Hi Carsondude!

The lack of an undergraduate business degree should not be a problem. Most MBA programs are designed for generalists and typically less than 1/3 of the class will have undergraduate business degrees. There are often, however, basic quantitative requirements. You should check to be sure your undergraduate math courses are adequate. If you don't have the required courses, most schools will simply require an extra math course either before entering or during the first year.

With a 650 plus GMAT you should be in good shape for the programs on your list. Your lack of business experience will be a problem since students in these schools average as much as five year's experience. However, part-time programs are often less rigid about work experience since they expect you to work while you are in school.

Your clear career goals and the fact that you are already working in the field will help. Sparkling, persuasive essays will be important in convincing the admissions reader that you understand what is involved in your target field and that you are committed to success.

Good luck and keep pushing toward that 650 plus GMAT.
