WHAT THE IQ TEST MEASURES
Inspired by the WAIS-IV (Wechsler Adult Intelligence Scale), the test covers six areas:
- Perceptual reasoning
- Processing speed
- Working memory
- Verbal comprehension
- Numerical reasoning
- Logical thinking

You solve tasks such as matrix reasoning, number sequences, cube folding, image memory, patterns, analogies, estimation, ordering numbers and letters, logic questions and more.

WHAT IS AN IQ TEST?
An IQ test shows how you perform compared to other people. Intelligence itself is not clearly defined – it is simply what an IQ test measures. That's why only results of the same test can be compared: an IQ above 100 means you solved the tasks better than average, below 100 means worse. So don't take your score too seriously – see it as an exciting comparison with others!
