1st attempt at GMAT- 640

A little about myself. I am applying to a Masters in Accountancy for the upcoming Spring semester or Fall of '07. I have a good undergrad GPA- 3.62 Major- 3.91 in Finance, and have roughly 1.5 years of work experience. The issue of whether an MBA would be a wiser option has already been discussed and considered. For my career goals however, I need a CPA and Big 4 experience. An MS in Accountancy will require less time to complete and more specialized education towards these intermediary goals.

My preparation for the GMAT was really quite pathetic in retrospect. I studied off an on for roughly 1-2 months, sporadically logging 2-7 hours a week. I focused entirely on GMAT OG, only the quant section, and just ran through problems. Needless to say I think I could do substantially better on the exam. My question is will it hurt me for a career in Accounting? I do plan to go back and obtain an MBA before I open my own business, however as this endeavor is atleast 3-4 years down the road, my GMAT might be expired anyways. I am relatively confident that I can gain admittance to most any of the AACSB accredite Accounting program in the country. Do Accounting firms consider GMAT scores?

Thanks for the input.- Evan
