The GED Is Four Separate Tests: What to Take First and What 145 Means (2026)

You don't have to sit the whole GED at once. It's four separate subject tests, each booked separately, each paid for separately, and each passed or failed on its own. Sitting all four back to back would take about seven and a half hours, and almost nobody does it that way.

That one fact changes how you should approach this, and most guides bury it. You can pass one subject this month, bank it, and come back for the next when you're ready and the fee is there.

Here's how each subject works, what the passing score really means, and which one to take first.

The Four Subjects, and What Each One Costs You in Time

Passing is 145 on each subject, and you need 145 or higher on all four. There's no averaging and no compensation. A 170 in Science does nothing for a 140 in Math, which is the single most important scoring rule to understand before you book anything.

Cost is roughly $30 to $40 per subject, so about $120 to $160 for all four if you pass each on the first attempt. Fees are set by each state, so check yours rather than trusting a number in an article.

Take Your Strongest Subject First

This is the practical consequence of the four-separate-tests structure, and it runs against the instinct to get the hardest one out of the way.

A banked pass does three things. It proves to you that the test is passable, which matters more than people admit when you've been out of education for a while. It reduces the number of subjects you're carrying. And because you pay per subject, a first-attempt pass keeps that fee from repeating.

• The GED Study Plan Generator takes your target dates and the hours you can realistically give it, and sequences the four subjects rather than treating them as one block. Tell it the truth about your hours.
• Not sure where you stand? Generate a mixed set with the GED Practice Test Generator and let the results pick your order instead of guessing.
• Studying around shifts or family, alongside other commitments? The general Study Plan Generator handles a calendar that has more than one thing in it.

Classes Might Not Be Required Where You Live

Plenty of people arrive at an adult education office, get placement-tested, and are told how many hours of class they need before they can sit anything. That's how one creator with a widely watched video on the subject describes their own start: he was told he needed "at least 50 hours of classes" before he could even be retested, and he understood that he had to graduate those classes to get the credential at all.

He later booked the real test directly and sat it in the same building. "They didn't ask me for the amount of hours I'd put into the class. They didn't ask for my TABE scores." The class route had cost him five months.

That was one state, and this is exactly the kind of rule that varies, so treat it as a question to ask rather than an answer you already have. Check your own state's rules on ged.com's price and state rules page before you enroll in anything. Some states attach conditions, others don't. You pay the per-subject test fee either way, so ten minutes of checking is worth it.

One cheap step before you book the real thing. The official site sells a practice test per subject that predicts whether you'd pass. Paying a few dollars to learn you're ready beats paying the full fee to learn you weren't.

• Get your free reps in first, though. The GED Practice Test Generator gives you unlimited mixed sets, which turns the paid official practice test into a final check rather than your first data point.

Math Is Where People Get Stuck, and the Numbers Show It

The biggest GED videos on YouTube are hour-long math sessions. One practice video runs over an hour and has been watched more than six hundred thousand times. Another exists specifically to teach working without a calculator.

That last one isn't an accident. Mathematical Reasoning runs in two parts, and part 1 gives you no calculator. Part 2 provides an onscreen one. So arithmetic you can do on paper isn't optional here, it's a requirement.

The reason those long videos work is volume. People sit through fifty minutes of someone working problems because seeing many worked examples is what builds the pattern. Generated practice does the same thing and doesn't run out.

• The GED Math Practice Generator is the most-used prompt in this set, which matches everything above. Ask for one topic at a time and work it on paper.
• Order-of-operations slips cost more marks than hard concepts do, especially without a calculator. Run the Order of Operations Solver on the ones you get wrong and look for your repeating mistake.
• Solving for an unknown is the backbone of the section. Build fluency with the Linear Equation Practice Generator, and use the Quadratic Equation Solver when the equations get a squared term.
• Area, perimeter and circle questions are steady marks once the formulas are automatic, which is what the Circle Area Solver drills.

The Essay Has a Name, and It Isn't "The Essay"

Reasoning Through Language Arts is the longest subject at 150 minutes: three sections plus one written piece. GED calls that piece the extended response, and it asks you to read source material and argue which position is better supported by the evidence, rather than to write your opinion. Our guide to textual evidence covers how to pull and quote the lines that make that case.

• The GED Essay (Extended Response) Practice Generator produces prompts in that format, with source passages to argue from.
• The multiple-choice part of RLA tests grammar and usage you can drill directly. The GED RLA Practice Generator covers it.
• Two complete sentences joined by a comma is the error that shows up most in adult writing samples, and the Run-on Sentence Fixer trains you to see it.
• When a long phrase sits between the subject and the verb, people match the verb to the nearest noun. That's the Subject-Verb Agreement Checker.
• Before you submit any written piece, the Grammar Checker catches the mechanical marks you would otherwise hand away.

Science and Social Studies Test Reading, Not Recall

The most common wrong assumption about these two is that you need to revise biology and American history. Both sections lean heavily on reading charts, tables and short passages and drawing a conclusion from them. That's a skill you can practice directly, and it's a faster route to 145 than trying to relearn a syllabus.

• The GED Science Practice Generator builds the data-interpretation items the section uses across life, physical and earth science.
• The GED Social Studies Practice Generator does the same for civics, history, economics and geography.
• Unfamiliar words inside a passage are recoverable without a dictionary, and the Context Clues Helper drills that on its own, and our vocabulary guide lays out the four clue types to look for.
• Questions about an author's stance trip people up more than factual ones. The Tone Analyzer pushes you to name the specific register a passage uses.

Your State Might Offer the HiSET Instead

The GED isn't the only high school equivalency exam, and which one you can sit depends on where you live. The HiSET is the main alternative, and its scoring works differently in a way that can matter to you.

The HiSET has five subtests rather than four: Language Arts Reading, Language Arts Writing, Mathematics, Science and Social Studies. Reading is 65 minutes, Writing is 120 minutes with an essay, Mathematics is 90 minutes. Each subtest is scored 1 to 20.

To pass you need 8 out of 20 on every subtest, 45 out of 100 combined, and at least 2 out of 6 on the essay. Do the arithmetic on that and something useful appears: five subtests at the 8-point minimum comes to 40, but the combined bar is 45. So a strong subtest can carry you five points past the minimums.

Best for: anyone with one clearly strong subject who wants it to count for something, and anyone in a state where HiSET seats or fees are easier to get.

Skip if: your state doesn't offer it, or you would rather face four subjects than five.

• The HiSET Practice Test Generator produces items in the HiSET's own format, which isn't interchangeable with GED practice.
• Check availability on HiSET's state requirements page and GED fees on ged.com's price and state rules page before you commit money to either.

Studying After Years Away From School

Retrieval beats rereading, and that gap widens the longer it's been since you last studied. Reading a page again feels productive, and it teaches you much less than being asked a question you have to answer from memory. Our how to study for exams guide explains why, and how to space the sessions.

• Turn every missed question into a card with the Flashcard Generator, then set the intervals with the Spaced Repetition Guide. That combination is what makes short sessions add up.
• If the GED is a step toward a citizenship application or a job requirement, the US Citizenship Civics Test Practice Generator covers that separate exam in the same way.

Our prompts for students and teachers collection covers the wider studying side, and if writing is the part you dread, the 21 AI writing tools rundown covers what helps with a draft you still have to own.

One document for the whole run is worth more than four sets of notes: which subjects you have passed, what you missed last time, and your next test date. The Dock Editor is free for 7 days and keeps that beside the practice you generate.

Pick the subject you're strongest at, not the one you fear, and generate one set for it tonight. Booking that single test is a smaller decision than "getting my GED", and it's the one that starts the rest. Browse every test-prep prompt for the SAT, ACT, ASVAB and certification exams.
