Search online for a GED class. These might be offered exclusively online or might come as a software download. The GED Academy and the GED Prep Bundle are two popular courses (see Resources).
Look for courses that meet specific requirements. Make sure the course reviews every subject covered on the GED and provides exercises and practice tests. Choose a course that provides one-on-one tutoring and allows you to work at your own pace. The course should have an accessible customer and technical support system. Also, take advantage of any free trials or demos the course might offer.
Check out the course with the Better Business Bureau. A course comparison Web site such as whichschool.us (see References) is also helpful. The Internet is filled with GED and high school diploma scams.
Sign up for the class. Most GED courses will require that you pay a fee in order to access its materials. Depending on the format, this can cost you anywhere from $65-$300.
