What the test measures
Six types of reasoning, mixed throughout the test. See examples of each.
Sequences
Find the rule linking the numbers and letters: addition, multiplication, squares, alternating patterns.
Matrices
Figures arranged in a 3×3 grid. Which one completes the pattern? Measures abstract reasoning.
Numerical reasoning
Percentages, proportions and everyday problems, no memorized formulas.
Memory
Numbers, colors and squares show for a few seconds and disappear. How much do you keep?
Spatial reasoning
Which piece is the same one, just rotated? Train your ability to picture shapes in space.
Logic and language
Analogies, deductions and "which one doesn't belong". Reasoning with words.

How long does the IQ test take?
The free test has 40 questions and takes up to 30 minutes. Each question has its own time limit. The full test has 70 questions, with 1min30 for each and up to 70 minutes in total.
Is the result an official IQ?
No. It is an estimate from an unsupervised online test, for self-knowledge and entertainment. An official psychological assessment can only be carried out by a licensed psychologist using approved tests.
Are the questions always the same?
No. Most questions are generated on the spot from mathematical rules, so every test is different. That's why we can show the answer key without spoiling the test for anyone.

Yes. QI Agora was built mobile first. We just recommend a quiet place, a stable connection and staying on the screen during the test.
