Dear dikku07,
In my opinion, I think it will be difficult to receive an offer of admission from any of the schools on your list with a GMAT score less than a 650. While it will help if your GPA comes back high (>3.6 on US 4.0 scale), the schools will still want to see a GMAT score that confirms you can succeed in the business school classroom. Similarly, you will need to have a solid rationale for why you want a MBA and how your past experiences fit in with your future career goals. I would suggest doing some research on schools with GMAT averages in the 550-650 range and then see how you score on the GMAT to determine where to apply.
Good luck,
Lisa
