ETS Praxis Core — 3 tests: Reading (5712), Writing (5722), Mathematics (5732)
CoStudy's Praxis Core (Educators) bank holds 205 items. Every multiple-choice question carries a written rationale explaining why the correct answer is correct and why each distractor is tempting but wrong.
A sample of 12 multiple-choice questions from the bank, with the full rationale shown.
Author's tone is most likely 'reverent' when the text:
Answer: C — Describes the subject with deep respect
A/B) Opposite tones. C) Correct — reverence = respectful awe. D) Reverence carries feeling beyond neutral.
Comparing two passages on the same historical figure, one calls him a 'visionary', the other a 'zealot'. The contrast in word choice reveals:
Answer: D — Different evaluative stances toward the figure
A) Same figure, not different facts. D) Correct — connotation differs; one praises, one criticizes. C/B) Not necessarily implied.
Is the median of {2, 5, 7, 11} equal to 6?
Answer: A — Yes
Even count — median is average of two middle values: (5 + 7)/2 = 6. A) Correct. B) Second value, not median. C) Third value, not median. D) Last value.
Median of 3, 5, 8, 12, 15?
Answer: B — 8
Values sorted. Middle (3rd of 5) = 8. A) Second value. B) Correct. C) Mean ((43)/5 = 8.6, rounded). D) Fourth value.
Which sentence demonstrates parallel structure?
Answer: B — She enjoys reading, hiking, and swimming.
A) 'to swim' breaks parallelism with 'reading, hiking'. B) Correct — all three items use -ing form. C) Mix of infinitive, gerund, and present tense. D) Mix of present tense and gerund.
y = 4x + 2. What is the slope?
Answer: B — 4
y = mx + b; m = 4. A) Y-intercept. B) Correct. C) Sum. D) Reciprocal.
A passage opens: 'It was the best of times, it was the worst of times.' This figure of speech is:
Answer: A — Paradox
A) Correct — apparent contradiction holding deeper truth = paradox. B) It IS an allusion, but the literary device asked is the paradox structure. C/D) Don't apply.
Median of {3, 7, 9, 11, 15, 17}?
Answer: B — 10
Even count: average of 9 and 11 = 10. A) Lower middle. B) Correct. C) Upper middle. D) Off by one.
Author's purpose in a passage filled with statistics, citations, and neutral tone is most likely to:
Answer: C — Inform readers about a subject
A) Persuasion uses urgent or evaluative language. B) Narrative uses scenes. C) Correct — neutral tone + data = inform. D) Personal feelings would be emotive.
A paired-passage prompt asks: 'How do the two authors differ?' Best strategy:
Answer: C — Identify each author's claim, then locate where they diverge
A) Misses Passage 2 entirely. B) Risks half-right reading. C) Correct — locate explicit claims, then contrast. D) Fame is irrelevant.
Roll two dice. P(sum = 7)?
Answer: A — 1/6
6 favorable outcomes / 36 total = 1/6. A) Correct. B) Off. C) Misread denominator. D) Off.
Which clue indicates an INFORMATIONAL passage rather than literary?
Answer: C — Topic sentences, data, and citations
A/B/D) All point to literary or narrative. C) Correct — structured exposition with evidence signals informational text.
6 sample cards from the 55 in the bank.
Reading strategy: paired passages?
Read first passage + answer single-passage questions. Then read second + answer paired questions comparing them.
Praxis Core Math: questions and time?
56 questions, 90 minutes. Calculator-allowed sections.
Misplaced modifier example?
'Walking down the street, the trees were beautiful.' Trees can't walk — modifier dangles. Fix: 'Walking down the street, I noticed the beautiful trees.'
Mean vs Median?
Mean = average (sum ÷ count). Median = middle value when sorted.
'Of' in math word problems often means?
Multiplication. '40% of 200' = 0.40 × 200.
What does Praxis stand for?
Praxis isn't an acronym — it's Latin/Greek for 'practice' or 'doing'. ETS uses it for teacher licensure tests.

Yes. Every multiple-choice item carries a written rationale that states the controlling principle behind the correct answer and then addresses each wrong option in turn — why it tempts and precisely where it fails. Knowing why the plausible answer was wrong is worth more than knowing which letter was right.
The samples on this page are free to read in full, rationales included, with no account. The complete 205-item bank, the timed mock exams and per-chapter progress tracking are part of CoStudy on the web and in the iOS app.
Last reviewed 2026-08-22. Banks are written against the certifying body's published exam outline and re-checked when that outline changes — exams get renumbered, retired and reweighted, and a bank written to a superseded outline teaches the wrong proportions. Figures that are re-indexed annually are deliberately not asserted as rules; the questions test the governing principle instead.
This bank is written against ETS's published exam material. Check the ETS test content specifications for the current outline, fees and eligibility rules — those change, and the certifying body is the only authority on them. CoStudy is not affiliated with ETS.
