Take Mensa Practice Test1What is Mensa?
Mensa (Latin for "table") was founded in 1946 by Roland Berrill and Dr. Lance Ware in Oxford, England. The name symbolizes a round-table society where all members are equals, regardless of background, profession, or social status—united only by their high intelligence.
Today, Mensa has three stated purposes: to identify and foster human intelligence for the benefit of humanity, to encourage research into intelligence, and to provide a stimulating intellectual and social environment for its members.

2How to Qualify for Mensa
To join Mensa, you must score at or above the 98th percentile on a standardized intelligence test. This means you perform better than 98% of the general population. There are two main ways to qualify:
Option 1: Prior Evidence
Submit qualifying scores from approved standardized tests you've already taken. Mensa accepts over 200 different tests.
Commonly Accepted Tests:
- • Stanford-Binet (IQ 132+)
- • WAIS-IV (IQ 130+)
- • WISC-V (IQ 130+)
- • SAT (pre-1995: 1250+)
- • GRE (pre-2002: 1250+)
- • LSAT (95th percentile+)
Option 2: Take Mensa Test
Take the official Mensa Admission Test administered by Mensa proctors. This is the most common path to membership.
Test Details:
- • Cost: $40-$60 (varies by location)
- • Duration: ~2 hours
- • Format: Paper-based, proctored
- • Retake: Wait 12 months
- • Results: 4-6 weeks

- • Cattell III B: 148+ (98th percentile)

4How to Prepare for the Mensa Test

Ineffective Preparation
- Cramming: Last-minute intensive studying doesn't improve IQ scores
- Memorization: Trying to memorize specific questions or answers
- Over-practicing: Taking the same practice test repeatedly
- Stress: Excessive anxiety about the test outcome
- Shortcuts: Looking for "tricks" or "hacks" to beat the test
