Well I did Find out that the classes you take before you get your GED are free but the test itself is $19.00 per section which is $95 total, which you have to pay in cash at the time you take the test. ( this is the amount for GA)
You will also have a Pre test to see how well you will do and that is $15. This is NOT FREE. There is no way getting around this part but the Pre test part is good so in case you don't like how your pretest comes out, then you can study and re take the pre test.
To find out Where you can get your GED, you'll need to call the The GED Testing Service provides a toll-free number accessible from Canada, Mexico and the United States: 1-800-626-9433 [(800) 62 MY GED].
