Praxis Core Combined Practice Test
Praxis Core Combined practice addresses foundational reading, writing, and mathematics skills used in academic study and classroom-related work. The available question bank samples reading simple data displays, drawing cautious conclusions from experiments, solving linear equations, comparing ratios, simplifying fractions, and calculating probability and speed.
Exam overview
About the Praxis Core Combined Exam
The mathematics examples call for interpreting quantities and relationships: compare values in a table, express a part-to-whole relationship in simplest form, apply proportional reasoning, calculate constant rate, and solve one-variable equations. Probability questions require identifying favorable outcomes relative to all possible outcomes. Data questions may ask for a median, so distinguish a measure of center from a greatest value or total. Writing-related examples emphasize careful interpretation of evidence: when comparing a teaching activity or an experiment, identify a useful comparison and avoid claiming more than the results support. These skills connect quantitative accuracy with clear reasoning—selecting an operation, showing how evidence supports an answer, and recognizing what a small set of observations can and cannot establish.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A student records the number of books borrowed by four classes: Cedar, 12; Maple, 18; Oak, 9; and Pine, 15. Which class borrowed the greatest number of books?
Show answer
Correct answer: BComparing the four counts, 18 is the largest value, and it belongs to Maple class.
A student is writing about an experiment in which plants receiving fertilizer grew taller than plants receiving none. Which statement is the most cautious conclusion?
Show answer
Correct answer: BA conclusion should match the limited evidence. The results support a possible effect in the tested conditions, but they do not establish a universal rule or rule out other factors.
A bag contains 5 red tiles and 3 blue tiles. If one tile is selected at random, what is the probability that it is blue?
Show answer
Correct answer: BThere are 5 + 3 = 8 tiles in total, and 3 are blue. The probability of selecting a blue tile is 3/8.
A bus travels 180 miles using 6 gallons of fuel. At the same rate, how many miles can it travel using 9 gallons?
Show answer
Correct answer: BThe bus travels 180 ÷ 6 = 30 miles per gallon. With 9 gallons, it can travel 30 × 9 = 270 miles.
A class has 18 students, and 6 of them walk to school. What fraction of the class walks to school, expressed in simplest form?
Show answer
Correct answer: BThe fraction is 6/18. Dividing the numerator and denominator by 6 gives 1/3.
A moving cart travels 150 meters in 10 seconds at a constant speed. What is its speed?
Show answer
Correct answer: ASpeed equals distance divided by time: 150 ÷ 10 = 15 meters per second.
Solve for x: 3(x − 2) = 18.
Show answer
Correct answer: CDivide both sides by 3 to get x − 2 = 6. Add 2 to both sides, so x = 8.
How to use this practice test
Access the free practice bank for a session of up to 20 randomly selected questions from the 50 published questions. After submitting the session, review the results to identify which sampled skills need more work, such as proportional reasoning, equation solving, data interpretation, or evidence-based conclusions.
Preparation tips
- For ratio and rate problems, write the known quantities with units, then set up a proportion or unit rate before calculating.
- Practice simplifying fractions by finding the greatest common factor, and verify that numerator and denominator cannot both be reduced further.
- When solving linear equations, use inverse operations in sequence and substitute the result into the original equation to check it.
- For tables and small data sets, distinguish comparison questions from requests for a total or median; order values before finding the median.
- In experiment and instructional-comparison scenarios, identify the comparison condition and state conclusions only as strongly as the evidence allows.
