Science
GED Science Practice Test 6
Forty new multiple-choice questions, none repeated from earlier tests. This set leans on population growth and competition, evidence for evolution, the periodic table, power and efficiency, natural hazards, light-years and seasons, and tables with more than one variable. Many questions ask which statement the data support, so the skills below focus on ruling out choices that sound right but go beyond the passage.
Question 1 of 40
0 answered
A wildlife biologist tracks four male deer in the same herd for their whole lives. Deer 1: largest antlers, lived 12 years, 2 surviving offspring Deer 2: average antlers, lived 7 years, 9 surviving offspring Deer 3: smallest antlers, lived 10 years, 4 surviving offspring Deer 4: large antlers, lived 4 years, 1 surviving offspring In terms of natural selection, which deer had the greatest fitness?
Rule out choices before you pick one
On GED Science, the wrong choices are rarely random. Most are built from a common mistake: reversing cause and effect, using the wrong row of a table, or stating something true that does not answer the question. Before you pick an answer, cross out every choice you can prove wrong from the passage. If two choices remain, compare them word by word and look for the one detail that breaks one of them.
After this test, look at each miss and name the trap you fell for. Did you pick a true fact that did not match the question? Did you read the wrong column? Writing the trap down makes it easier to spot the same pattern next time.
Stay inside the data
Several items give a table with two variables, such as two fertilizers at three watering levels or two battery brands at two temperatures. Read across each row and down each column before you look at the choices. A choice that uses words like every, always, or only must hold for every row, so one counterexample rules it out.
Watch for choices that bring in facts the passage never mentions, such as rain, cost, or distance from the Sun. Even if such a statement could be true in real life, it is not supported by the data you were given, and the question asks what the data support.
Frequently asked questions
- Is Practice Test 6 harder than the earlier GED Science tests?
- It follows the same mix of topics and difficulty, but it puts more weight on areas earlier tests covered less, such as population change and the periodic table. A lower score usually points to one of those areas rather than to a drop in overall skill.
- What should I do if I often narrow a question to two choices and pick the wrong one?
- Go back to the passage and find the exact sentence or number that each choice depends on. The correct choice will match the passage fully, while the other one will add, reverse, or stretch a detail.
