How scoring works
Raw correct counts across visual matrix, numeric, and logic items are calibrated by difficulty band and converted onto a standardized cognitive scale (mean 100, standard deviation 15). A small response-time component rewards efficient answering. Because this is a brief, unproctored online screening, treat results as exploratory rather than diagnostic.
