What the GED is (and who takes it)
The GED is a high school equivalency test. Pass all four subject tests and you earn a high school equivalency credential, which employers, job-training programs, and colleges widely accept in place of a traditional diploma.
It's built for adults who didn't finish high school, whether you left last year or 30 years ago. Age limits and other requirements vary by state; when you create your account on GED.com, it applies your state's rules.
A few things that surprise people:
- It's four separate tests, not one. You don't have to take them all at once. Schedule, take, and pass each subject on its own, in any order, at your own pace.
- You only pass each subject once. Pass Science in March and it stays passed while you work on Math.
- It's a reasoning test, not a memorization test. You won't be asked to recite capitals or dates. Science and Social Studies hand you the passage, chart, or data, and your job is to read it and reason.
- Scoring is fast. GED.com lists same-day scoring and a personalized score report for both test-center and online testing.
Some states offer a different high school equivalency exam instead of, or alongside, the GED. If you're not sure which one your state uses, check GED.com or your state's adult education office.
GED test format: the four subjects
Here's what each subject test looks like. Each time includes a couple of minutes for instructions and a final review.
| Subject | Time | What's on it | Worth knowing |
|---|---|---|---|
| Mathematical Reasoning | 115 min, with a 3-minute break between parts | Basic math, geometry, basic algebra, graphs and functions | Part 1 is no-calculator; Part 2 has an on-screen calculator. Formula sheet and calculator reference sheet provided |
| Reasoning Through Language Arts (RLA) | 150 min, including a 10-minute break between Parts 2 and 3 | Reading for meaning, identifying and creating arguments, grammar and language | Three sections, including a 45-minute extended response (essay) |
| Science | 90 min, no break | Life, physical, and Earth and space science; reading for meaning, designing and interpreting experiments, using numbers and graphics | On-screen calculator available; you're given the information you need, so no formulas to memorize |
| Social Studies | 70 min, no break | Civics and government, U.S. history, economics, geography; reading for meaning, analyzing historical events and arguments, using numbers and graphs | On-screen calculator available; lots of historical excerpts, graphs, and charts |
That's about 7 hours of testing in total, but you'll never sit for all of it in one day unless you choose to. At a test center you may bring your own TI-30XS calculator for the subjects that allow one.
Question types
Every subject is on a computer and mixes several formats:
- Multiple choice
- Drop-down menus inside a sentence or passage
- Fill-in-the-blank, where you type a number or a short answer (Math, Science, Social Studies)
- Drag-and-drop, where you move items into place, such as ordering steps or building an expression
- Select an area, where you click a spot on a graph, diagram, or map
RLA also includes one typed essay, the extended response. The other three subjects have no essay.
How GED scoring works
Each subject is scored on a scale that runs from 100 up to 200. It's a scaled score, not a percent correct.
| Score | Level | What it means |
|---|---|---|
| 100โ144 | Below passing | Retake the subject |
| 145โ164 | GED Passing Score | Counts toward your credential |
| 165โ174 | GED College Ready | Shows readiness for college coursework; you may qualify for waivers from placement testing or developmental education requirements |
| 175โ200 | GED College Ready + Credit | Shows skills that could qualify for up to 10 college credit hours; ask your college how it applies |
You need at least 145 on every subject. A 190 in Science doesn't make up for a 140 in Math; each test stands on its own.
You get your score the same day, along with a personalized score report. If you need a retake, the report's breakdown of what to study is the most useful guide you'll get.
Cost and how to register
Registration runs through GED.com. Create a free account and it checks your state's requirements, shows test centers and online options, and lets you schedule and pay one subject at a time.
Cost varies by state, and you pay per subject. Choose your state on GED.com's price and rules page to see current fees and requirements. Testing at a center comes with discounted retakes; see the retake section below.
Before you pay full price, check two things. Some employers cover GED prep and testing for their employees through a program called GEDWorks. And local adult education programs may offer free GED classes; GED.com has a class finder.
Taking the GED online
You can take the GED from home with a live online proctor, but there's a gate: you need a green ("likely to pass") score on the official GED Ready practice test for that subject, and you have to schedule the online test within 60 days of scoring green.
What you'll need:
- A computer with a webcam and a reliable internet connection. You'll run a system test first to check compatibility.
- A private room with four walls and a closed door. No one else is allowed in the room once the exam starts.
- A government-issued photo ID for check-in.
Not every state offers online testing, and some states have their own age rules for it. Retakes also work differently online: you don't get as many immediate attempts as you do at a test center, which is part of why the GED Ready requirement exists. Check the GED online testing page for your state.
Test center or online? If your home is noisy or your internet is shaky, a test center removes a lot of risk, and it comes with more generous retake rules. If unfamiliar places make you anxious and you have a quiet room, online can be the better experience.
If you donโt pass: retakes
Missing 145 on a subject isn't the end of anything. At a test center, you can retake a failed subject twice with no waiting period between attempts. If you fail the third attempt or any later one, you have to wait 60 days before trying again.
- Discounted retakes: GED Testing Service waives its portion of the fee on retakes of failed subjects, which applies to two retests taken within 12 months of your first full-price attempt. States and test centers can still charge their own fees.
- Online retakes: the rules vary by state, so check your state's policy.
- Retaking a subject you passed to raise your score is allowed in most states with approval from GED Testing Service.
Details are on GED.com's retake FAQ. Before you rebook, use your score report to target the skills that cost you points, retake GED Ready, and book the real test again when you're green.
How to prep: a realistic plan
How long you need depends entirely on where you're starting. Someone who left school in 11th grade last year and someone who hasn't done algebra in 25 years are running different races. This plan works for both:
- Get a baseline. Take a full-length practice test in each subject, such as our free GED practice tests. Don't study first. You want an honest read. We have two tests per subject, so you can save the second one to measure your progress.
- Start with your strongest subject. Passing one test quickly builds momentum and gets you comfortable with the testing software.
- Study in short, regular sessions. 45 to 60 minutes, four or five days a week, beats a six-hour Saturday cram. Work from your mistakes, not from page 1 of a textbook.
- Check readiness with GED Ready. It's timed and half the length of the real test. When you score green, book the real test while the material is fresh.
- Give your weakest subject its own block. If that's Math, work through the GED Math guide. If it's reading or writing, start with the GED RLA guide.
Rough timelines, as a starting point: if your baseline is already close to passing, a few weeks per subject is often enough. If it's been years since you were in a classroom, plan on one to three months per subject. Your practice results are the real guide; adjust as you go.
Whatโs changed recently
As of our September 2026 check, GED.com's test pages describe the same four-subject structure covered here, and we found no announced format changes. The GED's core pieces (four subjects, the 145 passing score, and the College Ready levels) have been stable for years.
The part that has grown is online testing, which comes with its own rules: a recent green GED Ready score, a private room, and state-specific retake limits. State policies, including prices, age requirements, and online availability, change more often than the test itself, so confirm the details for your state on GED.com before you pay.

ReadFrequently asked questions
What score do you need to pass the GED?
145 on each of the four subjects. There's no averaging: every subject needs its own 145. Scores of 165 and up earn the GED College Ready designation, and 175 and up earn College Ready + Credit.
How long is the GED test?
About 7 hours in total: Math is 115 minutes, RLA is 150 minutes (including a 10-minute break), Science is 90 minutes, and Social Studies is 70 minutes. You schedule each subject separately, so you can spread them over weeks or months.
Can I take the GED online?
Yes, if your state offers it and you've scored green ("likely to pass") on the official GED Ready practice test for that subject within the last 60 days. You'll need a computer with a webcam, reliable internet, a private room with a closed door, and a government-issued photo ID.
Can I take one GED subject at a time?
Yes. Each subject is its own test. Pass one and it's done; move on to the next whenever you're ready.
Is the GED hard?
It depends on your starting point. The reading-heavy subjects reward careful reading more than memorized facts, and Math rewards steady practice. Take a practice test in each subject; your results will tell you more than any general answer can.
Is a GED the same as a high school diploma?
It's a high school equivalency credential rather than a diploma, but employers and colleges widely accept it in place of one. If you have a specific goal in mind, such as a particular college program, employer, or military branch, check that program's requirements.
How much does the GED cost?
It depends on your state, and you pay per subject. Pick your state on GED.com's price and rules page to see current fees. Some employers cover the cost through the GEDWorks program, and retakes of failed subjects are discounted within set limits.
