Windmill, I was in your boat a year and a half ago. I had a Finance degree and had been out of school for 6-7yrs...been selling real estate. I had taken Business Law and Intermediate 1, both of which counted towards my 30hrs of upper-level credit. I went back to school and obtained the remaining hours to hit the 30 required of upper-level accounting. As well I now have 150 total.
I began studying for the CPA exam in mid April once my internship ended. I bought Yaeger and passed FAR, REG and BEC. Failed AUD the first time, and just took it again last week...hopefully passed it this go round.
As some have said you will be fine in BEC. It is a lot of financial ratios that you used in Finance, and several other "general business" topics.
First things first, you need to see what your state requires to sit for the exam, and then usually what it requires to get licensed once you pass the exam, as I know in GA these two are different. Allow yourself about 2mos to study for FAR, and probably 1.5mos for REG and AUD, and BEC can probably be done in a month. I have definitely been in your place. I think you are making a wise choice. This process from start to finish seems like it takes forever, but I personally cannot be happier with the choice I made. I am sure you will be as well.
FAR - 82
REG - 84
BEC - 88
AUD - 68, awaiting score from retake.
