그릇 · Geureut IQ

IQ test

Five areas, about 25 minutes. Questions get harder or easier depending on your answers, and you get your score with its margin of error.

What it measures

  • Matrix reasoning: find the rules in a 3×3 pattern. The classic measure of fluid intelligence.
  • Number series: work out the rule behind a sequence. Quantitative reasoning.
  • Verbal logic: analogies, the odd one out and short logic problems.
  • Spatial rotation: tell a turned shape from its mirror image.
  • Working memory: repeat digits backwards as the sequences grow.

How it is scored

Each question has a difficulty and a discrimination value. After every answer, Geureut updates the probability of each ability level and picks the question that is most informative for you. Your result is the expected ability, put on the usual IQ scale (average 100, standard deviation 15), with a 95% range.

Questions

Is this a real IQ test?

It uses the same kind of tasks and the same scoring model as professional tests, but it is not a clinical instrument. A diagnosis needs a test given by a qualified psychologist. Use Geureut as a well-built estimate.

Why did I get different questions from my friend?

The test is adaptive. After each answer it picks the next question to match your level, so two people rarely see the same set. Scores are still on the same scale.

Should I guess when I am not sure?

Yes. There is no penalty for a wrong answer beyond it being wrong, and the scoring already allows for lucky guesses. Skipping counts as wrong.

What do you store?

If you leave the box ticked, we store which questions you saw, whether each answer was right, how long it took, your page language and your score. No name, no email, no IP address. We use this only to calibrate the questions and the score scale.

Can I take it again?

You can, but scores usually go up on a second try because you have practised. Your first result is the most accurate.
