An IQ test built with the same item formats and the same time limits as a real intelligence test.
What makes it different
- 52 items, 5 sections, about 14 minutes. Each section is timed and most people do not reach the end — as in real intelligence tests, how far you get within the time is part of what is measured.
- Each section opens with a worked example, with the answer shown and no time limit.
- No language, no school knowledge. Every item is made of figures and numbers only, so everyone solves the same items whatever language they read.
- The result is a range. The number of correct answers is not the score; ability is estimated through per-item difficulties (item response theory) and shown with a 95% confidence interval.
- Different items every time. Items are generated fresh for every sitting; you never see the same one twice.
- Results stay on your device. Nothing is sent to a server.
- No ads while the test is running.
