Science
GED Science Practice Test 3
Forty new multiple-choice questions, none repeated from Practice Tests 1 or 2. Most are built on a short passage, data table, or experiment, and the set includes items on hypotheses, variables, and reading results.
Question 1 of 40
0 answered
A nurse explains: “Red blood cells carry oxygen using a protein called hemoglobin. Patients with low hemoglobin often feel tired and short of breath, even at rest.” Which statement best explains these symptoms?
What is new in this practice test
The mix follows the official balance: 14 life science, 14 physical science, and 6 earth and space science questions. Six more questions focus on scientific practices, such as naming the independent variable, judging a sample size, or computing an average from trial data.
Several items ask for a short calculation, like a speed, a rate of growth, or a percent change. Write out the numbers from the table before you compute, and check the units in the answer choices.
Using your third score
Scores map to the 100 to 200 GED scale, where 145 passes, 165 is College Ready, and 175 or higher can earn college credit. With three results, you can see a real trend instead of a single snapshot.
If your misses are mostly on experiment questions, study the scientific practices page next. If they cluster in one content area, return to that topic’s study guide and drill before your next attempt.
Frequently asked questions
- Does Practice Test 3 repeat any questions from the first two tests?

- Why does this test include scientific practices questions?
- The real GED Science test checks how you read experiments and data across every content area, so practicing those skills directly helps on many question types.
