I took my salesperson's as well as broker's class through GAMLS (atlantarealestateschool.com). However, I did the software course.
I was really impressed with their cram course. It was extremely beneficial and covered a lot of stuff that ended up being on the test.
Compare schools. Barney Fletcher and the Georgia Institute of Real Estate (Run by the Atlanta Board of Realtors) are good sources as well.
