The GED has five sections: Language Arts (Reading); Language Arts (Writing); Social Studies; Science; and Mathematics.

The Reading Test consists of 40 multiple-choice questions on passages from fiction (75% of the exam) and non-fiction (25%). The fiction selections will include at least one from each of the following genres: poetry, drama, prose fiction before 1920, prose fiction from between 1920 and 1960, and prose fiction from after 1960. The non-fiction selections will come from two of the following genres: nonfiction prose, critical reviews of the visual or performing arts, or workplace and community documents.

The Writing Test has two parts. The first part of the exam consists of 50 multiple-choice questions in the following areas of content: organization (15%); sentence structure (30%); usage (30%); and mechanics (25%). The second part of the Writing Test consists of an assigned essay on some familiar subject. The scores from these two parts are combined to form a single Writing score.

The Social Studies Test has 50 multiple-choice questions in four content areas: geography (15%); history (US or Canada 25%, world 15%); civics and government (25%); and economics (20%).

The Science Test consists of 50 multiple-choice questions in these content areas: physics and chemistry (35%); life science (45%); and earth and space science (20%).

The Mathematics Test consists of two 25-question sections. In the first section, a calculator may be used. The Mathematics Test covers material from the following content areas: number operations and number sense (20 to 30%); measurement and geometry (20 to 30%); data analysis, statistics, and probability (20 to 30%); and algebra, functions, and patterns (20 to 30%). Some formulas are provided for the mathematics section. 

GED scores compare the test-taker’s performance in the five content areas with the performance of recent high school graduates. Individuals who take the GRE will be assigned a score between 200 and 800 in each of the content areas. These scores are not directly related to the number or percentage of correct answers in each section of the exam. In order to determine whether an individual has passed the exam, most states will look at the scores for each section and the average of all the scores. Although the minimum requirement varies from state to state, the GED Testing Service asserts that in order to pass an individual should get at least a 410 on each test as well as an average of 450.
