My stats are as follows:
Undergrad: BS Mechanical Engineering
GPA: 2.93
Work Experience: 5 years, mechanical and manufacturing engineering, at a globally-known corporation
GMAT: 610 (67%) - 34V (69%), 40Q (55%)
AWA: 6.0 (91%)
MBA of Interest: Marketing
Schools of Interest: mostly B-rank... BU, BC, Howard, Rutgers, Northeastern... maybe I'll add a "reach" school....
I'm not that unhappy with my GMAT score, given that my first assessment exam before studying was a 480 and I didn't think I'd get above a 550. I'm surprised my Quant. was so low; in fact, I'd rather have it the other way around! At first I was happy to get a perfect AWA score, but then I saw many boards and articles online saying that nobody cares about the AWA.

I really don't want to take it again and feel that I not only can write a killer application essay (or two, or three...) but maybe my work experience in such a demanding industry and field could speak for me, too.
Do I stand a chance getting in
anywhere?
