Open Psychometrics has a Full Scale IQ Test you can take. Unfortunately, the Full Scale IQ score it calculates from the subscales is a bit wonky (e.g., you can score above average on every subscale yet get a below-average FSIQ). Fortunately, there’s been a real™ study in which participants took both the Open Psychometrics test and a real IQ test (WASI-II), and the data are openly available, so we can use the Open Psychometrics scores to obtain hopefully better estimates of our IQs.
(The calculator doesn’t use your Full-Scale IQ for its predictions, but I’m making you enter it anyways, because it’s fun to make people follow arbitrary and petty rules.)
