GED Science Practice

Life science, physical science, and earth-space themes appear, but items often hinge on experimental design, variable relationships, and evidence in a figure. You may need to identify a hypothesis, choose a control, read a trend on a graph, or decide which conclusion the data actually support—not which conclusion sounds scientific.

• Data literacy: axes, units, trends, and what a table does and does not show.
• Experimental reasoning: independent vs dependent variables, controls, and sources of error.
• Concept application: apply life, physical, or earth-space ideas to a short scenario.

Begin with Science Concepts & Data Analysis and treat each item as a short reading task. Spend a few seconds on the figure title and labels before the answer choices. After misses, note whether the error was content knowledge or stimulus misreading—most adults improve fastest by fixing the second category first.

Two or three short Science sessions per week keep chart-reading sharp without overload. Pair Science with Social Studies when you want more data practice, or with RLA when passages feel slow. Closer to test day, do mixed sets so biology, chemistry-style reasoning, and earth topics rotate.

• Read the graph title and legend before the question stem.
• Ask: “What changed?” and “What was measured?” on every experiment item.
• Eliminate answers that go beyond the data, even if they sound plausible.
• Keep a list of recurring terms (control, hypothesis, variable) and your own plain-language definitions.
