If you need a formal evaluation, consult a licensed psychologist. But a single number can flatten a great deal of nuance. Two people with the same overall IQ might have very different cognitive profiles — one excelling at verbal reasoning while the other dominates spatial tasks. That’s why we break your results into four domain scores, giving you a richer picture of where your particular strengths and stretches lie.

• So it’s safe to say that not all types of intelligence appear on IQ tests.
• An abstract reasoning test measures how well you can identify patterns and logical rules using shapes, symbols, and visual sequences instead of words or numbers.
