Based on the information provided you sound like a strong competitior, outside of the GMAT score.
90% of admits at those schools score around 660, so off-the-cuff, I'd say that's a pretty good low-end target.
Thank you for the feedback... I realize the GMAT score is well.... a bit of a blemish. I should be able to recover from it, but as I stated it has ratlled my confidence.
Anyway thank you... I wanted to make sure my background was strong enough to even get into those schools before putting the time into the GMAT again....
