What Is on the GED Test? Subjects, Format, and Skills

What is on the GED test? The exam covers four subjects: Mathematical Reasoning, Reasoning Through Language Arts, Science, and Social Studies, delivered as four separate computer-based tests. Each subject has its own time limit, question styles, and passing score, so understanding the structure before you register saves both money and study hours.

In this guide from GED Prep, you will learn what the GED test consists of, the question formats to expect, how scoring works, and how to prepare for each section with confidence.

What is on the GED test? A quick overview

The GED test is a high school equivalency exam made up of four separate subject tests: Mathematical Reasoning, Reasoning Through Language Arts (RLA), Science, and Social Studies. Together, these exams measure whether you have the same academic knowledge and reasoning skills expected of a graduating U.S. high school senior. Unlike many traditional school exams, the GED emphasizes applying knowledge to real-world situations rather than memorizing facts, formulas, or historical dates.

Each subject is taken independently, allowing you to schedule the tests in any order and at your own pace. Many candidates complete one subject at a time, while others finish two subjects in a single testing session depending on their confidence and study schedule. Because every subject receives its own score, passing one exam means you never have to retake it again, even if you need to retake another subject later.

Although the four subjects cover different academic content, they share several important characteristics:

All tests are computer-based, so you'll answer questions using an on-screen interface rather than paper.
Questions are designed to assess critical thinking, problem-solving, and reasoning, not simple memorization.
You'll regularly work with reading passages, charts, graphs, tables, diagrams, maps, and real-world documents to answer questions.
Several technology-enhanced question types appear throughout the exam, including drag-and-drop, fill-in-the-blank, drop-down, and hot spot questions.
Every subject is scored on the same 100-200 scale, with 145 required to pass each individual test.

The table below summarizes what each GED subject covers and how long you'll have to complete it.

GED subject	Time limit	What you'll be tested on
Mathematical Reasoning	115 minutes	Quantitative reasoning, algebra, geometry, statistics, data analysis, and real-world math problem solving. The first five questions are completed without a calculator, while the remaining questions allow the on-screen TI-30XS calculator.
Reasoning Through Language Arts (RLA)	150 minutes	Reading comprehension, grammar and language, evaluating arguments, and one 45-minute Extended Response essay based on two opposing passages.
Social Studies	70 minutes	Civics and Government (50%), U.S. History (20%), Economics (15%), and Geography and the World (15%), with an emphasis on interpreting historical documents, maps, graphs, and political cartoons.
Science	90 minutes	Scientific reasoning using Life Science (40%), Physical Science (40%), and Earth and Space Science (20%) through experiments, graphs, tables, and evidence-based questions.

One important thing to remember is that every GED subject integrates reading skills, even those that are not traditionally considered language-based. For example, Math problems are often presented as real-life scenarios, Science questions frequently require interpreting experiments or research summaries, and Social Studies relies heavily on analyzing historical documents and visual sources. Strong reading comprehension therefore benefits you across all four sections, not just the Language Arts test.

Another helpful point is that the GED is designed to measure reasoning, not recall. Rather than asking, "What year did this event happen?" or "Define this scientific term," the exam is more likely to ask you to interpret evidence, compare arguments, identify patterns in data, solve practical problems, or draw logical conclusions based on the information provided. This means developing critical thinking skills is often more valuable than trying to memorize large amounts of information.

If you're unsure which subject needs the most preparation, the smartest place to start is with a GED diagnostic test. A diagnostic exam quickly identifies your strongest and weakest areas, helping you prioritize your study time and create a more efficient preparation plan before moving on to subject-specific practice tests.

What subjects are on the GED test?

The GED test is divided into four separate subject exams: Mathematical Reasoning, Reasoning Through Language Arts (RLA), Social Studies, and Science. Each subject measures a different set of academic skills, but all four focus on applying knowledge to real-world situations rather than memorizing facts. While every test has its own content, time limit, and question styles, they all require strong reading comprehension, critical thinking, and problem-solving abilities. Understanding what each subject covers will help you build a more focused study plan, prioritize the areas that need the most attention, and prepare more efficiently for the GED exam.

Mathematical Reasoning

The GED Mathematical Reasoning test takes 115 minutes and covers four main areas: basic math, geometry, basic algebra, and graphs and functions. The test includes a short break between its two parts, and a calculator is available for most questions. You also have access to a math formula sheet and calculator reference sheet.

The math content can generally be divided into two main skill areas.

Quantitative problem solving includes skills such as:

Working with whole numbers, fractions, and decimals
Ratios, rates, proportions, and percentages
Exponents and roots
Measurement and unit conversions
Perimeter, area, surface area, and volume
Mean, median, and other basic data concepts
Solving real-world mathematical problems

Approximately 45% of the Mathematical Reasoning test focuses on quantitative problem solving.

Algebraic problem solving includes:

Simplifying and evaluating expressions
Solving equations and inequalities
Writing equations from word problems
Graphing equations
Understanding slope and rate of change
Working with functions
Solving systems of equations
Basic polynomial and quadratic problems

Algebraic problem solving makes up approximately 55% of the test, so algebra is an especially important area to study.

You do not need to memorize every mathematical formula. A formula sheet is provided during the test, but you still need to know which formula to use and how to apply it correctly. The on-screen TI-30XS calculator is available for most questions, while some questions must be completed without a calculator.

If you want to measure your current level before studying, take a GED Mathematical Reasoning practice test to identify your strongest skills and the topics that need additional review. Once you're consistently performing well on topic-based questions, challenge yourself with a full-length practice test to build stamina and experience the real exam under timed conditions.

Reasoning Through Language Arts

The GED Reasoning Through Language Arts test, often called GED RLA, is the longest subject test at 150 minutes. It measures your ability to understand written information, analyze arguments, use standard English correctly, and write an evidence-based response. The test includes a 10-minute break and 45 minutes for the extended-response essay.

The three main areas tested are Reading for Meaning, Identifying and Creating Arguments, and Grammar and Language.

For reading comprehension, you may need to:

Identify a passage's main idea
Find supporting details
Make logical inferences
Determine the author's purpose or point of view
Understand vocabulary from context
Analyze relationships between ideas
Compare information from different texts
Distinguish claims from supporting evidence

Most of the passages are informational rather than literary, so you should be comfortable reading nonfiction texts such as articles, workplace documents, historical passages, and other informational materials.

Another major part of the RLA test is argument analysis. Questions may ask you to identify an author's claim, evaluate the evidence used to support it, or compare two opposing arguments. The goal is not to decide whether you personally agree with an author. Instead, you need to determine which argument is better supported by the information provided.

The test also covers grammar and editing skills, including:

Sentence structure
Subject-verb agreement
Pronoun use
Verb tense
Punctuation
Capitalization
Word choice
Paragraph organization
Transitional words and phrases

The RLA test also includes one extended-response essay. You are given two passages presenting different arguments and have 45 minutes to write a response explaining which argument is better supported. A strong response uses specific evidence from the passages and clearly explains why that evidence makes one argument stronger.

Once you're familiar with these skill areas, take a GED Reasoning Through Language Arts practice test to identify your current level, improve reading speed, and become comfortable answering passage-based questions under timed conditions. After improving your reading and writing skills, complete a full-length practice test to practice managing the 150-minute exam and the Extended Response under realistic timing.

Social Studies

The GED Social Studies test takes 70 minutes and has no scheduled break. It covers civics and government, U.S. history, economics, and geography and the world. However, the test is not mainly about memorizing historical dates, names, or isolated facts. Instead, it measures your ability to read social studies information, analyze historical arguments, and interpret numbers and graphs.

The approximate content distribution is:

Civics and government: 50%
U.S. history: 20%
Economics: 15%
Geography and the world: 15%

Civics and government is the largest content area. Topics may involve:

The U.S. Constitution
The branches of government
Checks and balances
Individual rights and responsibilities
Elections and voting
Public policy
Civil rights and liberties

U.S. history questions may cover major periods and developments such as the founding of the United States, the Civil War, Reconstruction, industrialization, immigration, and major social and political movements.

Economics questions can involve concepts such as supply and demand, markets, labor, economic choices, and government economic policies. Geography questions may use maps, demographic information, migration patterns, natural resources, or global relationships.

More importantly, Social Studies questions may require you to:

Read historical documents
Compare different viewpoints
Identify claims and evidence
Recognize cause-and-effect relationships
Interpret maps and timelines
Analyze political cartoons
Read charts, graphs, and tables
Draw conclusions from the information provided

An on-screen calculator and calculator reference sheet are also available for questions involving numerical information.

To improve these skills, complete a GED Social Studies practice test and learn how to analyze authentic historical sources under realistic testing conditions. When you're comfortable analyzing historical documents and data, move on to a full-length practice test to simulate the pace and difficulty of the actual exam.

Science

The GED Science test takes 90 minutes and has no scheduled break. Rather than requiring you to memorize large amounts of scientific information, it focuses heavily on your ability to understand scientific concepts, evaluate experiments, interpret data, and draw evidence-based conclusions.

The science content is divided into three main areas:

Life science: 40%
Physical science: 40%
Earth and space science: 20%

Life science may include topics such as:

Cells and living organisms
Human body systems and health
Genetics and heredity
Evolution
Ecosystems
Food chains and energy flow

Physical science may cover:

Matter and its properties
Chemical reactions
Energy
Force and motion
Work
Electricity
Heat and waves

Earth and space science may include:

Earth's systems
Weather and climate
Natural resources
Geological processes
The solar system
Relationships between Earth and living organisms

Scientific reasoning is especially important on this part of the GED. You may be given an experiment, graph, diagram, or data table and asked to determine what the results mean.

Skills you should be prepared to use include:

Identifying a hypothesis
Recognizing independent and dependent variables
Identifying control and experimental groups
Evaluating experimental procedures
Interpreting graphs and tables
Comparing data
Finding patterns and trends
Determining whether evidence supports a conclusion

For example, a question might describe an experiment in which plants receive different amounts of water and ask you to identify the independent variable or determine whether the results support the original hypothesis.

You do not need to memorize scientific formulas. When a calculation is required, the information you need is generally provided in the question. An on-screen calculator is also available during the Science test.

After reviewing these content areas, strengthen your scientific reasoning with a GED Science practice test to become comfortable interpreting experiments, graphs, and evidence under timed exam conditions. Before scheduling your official exam, take a full-length practice test to build confidence interpreting experiments, charts, and evidence within the official time limit.

Overall, knowing what test subjects are on the GED test is only the first step. Each section combines subject knowledge with reasoning skills, so effective preparation should include both reviewing important concepts and practicing GED-style questions. Understanding the format, time limit, and key skills for each subject can help you focus your study time where you need it most.

What types of questions are on the GED test?

The GED is a computer-based exam, so you'll encounter more than traditional multiple-choice questions. While multiple-choice remains the most common format, every subject also includes technology-enhanced questions that measure how well you can apply knowledge, analyze information, and interact with digital content. Becoming familiar with each format before test day helps you work more efficiently and avoid losing time simply because the interface feels unfamiliar.

Multiple choice

Multiple-choice questions make up the majority of the GED test across all four subjects. Each question provides four answer choices, but only one is correct. Although the format looks familiar, the questions often require reasoning rather than simple recall. Instead of asking for isolated facts, they usually present a passage, graph, chart, table, or real-world scenario that you must analyze before selecting the best answer.

Across the four subjects, multiple-choice questions may ask you to:

Interpret graphs, tables, and charts.
Analyze reading passages and identify the main idea.
Solve mathematical problems using algebra or quantitative reasoning.
Evaluate scientific evidence and experimental results.
Draw conclusions from historical documents or political cartoons.

The best strategy is to eliminate clearly incorrect answers first, then compare the remaining options carefully. Since there is no penalty for guessing, never leave a multiple-choice question unanswered.

Drag and drop

Drag-and-drop questions require you to move words, numbers, labels, or phrases into the correct locations on the screen. Rather than selecting an answer, you actively organize information to demonstrate your understanding.

Depending on the subject, you may be asked to:

Match vocabulary with definitions.
Place events into chronological order.
Complete a mathematical equation by dragging numbers or expressions.
Label parts of a diagram or graph.
Organize evidence into the correct categories.

Because this format is interactive, accuracy matters just as much as content knowledge. Always double-check that every item has been placed in the intended location before moving to the next question.

Fill in the blank

Fill-in-the-blank questions require you to type your own answer instead of choosing from a list of options. These questions appear most frequently in Mathematical Reasoning but may also appear in other subjects when a short numerical or text response is required.

You may be asked to:

Calculate a mathematical answer.
Complete an equation.
Enter a missing number from a graph or table.
Type a short word or phrase based on a reading passage.

Unlike multiple-choice questions, there are no answer choices to guide your thinking or help you estimate the correct response. For this reason, fill-in-the-blank questions require careful calculations and attention to detail. Before submitting your answer, verify your work and make sure you entered the correct number, decimal, or fraction.

Drop-down

Drop-down questions ask you to select the correct answer from one or more menus embedded within a sentence, paragraph, table, or diagram. These questions are especially common in the Reasoning Through Language Arts test, where they assess grammar, sentence structure, organization, and word choice.

You may need to:

Choose the correct grammar or punctuation.
Select the best transition between ideas.
Complete a sentence using the most appropriate word or phrase.
Identify the strongest supporting evidence within a passage.

Rather than testing isolated grammar rules, these questions evaluate whether you can improve writing within its original context. Always read the entire sentence or paragraph before making your selection to ensure your answer fits the overall meaning.

Hot spot

Hot spot questions require you to click directly on a specific location within an image, graph, map, number line, chart, or diagram. Instead of selecting text, you identify the correct visual element that answers the question.

Examples include:

Clicking a point on a coordinate graph.
Selecting the correct location on a map.
Identifying a section of a scientific diagram.
Choosing the correct value on a number line.
Locating evidence within a visual display.

Many students lose points by clicking too quickly without carefully examining labels, scales, or axes. Spend a few extra seconds studying the visual before selecting your answer, especially when several points appear close together.

Extended Response

The Extended Response is the only essay on the GED test and appears exclusively in the Reasoning Through Language Arts (RLA) exam. You have 45 minutes to read two opposing passages, compare the quality of their arguments, and write an evidence-based essay explaining which argument is better supported.

Your essay is evaluated on three major areas:

Creating a clear thesis that answers the prompt.
Using relevant evidence from both passages.
Organizing ideas logically while demonstrating proper grammar and language conventions.

The essay does not measure your personal opinion or creative writing ability. Instead, scorers evaluate how effectively you analyze arguments and support your conclusions with evidence from the provided texts. A well-organized essay with clear evidence typically earns a stronger score than a longer essay filled with unsupported opinions.

Successful test-takers practice writing under timed conditions before exam day so that planning, organizing, and citing evidence become natural parts of their writing process.
