Scoring & sources
The answer key is an OpenIQ reconstruction. Three unclear items are unscored, with their section totals adjusted proportionally. Artificial Language uses its 1925 Princeton precursor and the original word-level partial-credit format.
Raw scores use the 1926 report's standardization. The IQ estimate interpolates the historical SAT/Otis comparison table; it is not a contemporary population norm or CognitiveMetrics' renorm. Values outside the published range do not receive a numerical IQ estimate.
