Rule-based deduction
Combine ordering, category, conditional, and exclusive-choice rules without importing unstated exceptions.

This non-speeded reasoning test includes rule, quantity, evidence, and verbal-inference problems—not only conventional logic puzzles. Your free review shows the selected answer, keyed answer, and worked explanation for all 24 without claiming IQ or population rank.
A learning activity, not an ability verdict
Accuracy describes only this fixed, disclosed practice set. It is not an IQ score, aptitude test, percentile, school grade, diagnosis, hiring screen, or stable estimate of intelligence.
What the free result returns
Literal counts
One point per keyed answer, six problems per family, and 24 overall—without norms or bands.
Every explanation
Review selected and keyed answer text, item-specific feedback, worked reasoning, and content rationale.
Server-side key
Before completion, the browser receives prompts and visible options—not the key, family map, or explanations.
Practice next step
Use one explanation to name a reasoning move, rework the item, and test the move in a low-stakes context.
Four balanced practice families
The fixed English form uses four families for review—not four proven psychological factors. Every family receives the same six-item denominator, while each problem samples a different documented move.
Combine ordering, category, conditional, and exclusive-choice rules without importing unstated exceptions.
Set up percentages, ratios, averages, costs, and sequential changes before doing the arithmetic.
Keep denominators, samples, association, uncertainty, and missing information visible when drawing a conclusion.
Follow scope words and passage claims without adding causes, quantities, evaluations, or background assumptions.
Administration design
Work at a comfortable pace without outside help. Choose the answer best supported by the information in each prompt. This is practice: after finishing, review every explanation, including items you answered correctly.
There is no timer in the runner and no time field in the result. Saving a draft does not reduce a score. A comfortable pace keeps the activity focused on the stated reasoning relation.
Each problem has one defensible answer under the information it states. Real-world exceptions should not be imported into closed rule problems.
Correct options are balanced across the four displayed positions, so repeatedly choosing one position is not a hidden strategy.
The browser stores stable chosen option IDs and visible wording. The key and explanations arrive only in the validated completed result.
The result makes every reasoning path inspectable instead of hiding the useful evidence behind a vague high, average, or low classification.
Evidence boundary
The content is original and research-informed, but this form is not psychometrically validated. Its intended use is low-stakes personal learning with immediate explanation review—not selection, classification, diagnosis, or prediction.
Do not use it for hiring, promotion, admission, placement, certification, clinical or educational screening, IQ or aptitude estimates, population rankings, or claims about employability, school attainment, future achievement, character, or worth.
Language adaptation
New-language versions need native writers to adapt names, currency, syntax, reading load, and everyday contexts while preserving the exact reasoning relation. At least two independent reviewers should solve every adapted item and justify its key; cognitive interviews and accessibility review must follow. Each locale receives its own instrument version and evidence. Automatic translation is insufficient and must not create duplicate indexable pages.
Questions before you start
No. It is a fixed set of 24 disclosed practice problems. The result reports literal correct counts and worked explanations. It does not estimate IQ, intelligence, aptitude, giftedness, mental age, employability, or future achievement.
The goal is to inspect reasoning, not mix it with reading speed, motor speed, device performance, or time pressure. There is no timer, speed bonus, or penalty. Work at a comfortable pace and save the draft if you need a break.
Each problem has one keyed option under the information stated in its prompt. Every keyed answer receives one point. Each family contains six equally weighted problems; the overall count uses all 24. Nothing is normed, curved, weighted, or converted to a population ranking.
Yes. The complete free result returns your selected answer, the keyed answer, item-specific feedback, a worked explanation, and the reason each problem belongs in the practice set—even when your selection was correct.
No. It is unsuitable for hiring, admissions, promotion, placement, certification, clinical or educational screening, and any other high-stakes decision. It has no norms, security controls, proctoring, or validation evidence for those uses.
No. The complete result appears immediately. A short-lived browser cache may hold only pending choices until secure server acknowledgement; the completed review comes from the exact server-scored attempt. Saving it to an account remains a separate, explicit choice.
No. A new language needs native item redevelopment, independent key and distractor review, cognitive interviews, accessibility testing, a new version, and locale-specific evidence. Automatic translation is not publication-ready assessment adaptation.
