Start the test

How it works

  1. Take the test. Answer 30 multiple-choice questions in 30 minutes. The questions start easy and get harder, and cover:
    • pattern and matrix puzzles: find the shape, arrow or number that completes a grid
    • number problems: sequences, percentages and short word problems
    • word meaning: vocabulary, analogies and finding the odd one out
    • spatial thinking: folding paper, nets of cubes, rotations and mirror images
    • working memory: holding information in your head and re-ordering it
  2. Watch the clock. The timer starts when you open the test and keeps running even if you refresh the page. When it reaches zero, your answers are submitted automatically, so answer every question, even if you have to guess.
  3. See your result. You'll see your score, how long you took and an estimated IQ-style score. You'll also get the correct answer and an explanation for every question.
  4. Keep your results. Results are saved in this browser. Create a free account if you want to see them on any device.

Before you start

Find a quiet spot where you won't be interrupted for half an hour. Have a pen and paper ready. You won't need a calculator. A laptop or tablet makes the grid questions easier to read, but a phone works too.

This is a self-assessment for practice and interest. It isn't a clinically validated IQ test. iQ is free and kept online by donations.
