Critical Thinking Test: 20 Questions in 15 Minutes

Twenty questions across the five sections real critical-thinking papers use — rate inferences, spot hidden assumptions, check deductions, judge interpretations, weigh arguments. Fifteen minutes on the clock; nothing marked until you submit.

A critical thinking test measures how you handle claims: which inferences the facts actually support, what a statement silently takes for granted, which conclusions are forced and which merely sound right, and which arguments deserve weight. This paper uses the classic five-section format — inference, assumptions, deduction, interpretation, evaluation of arguments — the same structure the Watson Glaser and similar employer assessments are built on.

Law firms, consultancies and graduate schemes use papers of exactly this shape to screen applicants, usually at a pace of well under a minute per question. This test runs 20 questions in 15 minutes — about 45 seconds each — which matches that pressure. The five-point inference scale in section one trips up most first-time takers; read each option's wording carefully before you commit.

Scoring is one point per question with no negative marking, so answer everything. Nothing is marked while the clock runs. On submission you get your total, your accuracy in each of the five sections, and an explanation for every question — including why the tempting wrong option was written the way it was.

Watson Glaser is a trademark of Pearson. This is an independent practice paper in the same five-section format; it is not affiliated with, endorsed by, or sourced from Pearson or any test publisher, and none of the questions are taken from a real assessment.

Where to go after the report

Frequently asked questions

Is this the same as a Watson Glaser test?

It uses the same five-section structure and judgment standards (the five-point inference scale, strong versus weak arguments), with original questions rather than items from any commercial paper. If you are preparing for a Watson Glaser, the per-section report tells you exactly which of the five skills to drill.

How long is it and what is the pace?

20 questions in 15 minutes — about 45 seconds per question, matching real employer-assessment pace. The clock starts when you press start and does not pause; you can move between questions and change answers freely until you submit.

What is a good score?

Employer screens on this format typically pass candidates around the 70 percent mark, so 14 out of 20 is a sound target. The per-section split matters more than the total: a strong score built on one collapsed section still means that section needs work.

Is it free, and do I get explanations?

Free, no sign-up, no answer paywall. After you submit you get every question explained — why the credited answer is right and why the tempting one is not, which is where the actual learning happens.

How is critical thinking different from logical reasoning?

Logical reasoning papers give you arguments to dissect; critical thinking papers add judgment layers around them — rating inferences on a probability scale, deciding whether an argument is strong as well as relevant. The two overlap heavily, which is why the logical reasoning test on this site is the natural next paper after this one.
