American Mensa’s supervised admission test consists of two components administered back-to-back. Both are timed, multiple-choice, and designed to measure different facets of cognitive ability. You don’t need to prepare differently for each; the same underlying skills — pattern recognition, abstract reasoning, logical deduction — drive performance on both. Non-verbal IQ tests, such as Raven’s Progressive Matrices, assess abstract reasoning, problem-solving skills, and fluid intelligence without relying on language or cultural knowledge.

Numerical Reasoning:

They often involve deductive reasoning, syllogisms, and identifying the next logical step in a sequence.
Many IQ tests report scores on a bell curve (normal distribution) with a mean of 100 and a standard deviation of 15.
