Enroll in a GED preparation class. Check with adult education centers, community colleges and any other educational resources in your area to see who offers GED preparation classes. This will help determine in what subjects you need the most help. There may be a small fee but some institutions and organizations offer the classes for free.
Purchase a GED study guide. Most bookstores offer study guides to help test-takers prepare. There are many different types of study guides that offer help in particular subjects such as math or English. Also, you will find many that come with CDs, which allow you to listen along as someone teaches you the information.
Study hard. Devote plenty of time to studying and be sure that there are minimal distractions. Study at least one hour a day and have someone test your knowledge on the information in the study guide. Don't cram the night before your test or push yourself too hard. Pace yourself, instead, so you can best understand and comprehend the information.
Join a GED study group. These provide a great deal of help to those who have been out of school for long periods of time. Get together with others who share your same goal of passing the GED; they will provide you with study techniques as well as great motivation. Also, working with a group will allow you to bounce questions and answers off each other. Stay focused; when working with a group of people, you can sometimes get off task. Remember that your common goal is to pass the exam.
