GED practice tests are the closest you can get to the real thing. They contain questions that are structured similarly to the ones you’d find in a real GED test. What’s great about practice tests is you’d get to know the correct answer after taking the test. This means you’re reviewing for the test and practicing and assessing your skills and knowledge at the same time. Some tests also include scores, which help predict your likelihood of passing or failing the exam.
