Want one skill only? The abstract, logical, numerical, spatial, verbal and pattern tests each take eight to twelve minutes and explain every answer. No online test can give a clinical IQ, as how results work explains. For children aged 5 to 11, use the picture puzzles for children with a parent or teacher.
