Obviously, MBA admission is based upon more than a few metrics. However, the applicant pool has become ultra-competitive lately and GMAT scores seem to be trending up. From a pure numbers standpoint, you would be competitive in the top 20 - 40 range. But there are many factors to consider ie. your professional history, your goals, international experience, and anything that makes you stand out as a unique and interesting candidate. If you can pull together a strong application with well written LORs and thoughtful essays then you might consider higher ranked programs as well.
