Question 1

Is the Quotient IQ test free?

Accepted Answer

Yes. The test itself — every puzzle, the adaptive engine, scoring, the per-domain charts and your estimated-IQ band — runs entirely in your browser at zero cost, so it is free and unlimited forever. The only optional paid extra is the AI-written deep cognitive profile, which is free up to a daily limit (one a day signed out, five a day signed in) and then costs a few credits.

Question 2

How accurate is an online IQ test like this?

Accepted Answer

Quotient gives an honest estimate, not a clinical score. It reports a band and percentile with a confidence interval that narrows as you answer more questions — never the fake "±2 IQ points" precision that paid tests advertise. It is for self-reflection and entertainment, not a diagnostic, clinical, or Mensa-qualifying assessment.

Question 3

What does the test measure?

Accepted Answer

Six CHC cognitive domains: Fluid Reasoning, Visual-Spatial ability, Working Memory, Processing Speed, Verbal/Crystallized knowledge, and Quantitative reasoning. The Quick mode (~10 minutes) focuses on fluid reasoning; the Full mode (~30 minutes) covers all six and gives a tighter, more complete profile.

Question 4

Can I cheat or look up the answers?

Accepted Answer

No — that is the point. Every puzzle is procedurally generated on the fly, so the items are infinite, never-repeating, and not googleable. Unlike fixed-bank tests, you cannot memorize or look up the answers.

Question 5

Is it adaptive?

Accepted Answer

Yes. Each domain runs its own difficulty ladder: answer correctly and the puzzles get harder; miss and they ease off. This zeroes in on your real ability faster than a fixed test and keeps the experience challenging but fair.

Question 6

Do I need to create an account?

Accepted Answer

No account is needed to take the test or see your results. Signing in (free, no card) saves your result history and raises the AI-profile daily limit from one to five.
