Course Syllabus
GED® Science Mastery 2026 Syllabus — Plain-Language Path to 160+
Course Overview
This is a complete, self-study GED® Science course written for adults who did not
finish high school. You do not need any earlier science class to start. We build
from the ground floor and keep going until you can read a science passage, a
graph, or a diagram and confidently choose the answer the evidence supports.
The goal is not "barely pass." The goal is 160+ — comfortably above the GED®
passing score of 145 and within reach of the 165 College-Ready mark.
Course Information
- Program: GED®
- Subject: Science
- Length: 8 weeks
- Schedule: 3 self-study sessions per week
- Total sessions: 24
- Per session: teaching + 1 SVG diagram + 10 guided examples + 10 practice MCQs
- Guided examples: 240 (fully worked, with the reasoning shown)
- Practice questions: 240 lesson MCQs + a final mixed exam
- Instructor voice: calm, encouraging, plain-language, "I'm right here with you"
What the GED® Science Test Is
- About 90 minutes, roughly 34 questions, one score from 100 to 200.
- 145 = pass. 165-174 = College Ready. 175-200 = College Ready + Credit.
- Content weight: Life Science ~40%, Physical Science ~40%, Earth & Space Science ~20%.
- Two focusing themes run through it: Human Health and Living Systems and Energy and Related Systems.
- It is an evidence test: most questions hand you a passage, table, graph, or diagram and ask what it actually shows. Reading carefully scores more points than memorizing.
The Method You Will Use on Every Question
READ the evidence → CHOOSE what it supports → CHECK for traps. You will
practice this on all 240 questions until it is automatic.

Required Materials
- This course and its lesson practice questions.
- A notebook (paper or digital) for an error log.
- A basic or scientific calculator (the GED® uses an on-screen TI-30XS on some items).
- The official GED® formula/calculator reference sheet.
- Optional after Week 6: an official GED® Ready Science practice test.
How to Study Each Session (the routine that makes it stick)
- Read the session once, slowly, without taking notes.
- Study the SVG diagram and say the main idea out loud in your own words.
- Work the modeled example without skipping steps.
- Do the 10 guided examples; cover the answer first, then check.
- Answer the 10 MCQs from memory — no notes.
- For every miss, write one label in your error log: content, graph/table, variable, calculation, or overclaim.
- Re-answer missed questions 24–48 hours later. Spaced retrieval is what moves a score.
Score Signal (course practice only, not an official conversion)
| Practice mastery | What it tells you |
|---|---|
| Scoring 6/10 or less per session | Re-teach the session before moving on |
| 7–8 / 10 consistently | Passing readiness is forming; keep drilling graphs and variables |
| 9–10 / 10 consistently | 160+ direction; start timed mixed practice |
A Word From Your Teacher
If school did not work out the first time, that was not a verdict on your mind.
This course assumes nothing and explains everything. Show up for the 24 sessions,
keep the error log honest, and the score will follow.
Course Outcomes
GED® Science Mastery 2026 — Learning Outcomes
By the end of this course, a student who started with no science background will be able to:
Scientific reasoning (tested on every question)
- Use the READ–CHOOSE–CHECK method to answer from evidence, not memory.
- Read graphs, tables, and diagrams accurately, keeping titles, axes, units, and scale.
- Identify independent, dependent, and controlled variables and judge a fair test.
- Use science math: averages, percent change, rates such as \(v=\frac{d}{t}\), density, and simple probability.
- Tell the difference between observation, inference, correlation, and causation, and avoid overclaiming.
Life Science (~40% of the test)
- Explain cell structures, photosynthesis, respiration, DNA, heredity, evolution, ecosystems, body systems, and health data.
Physical Science (~40% of the test)
- Explain atoms and the periodic table, states and properties of matter, chemical reactions and conservation of mass, energy and heat, forces and motion, work and machines, and waves, electricity, and magnetism.
Earth and Space Science (~20% of the test)
- Explain Earth's structure and plate tectonics, the rock and water cycles, weather and climate evidence, and the solar system, Moon phases, eclipses, and seasons.
Test behavior
- Pace at roughly \(90 \div 34 \approx 2.6\) minutes per question.
- Spot and defeat GED® answer traps: extreme wording, wrong units, reversed cause and effect, and out-of-scope claims.
- Keep an error log and use it to climb toward a 160+ score.
