What is on the GED test? The exam covers four main subjects: Mathematical Reasoning, Reasoning Through Language Arts, Social Studies, and Science. Each section tests both subject knowledge and your ability to analyze information, solve problems, and apply what you know. This guide explains the topics covered in each GED subject, the types of questions you may encounter, and how the GED test is scored.
What is on the GED test? A quick overview
The GED test includes four separate subject exams: Mathematical Reasoning, Reasoning Through Language Arts, Social Studies, and Science. Each section measures high-school-level knowledge as well as your ability to analyze information, solve problems, interpret data, and apply what you know in practical situations. You can take the four subjects separately rather than completing the entire GED in one sitting.
Here is a quick look at what is on the GED test:
|

What is covers |
Time limit |
|
Mathematical Reasoning |
Basic math, geometry, algebra, graphs, and functions |
115 minutes |
|
Reasoning Through Language Arts |
Reading comprehension, argument analysis, grammar, and writing |
150 minutes |
|
Social Studies |
Civics, U.S. history, economics, geography, and data interpretation |
70 minutes |
|
Science |

90 minutes |
Together, the four subject tests provide about 7 hours and 5 minutes of testing time. The Language Arts section is the longest and includes a 45-minute written essay, while Math, Science, and Social Studies include questions that may require calculations or data interpretation.
The GED is not simply a test of memorization. For example, Social Studies emphasizes analyzing historical information and graphs, while Science focuses heavily on interpreting experiments and scientific evidence. Math tests both quantitative and algebraic problem-solving, and Language Arts measures how well you understand texts, evaluate arguments, and communicate ideas in writing.
Understanding this overall structure gives you a clearer idea of what to expect before looking more closely at each GED subject.
What subjects are on the GED test?
The GED test consists of four subject areas: Mathematical Reasoning, Reasoning Through Language Arts, Social Studies, and Science. Each subject is taken as a separate exam, so you can complete them one at a time instead of taking all four on the same day.
Although each section focuses on a different academic area, the GED is not simply a test of memorized facts. You will also need to solve problems, interpret information, analyze evidence, and apply what you know to real-world situations.
Mathematical Reasoning
The Mathematical Reasoning test covers basic math, geometry, algebra, graphs, and functions. It takes 115 minutes and includes both calculator and non-calculator questions. A math formula sheet and calculator reference sheet are provided during the exam, and an on-screen calculator is available for most questions.
The main skills tested include:
-
Working with whole numbers, fractions, decimals, and percentages.
-
Ratios, rates, and proportions
-
Exponents and roots
-
Measurement and unit conversions
-
Perimeter, area, surface area, and volume
-
Interpreting tables, graphs, and numerical data
-
Simplifying algebraic expressions
-
Solving equations and inequalities
-
Understanding slope and linear relationships
-
Working with functions and coordinate graphs
-
Applying math to real-life word problems
The Math test emphasizes two formats: quantitative problem solving and algebraic reasoning. Instead of simply performing calculations, many questions ask you to determine which mathematical method should be used to solve a problem.
You do not have to memorize every formula, but you should understand when and how to use the formulas provided during the test.
Before test day, taking a GED Math practice test can help you see which areas need the most review. It is especially useful for checking your algebra skills, calculator use, and ability to solve multi-step word problems under time pressure.
Reasoning Through Language Arts
The Reasoning Through Language Arts (RLA) test measures reading comprehension, writing, grammar, and your ability to analyze arguments. It lasts 150 minutes, making it the longest of the four GED subject tests. It also includes a 45-minute extended-response essay.
The main areas tested include:
-
Reading for meaning
-
Identifying and analyzing arguments
-
Grammar and language
-
Writing an evidence-based response
For the reading portion, you may need to:
-
Identify the main idea of a passage
-
Find supporting details
-
Make logical inferences
-
Determine an author’s purpose or point of view
-
Understand vocabulary from context
-
Analyze vocabulary from context
-
Analyze relationships between ideas
-
Compare information from different texts
-
Distinguish claims from supporting evidence
You will also need to analyze arguments. This can involve identifying an author’s main claim, evaluating the evidence used to support it, comparing different arguments, and recognizing weak or unsupported reasoning.
Grammar questions may test:
-
Sentence structure
-
Subject-verb agreement
-
Pronoun use
-
Verb tense
-
Punctuation
-
Capitalization
-
Word choice
-
Paragraph organization
-
Transitional words and phrases
The RLA test also includes an extended response. You will read two passages presenting different arguments and explain which argument is better supported by evidence. The goal is not simply to state your opinion, but to support your analysis with details from the texts.
A GED Language Arts practice test can help you become more comfortable with longer passages, argument-based questions, and grammar tasks. You can also use timed practice to improve reading speed and make sure you leave enough time for the extended response.
Social Studies
The Social Studies test takes 70 minutes and focuses on civics and government, U.S. history, economics, and geography. However, the test is not mainly about memorizing historical dates or names. Instead, it measures your ability to understand documents, interpret data, analyze arguments, and draw conclusions.
The main content areas include:
-
Civics and government
-
United States history
-
Economics
-
Geography and the world
Civics and government makes up the largest portion of the test. Topics may include the U.S. Constitution, branches of government, checks and balances, elections, individual rights, and public policy.
U.S. history questions may cover major events and developments such as the founding of the United States, the Civil War, Reconstruction, industrialization, immigration, and major political and social movements.
Economics and geography questions may involve supply and demand, markets, population, migration, natural resources, maps, and demographic information.
More importantly, you may need 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
Because Social Studies depends heavily on source analysis, a GED Social Studies practice test is a good way to practice working with historical passages, maps, graphs, and charts. It can also help you get used to answering questions based on evidence rather than relying only on memorized facts.
Science
The Science test takes 90 minutes and focuses on scientific reasoning as well as knowledge from life science, physical science, and Earth and space science.
The three main content areas are:
-
Life science
-
Physical science
-
Earth and space science
Life science may include:
-
Cells and living organisms
-

A major part of the Science test is understanding experiments and scientific data. You may be given a graph, table, diagram, or experiment description and asked to determine what the results show.
Important scientific reasoning skills include:
-
Identifying a hypothesis
-
Recognizing independent and dependent variables
-
Identifying control and experimental groups
-
Understanding charts, diagrams, and graphs
-
Comparing data
-
Recognizing patterns and trends
-
Drawing conclusions from evidence
-
Determining whether results support a hypothesis
You do not need advanced scientific knowledge to answer every question. In many cases, the information needed is already provided in the passage, graph, or experiment.
Taking a GED Science practice test can help you practice interpreting experiments, identifying variables, and reading scientific graphs. It is also useful for learning how to find the information you need quickly instead of trying to memorize every science fact.
GED test format and scoring
Knowing the GED test format can help you understand what to expect on test day. The exam uses several question types across its four subjects, and each subject receives its own score on a scale from 100 to 200. You must meet the required score on all four subjects to earn your GED credential.
Types of questions on the GED test
The GED is primarily computer-based and includes more than traditional multiple-choice questions. Depending on the subject, you may see:
-
Multiple-choice questions: Choose the correct answer from the available options
-
Fill-in-the-blank questions: Type a word, number, or mathematical answer into the provided field.
-
Drag-and-drop questions: Move an answer, label, or piece of information to the correct location.
-
Drop-down questions: Select the correct answer from a menu within a sentence or passage.
-
Select-an-area questions: Click the correct location on an image, graph, diagram, or other visual.
-
Extended Response: The Reasoning Through Language Arts test includes a written essay in which you analyze arguments and support your response with evidence.
GED score range
Each of the four GED subject tests is scored separately on a scale from 100 to 200. The GED score range is divided into four performance levels:
|
GED score range |
Score level |
What it means |
|
100-144 |
Below Passing |
You have not yet passed that subject |
|
145-164 |
GED Passing |
You have met the minimum passing standard |
|
165-174 |
GED College Ready |
You have demonstrated college-readiness skills |
|
175-200 |
GED College Ready + Credit |
You may qualify for college credit at participating institutions |
The GED passing score is 145 for each subject. This means you must earn at least 145 in Mathematical Reasoning, Reasoning Through Language Arts, Social Studies, and Science individually. Your four scores are not averaged, so a high score in one subject cannot compensate for a score below 145 in another.
If you do not reach 145 on one subject, you generally only need to retake that subject rather than repeating the tests you have already passed. Understanding both the question formats and the GED score range can help you set clear goals and prepare more effectively for each section of the exam.
FAQs
1. What is the hardest subject on the GED test?
For many test-takers, Mathematical Reasoning is the most difficult GED subject because it focuses heavily on algebra and multi-step problem solving.
