What This IQ Test Measures
Not a single number. Your answers map to six cognitive domains, so you see where you are strong and where you can grow.
Logical Reasoning
Drawing valid conclusions from rules and premises.
Pattern Recognition
Spotting the rule behind a sequence or a set.
Spatial Reasoning
Manipulating shapes and relationships in your mind.
Verbal Comprehension
Understanding meaning, analogies, and relationships in language.
Working Memory
Holding and using several pieces of information at once.
Processing Speed
How quickly and accurately you work, measured from your response times.
How We Score Your Test
Transparent by design. No black box, no inflated numbers.
Difficulty-weighted, not percent-correct
Each question carries a weight based on how hard it is, so a tough item counts for more than an easy one.
Your timing counts too
We record accuracy and response time on every question, then factor your speed into the result.
Centered on the 70 to 155 scale
Your score is placed on the familiar scale where 100 is average, with a strengths-and-growth breakdown across the six domains.
Instant and private
Scoring runs on your device for an immediate result, and your answers are stored privately, not publicly accessible.
Built on established reasoning formats and designed to get more accurate as real response data accumulates. It is a cognitive snapshot, not a clinical diagnosis.
FAQ
Frequently Asked Questions
How many questions is the IQ test?
Your test covers 30 questions across six cognitive domains, balanced so every domain is represented.
How long does it take?
About 10 to 15 minutes. You work at your own pace and there is no countdown to start.
Is the test really free?
Yes. Taking the test and getting your score is free, with no sign-up needed to start.
How is my score calculated?
A real model weights each question by its difficulty and accounts for how you answer, then centers your result on the familiar 70 to 155 scale where 100 is average. It is not a flat percentage of correct answers.
How accurate is an online IQ test?
This is a cognitive snapshot built on established reasoning formats, not a clinical diagnosis. We do not publish an accuracy percentage we have not validated, and we never inflate the numbers.
Is this an official or Mensa test?
No. It uses similar reasoning formats but is not an official, supervised, or clinical assessment, and it is not affiliated with Mensa.
Are my answers private?
Yes. Your responses are stored privately and are not publicly accessible.
Can I improve my score?
You can get noticeably faster and sharper at these question formats with practice. Be cautious of anyone promising to raise your IQ by a specific number of points.
