You take like 2 classes at once... maybe 3 at one point. You will take Disbursing the entire time, but you will also have Food Service, Postal, Supply Management, some IT classes and a few other things. It's been 2 years, so it's hard to remember. All tests are open pub, but don't think that makes it easy. The pubs are huge and hard to navigate.
Athens is a great town! I loved it. There is a lot to do, especailly if you like anything out-doors. There are a million apt in the town, because of the college. I would suggest going to the housing office and looking through their stuff. It is pretty updated and they can help you out.
The base is TINY... there is a small exchange, commisary, medical and NFCU on-base.
I'm not too sure about spouse employment. You will only be there about 7 months unless it is backed up and you get stashed.
