YZR

Forty problems. One honest estimate.

For people 18 or older.

YZR is in a private test, by invitation only.

Invitations are not open to the public right now.

Which piece completes the grid?

?

Pick A to F. This one is practice.

Pronounced wiser. This is an estimate on a standard scale (mean 100, standard deviation 15). It was not measured on a sample of YZR users. The margin is provisional, about ±8 points, and may be wider. It is not a clinical or diagnostic test.

How the book works

  1. Answer 40 puzzles

    1. Answer 40 puzzles. Patterns, numbers, words, shapes, and puzzles where you look at something and then recall it.

    1. Responda 40 quebra-cabeças. Padrões, números, palavras, formas e quebra-cabeças em que você olha e depois lembra.

  2. See your bracket, free

    A free bracket in words, and your strongest area, right after the last problem. The margin is provisional, about ±8 points, and may be wider.

A few questions are timed, and a few show something for a few seconds and then hide it. We tell you before each one.

One provisional margin, not a verdict.

Every estimate is printed with a provisional margin, about ±8 points, on YZR's scale, next to how you did in each area.

How we score it

Example only. The margin on an estimate is provisional, about ±8 points, and may be wider. This illustration is not that margin.

What YZR is not

  • Not a clinical or diagnostic test. It is for entertainment and curiosity.
  • Not compared with a sample of YZR users. A rank is a percentile on a standard scale (mean 100, standard deviation 15).
  • Any summary issued here is issued by the platform. It is for entertainment and curiosity. It has no clinical, professional, or academic validity, and it is not an official IQ certificate.
