle the academic work.
I'll come at this from a different direction, though: you have an incredible verbal score, so if you can get the quant up in the ~65th percentile range, you'll be set up for a composite in the mid-700s, and that *might* really change things for you in terms of your target schools. I'm convinced that nearly anybody can get to a 47 in quant with enough work and pain. I'm not saying that it's always worth it, but it's worth thinking about.
And if you could please bottle up whatever you're doing on the verbal and send it over to us here in the verbal forum, we'd all be eternally grateful.
Congratulations again!
