GED test subjects, scores and preparation: the complete 2026 guide
IELTS specialists — MUIC & Chulalongkorn University alumni, IELTS Speaking Band 9, trained via IDP IELTS teacher courses.
The GED is a computer-based high-school equivalency test with four separately scheduled subjects: Reasoning Through Language Arts, Mathematical Reasoning, Science and Social Studies. Each subject is scored 100–200, and you need at least 145 in all four to earn the credential. Start with a diagnostic in each subject, learn evidence-based reading and calculator skills, then use timed mixed practice and an error log.
The four GED subjects
- Reasoning Through Language Arts (RLA): reading for meaning, arguments, grammar and an extended written response.
- Mathematical Reasoning: basic math, geometry, algebra, graphs and functions.
- Science: scientific reading, experiments, data and graphics.
- Social Studies: civics, history, economics, geography, arguments and quantitative evidence.
Current test times and format
GED.com currently lists 150 minutes for RLA, 115 minutes for Math, 90 minutes for Science and 70 minutes for Social Studies. The tests are computer-delivered and include multiple choice plus interactive formats such as drag-and-drop, fill-in-the-blank and drop-down responses.
You do not have to take all four subjects at once. Scheduling, pricing, eligibility and retake rules depend on your testing jurisdiction, so confirm them in your official GED account.
GED score levels
Each subject uses a 100–200 scale. You must score 145 or higher on every subject to pass the full GED. Official score levels are 145–164 Passing, 165–174 College Ready and 175–200 College Ready + Credit.
College credit or placement benefits are not automatic. The receiving college decides whether it recognises them.
What actually improves your score
GED is not mainly a memory test. Across RLA, Science and Social Studies, the repeated skill is reading a source, graph or argument and choosing evidence that supports a conclusion. Math adds equation fluency and efficient calculator use.
Practise explaining why the correct answer is supported and why each distractor fails. That review habit transfers across all four subjects.
A four-subject preparation plan
- Take a short diagnostic in every subject before choosing what to study first.
- Prioritise any subject below 145, then the subject closest to passing for a quick win.
- Build a formula, grammar and evidence notebook from real errors.
- Alternate skill drills with timed mixed sets.
- Practise RLA extended responses with claim, evidence and explanation.
- Book a subject only when several timed sets clear your safety margin.
Common GED mistakes
- Studying facts without practising source analysis.
- Reading every passage slowly instead of locating the claim and evidence.
- Using the calculator without understanding the equation.
- Writing an RLA response that summarises but does not argue from evidence.
- Booking all four subjects before checking readiness separately.
Frequently asked questions
How many subjects are on the GED test?
Four: Reasoning Through Language Arts, Mathematical Reasoning, Science and Social Studies.
What score do you need to pass the GED?
You need at least 145 on each of the four subjects. Passing three subjects is not enough to earn the credential.
Do you have to take all four GED subjects at once?
No. GED.com says the four exams can be spaced out, subject to the scheduling and eligibility rules in your jurisdiction.
What does GED College Ready mean?
A score of 165–174 is College Ready; 175–200 is College Ready + Credit. Any placement or credit benefit depends on the receiving college.
