I got frustrated with online IQ tests that were either full of ads, hidden paywalls, or had no scientific basis whatsoever. So I built one from scratch using actual psychometric standards: - Raven's Progressive Matrices (the gold standard since 1936) - CHC Theory framework - Proper normal distribution scoring with error function percentiles The hardest part was calibrating difficulty across 9 languages while maintaining statistical validity. Each language version had to feel natural, not just translated. Would love feedback from anyone who takes it — especially curious whether the domain breakdown (sequence, matrix, spatial, logic) feels balanced or if one area feels too easy/hard.
