An adult cognitive reasoning estimate
Measure carefully.
Interpret humbly.
Forty-eight original problems sample fluid, quantitative, verbal, spatial, and working-memory performance. The score is an experimental estimate designed for self-understanding—not a clinical diagnosis, school placement, or employment decision.
The important limitation: a “true IQ” score requires representative age norms, demonstrated reliability and validity, standardized administration, and often a qualified examiner. This browser test has not yet been normed on a representative population. It therefore reports a conservative estimate, a wide uncertainty band, and a 145+ ceiling instead of false precision.

Best on a laptop or tablet. Do not retake for at least six months; practice can inflate the result.

If this was useful, a small tip helps keep TestMyself free. It does not affect your score, and there is no pressure.
Method note: original items; four-option scoring with item-difficulty weighting and a conservative error band. This is not the WAIS and uses no protected WAIS items. Testing principles: Standards for Educational and Psychological Testing; context for formal adult assessment: Pearson WAIS-5 overview; web testing caution: APA on responsible web testing.
