Praxis Fundamental Subjects: Content Knowledge Practice Test

The Praxis Fundamental Subjects: Content Knowledge practice page covers broad academic knowledge applied across common school subjects. Available questions sample proportional reasoning, geometry, reading comprehension, civics, life science, physics, ecology, population density, and basic computer use. These examples emphasize interpreting short scenarios, selecting relevant information, and applying core concepts rather than recalling isolated terms.

About the Praxis Fundamental Subjects: Content Knowledge Exam

The question set calls for several kinds of cross-subject reasoning. Mathematics items may require setting up a ratio, calculating perimeter or density, or applying a formula such as gravitational potential energy. Reading tasks focus on identifying a passage’s central idea. Science scenarios ask you to connect cell structures with photosynthesis, describe forces on moving objects, and explain decomposers’ roles in ecosystems. Civics questions involve recognizing how public participation relates to local government. A basic technology task tests whether you can distinguish commands such as saving a copy from replacing an original file. Together, these tasks exercise calculation, evidence-based interpretation, conceptual explanation, and practical decision-making—the kinds of skills useful for working with academic content across subject areas.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A recipe uses 3 cups of flour for 12 servings. At the same rate, how many cups of flour are needed for 20 servings?

  1. A4
  2. B5
  3. C6
  4. D8
Show answerCorrect answer: B

The recipe uses 3 ÷ 12 = 0.25 cup per serving. For 20 servings, 20 × 0.25 = 5 cups.

Question 2

Which sentence best states the central idea of a paragraph explaining that wetlands absorb floodwater, filter pollutants, and provide habitat for many species?

  1. AWetlands have several important environmental functions.
  2. BSome wetlands are located near rivers.
  3. CPollutants can enter waterways after storms.
  4. DMany species migrate between habitats.
Show answerCorrect answer: A

The listed details describe multiple benefits of wetlands, so the broad statement about their important environmental functions best captures the central idea.

Question 3

A city council holds a public meeting where residents can comment on a proposed local ordinance. This most directly illustrates which principle?

  1. AJudicial review
  2. BPublic participation in government
  3. CSeparation of powers
  4. DFederal preemption
Show answerCorrect answer: B

A public comment period gives residents an opportunity to express views and influence local decision-making, a form of civic participation.

Question 4

In a plant cell, which structure is primarily responsible for converting light energy into chemical energy during photosynthesis?

  1. AChloroplast
  2. BMitochondrion
  3. CNucleus
  4. DCell membrane
Show answerCorrect answer: A

Chloroplasts contain chlorophyll and carry out photosynthesis, converting light energy into chemical energy stored in sugars.

Question 5

A person pushes a box across a level floor at a steady speed. Which statement best describes the net force on the box?

  1. AIt is zero because the box’s velocity is constant.
  2. BIt points forward because the person is pushing.
  3. CIt points backward because friction is present.
  4. DIt increases as long as the box continues moving.
Show answerCorrect answer: A

Steady speed in a straight line means constant velocity, so acceleration is zero. By Newton’s second law, zero acceleration means the net force is zero; the push balances opposing forces such as friction.

Question 6

Which statement best describes the function of decomposers in an ecosystem?

  1. AThey produce sunlight for other organisms.
  2. BThey break down dead matter and return nutrients to the environment.
  3. CThey consume only living plants and prevent nutrient cycling.
  4. DThey convert oxygen directly into soil minerals.
Show answerCorrect answer: B

Decomposers such as fungi and many bacteria break down dead organisms and wastes, making nutrients available again in ecosystems.

Question 7

A town has a population of 18,000 people and covers 60 square kilometers. What is its population density?

  1. A30 people per square kilometer
  2. B300 people per square kilometer
  3. C1,080 people per square kilometer
  4. D18,060 people per square kilometer
Show answerCorrect answer: B

Population density is population divided by area: 18,000 ÷ 60 = 300 people per square kilometer.

How to use this practice test

Access the free practice session to answer up to 20 randomly selected questions from the available bank of 50. After the session, review your results and revisit any missed concepts, such as ratios, central ideas, civic participation, or ecosystem functions.

Preparation tips

  • Practice translating word problems into equations before calculating ratios, population density, perimeter, and potential energy.
  • For reading items, identify the central claim first, then distinguish supporting details from the passage’s main point.
  • Review how photosynthesis, decomposers, and net force relate to observable processes in living systems and everyday motion.
  • Connect public comment at a local meeting with civic participation and the process of considering ordinances.
  • Practice common file-management commands, especially the difference between saving changes and creating a separate copy.
