01For the curious

You want to know where your reasoning falls on a scale with a mean of 100, with the margin of error in plain view, and understand which kinds of problems you do best on. The report shows the number, the range, the curve and the 6 areas, in plain language.

  • The number, with its margin

    Estimated IQ and a 95% confidence range.

  • The areas side by side

    Above, at or below your overall result.

02For people who want to practice

Daily training gives you 10 exercises a day across the 6 areas, from level 1 to 5, and the level in each area adjusts to you. The games are for days without a scheduled session.

Training makes you more comfortable with these kinds of problems. We don't promise an IQ increase.

03For people who want to compare later

The retest opens 30 days after your first test, with new questions and the same yardstick. The comparison accounts for the practice effect and only points to a change when it goes beyond the margin. The most common result is "stable," and we tell you that up front.

04What it isn't for

Hiring, school admissions, civil service exams or any decision about a person. Verdict of any kind, including giftedness, intellectual disability or learning disorders.

In those cases, see a psychologist. A consultation with a psychologist uses instruments approved by Brazil's Federal Council of Psychology, an interview and supervision, and it is the right path. Read Online test or consultation with a psychologist.

An educational estimate of reasoning. It is not a consultation with a psychologist and should not be used for employment, school or health decisions.

05Age

The test compares you with people in your age group, from 16 to 19 up to 70 and over. If you'd rather not give your age, you are compared with the 20 to 29 group, and the result says so. The norms are provisional for every age group, and the 16 to 19 norms stay provisional even after recalibration.
