Most MBA schools allow 9 credits for transfer. I do know that Excelsior and APUS have very liberal policies, I recall APUS allowing up to 15 credits in transfer. Are you looking only at AACSB schools? Is cost an issue?
If cost is not an issue then your choices will be fairly large in number. I suggest reading through the MBA forum, especially the stcky threads. Business and MBA degrees
Could you expand on why you did not like the school? If it was this program I have only heard good about it (except for the cost): Online Master of Business Administration Degree - CSU Online Plus
The College of Business-West Texas A&M University can accept up to 12-hours of graduate transfer credits from another AACSB accredited program. West Texas A&M University: Online Master of Business Administration Degree
