Getting started

What the test is, who it is for, and what makes it different from other free IQ sites.

What is an IQ test?+

An IQ test estimates your reasoning ability against a standard scale where 100 is the average. The score itself is not the interesting part - what each domain (verbal, spatial, logical, working memory) tells you about how you think is.

Our test asks 60 questions across those four domains, takes about 30 minutes, and uses adaptive scoring so harder questions you get right count for more.

How is your test different from other free IQ sites?+

Three things. First, the score is calibrated to the same scale a clinical psychologist uses, not an internal ”fun” score. Second, you get four domain subscores, not just one number. Third, no signup, no email gate, no paywall after the test ends.

  • Real scoring math, calibrated to clinical norms
  • Four cognitive subscores, not just a headline number
  • No signup, no email, no paywall - ever

The methodology page explains the scoring math in plain English if you want the full story.

Who can take the test?+

Anyone 13 or older. The questions and norms are calibrated for adults but work fine for teenagers and seniors too.

  • Teens (13-17): Same questions; norms reflect your age group, so your percentile is fair.
  • Adults (18-64): The default. Norms are tightest here since the largest research sample is in this range.
  • Seniors (65+): Same test. Processing-speed scores trend slightly lower with age, which the percentile accounts for.
What languages is the test available in?+

Nine languages. The questions and answer choices are translated; the scoring is identical across all of them.

  • English
  • Spanish, German, Russian
  • Chinese, Arabic, Hindi
  • Indonesian, Turkish

If you switch languages mid-test the result page will not save your progress, so pick one before you start.

How the test works

Length, format, what to expect, how to prepare.

What test variants are there?+

Three lengths, all using the same scoring math:

  • Full IQ test: 60 questions, about 30 minutes. Most accurate score with the cleanest domain breakdown.
  • Quick IQ test: 20 questions, about 15 minutes. Useful if you are short on time; slightly noisier subscores.
  • Practice questions: 10 sample items so you know what the format looks like before committing 30 minutes.
  • Specialized tests: Standalone reasoning, memory, and other sub-tests if the full IQ test is broader than what you want.
  • Brain training games: 40 short games to practice the cognitive abilities the test measures. Free, no signup.
  • Other category tests: Personality, career fit, programming aptitude, and other tests beyond IQ.
How should I prepare?+

You cannot really study for an IQ test, but you can avoid the things that lower your score:

  • Quiet space: Phone away, no notifications, nobody asking you questions for 30 minutes.
  • Rest first: Take it when you are alert, not at 2am after a long day. Tiredness drops processing-speed scores noticeably.
  • One sitting: Do not refresh or switch tabs mid-test - your answers save in the browser but timers reset.

You can take the test multiple times. Wait at least a few days between attempts so practice effects do not inflate your score.

What do I need to take the test?+

Almost nothing. The test runs entirely in your browser.

  • Modern browser: Chrome, Firefox, Safari, or Edge - anything updated in the last two years works.
  • Internet: Just enough to load the questions. Once loaded the test runs locally; brief drops are fine.
  • A screen: Spatial questions are easier on a bigger screen. Phones work but small screens make rotation tasks harder.
  • Time: About 30 minutes for the full test. Less for the quick version.

Desktop or laptop is better than phone, but the test works on every device.

Your results

How the score is calculated, what the percentile means, how to read your subscores.

What do my results include?+

Four things, all on the result page:

  • Overall IQ score: A single number on the standard 100-mean scale, computed from your responses across all four domains.
  • Percentile rank: Where your score sits relative to research norms - the same percentile a clinical psychologist would give you.
  • Per-domain subscores: Verbal, spatial, logical, working memory - each scored separately so you can see your shape, not just the headline.
  • Saveable link: Your result page lives at a unique URL. Bookmark it, share it, or close the tab - your choice.

No paywall, no email gate. Everything appears the moment you finish.

What does my IQ score actually mean?+

IQ uses a 100-mean scale where most people fall between 85 and 115. The categories most clinical instruments use:

  • Below 70: Significantly below average - clinical evaluation can help diagnose underlying causes.
  • 70-84: Below average. Most domains may need extra time or different approaches.
  • 85-115: Average - about two-thirds of the population fall in this range.
  • 116-130: Above average. Top 16 percent of the population.
  • 131-145: Gifted range. Top 2 percent.
  • 146-160: Highly gifted. Top 0.1 percent.
  • Above 160: Extremely rare - beyond the reliable measurement range of any 30-minute test, including this one.

IQ measures one slice of intelligence - academic and reasoning ability. It does not capture creativity, social intelligence, drive, or wisdom.

What cognitive domains do you measure?+

Four - the same four most modern IQ instruments measure:

  • Verbal comprehension: Vocabulary, analogies, and how well you reason through language. Tightly correlated with reading and academic performance.
  • Spatial reasoning: Mental rotation, visual patterns, fitting shapes together - useful for engineering, design, and STEM problems.
  • Logical reasoning: Pattern recognition, inference, and abstract problem-solving. The closest single measure to ”fluid intelligence.”
  • Working memory: Holding and manipulating information in your head. The cleanest single predictor of fluid intelligence in research.

Saving & support

How to save your result, contact us, or come back to it later.

How do I save my result?+

There is no account system - by design. The result page itself is your record.

  • Bookmark the link: The result page lives at a unique URL. Bookmark it and you can return any time.
  • Save as PDF: Use your browser print-to-PDF on the result page for an offline copy.
  • Share the link: The URL is shareable. Send it to a friend who took it; compare your domain breakdowns.
  • Email yourself: Optional - if you want a copy in your inbox, the result page has a send-to-email button.

No password to lose, no account to recover. The unique URL is your access.

I have a question that is not in the FAQ. How do I reach you?+

Direct email. We do not have ticketing software or a chatbot.

  • Email: dev.emirbaycan@gmail.com - read by a real person, usually replied within a day or two.
  • Privacy questions: Same email, mention ”privacy” in the subject and we will route it appropriately.
  • Bug reports: Include the page URL and what your browser is. The more specific, the faster we can fix it.

Privacy & data

What we collect, what we do not, and how anonymous your result really is.

How do you handle my data?+

Minimally. The test runs in your browser; your answers and result are stored locally unless you explicitly choose otherwise.

  • Anonymous by default: No signup. No email. No name. The result is tied to a random ID stored in your browser, not to you as a person.
  • Local-first storage: Your answers and history live in your browser. Clearing cookies clears your history.
  • No third-party sharing: We do not sell or share data with anyone. The aggregate percentile data is anonymized.
  • GDPR compliant: European users have full rights under GDPR. Cookie consent is genuine - opt out and we honor it.
  • HTTPS everywhere: All traffic is encrypted in transit. Server access is restricted and audited.

If you ever want your data removed, email us. We delete it within a few days.

What control do I have over my data?+

Full control. Your data lives in your browser by default; you decide what happens to it.

  • View it: Your result page link shows everything we know about your test - score, percentile, subscores.
  • Delete it: Clear your browser data and the local copy is gone. Email us to remove anything stored server-side.
  • Export it: Save the result page as PDF or screenshot. The unique URL also works as a permanent link to your result.
  • Skip cookies: Decline analytics in the cookie banner. The test still works exactly the same.

Technical issues

Browser support, mobile, what to try if something goes wrong.

Something broke during the test. What now?+

In order, try these:

  • Refresh the page: Your answers save locally as you go, so a refresh usually picks up where you left off.
  • Clear cache: If a question is showing wrong content, clearing site cache and reloading fixes 90 percent of cases.
  • Switch browser: If the page just will not load, try a different browser. Older mobile browsers can struggle with the spatial questions.
  • Email us: If nothing works, email dev.emirbaycan@gmail.com with what happened. We read every message.

What devices and browsers does the test work on?+

Pretty much anything updated in the last two years. Specifically:

  • Browsers: Chrome, Firefox, Safari, Edge - current and last major version.
  • Mobile: iOS Safari and Android Chrome both work. Spatial questions are easier on a larger screen.
  • Desktop: Windows, macOS, and Linux all work. Recommended for the full test.
  • Internet: Once questions load, the test runs locally. Brief connection drops are fine.
  • Screen size: Anything 1024x768 or larger is comfortable. Phone-sized screens work but cramp the spatial questions.

If something does not work on your setup and you are sure it should, send us your browser version and we will investigate.
