Mensa Admission Test
Train the exact reasoning skills measured by Mensa entrance exams around the world.
What is Mensa?
Mensa is the largest and oldest high-IQ society in the world. Founded in 1946 in England by Roland Berrill and Lancelot Ware, its original aim was to create a non-political, racially neutral society for bright people to connect and share ideas.
The word Mensa means table in Latin — symbolizing a round-table gathering where race, color, creed, national origin, age, politics, educational or social background do not matter. The only criterion for membership is scoring at or above the 98th percentile on a standardized, supervised intelligence test.
Today, Mensa has more than 140,000 members spread across roughly 100 national groups. Members range from teenagers to centenarians and come from every conceivable profession.
How to get in
Find a test session
Most national Mensa organizations run supervised test sessions monthly in major cities. You can book a slot online through your local Mensa website.
Take the test
Tests are timed and proctored. Formats vary by country but usually include pattern recognition, matrix reasoning, number series, and spatial tasks.
Receive results
If you score at or above the 98th percentile, you qualify for membership. Results typically arrive within two weeks, and you can join immediately.
Admission varies by country
United States
American Mensa accepts scores from more than 200 qualifying tests, including the Wonderlic, SAT (pre-1994), and supervised IQ tests administered by licensed psychologists.
United Kingdom
British Mensa runs its own supervised Culture Fair test sessions in major cities. The test is non-verbal and culture-neutral, focusing on pattern recognition and spatial reasoning.
France
Mensa France uses the WAIS or Raven's Progressive Matrices for admission. The cutoff is generally the 98th percentile, same as globally, but the administering body must be nationally recognized.
Germany
Mensa Germany offers both supervised group tests and individual assessments by recognized psychologists. They also accept high scores from German-standardized intelligence batteries.
Games that help with Mensa prep
Number Series
Spot the pattern in a sequence of numbers and guess what comes next. Mensa tests frequently use numerical progressions with alternating rules, Fibonacci-like steps, or positional operations.
Matrix 4x4
Find the missing number in a 4x4 matrix where rows and columns follow hidden rules. Matrix reasoning is a staple of Mensa exams worldwide, testing your ability to detect multi-dimensional patterns under time pressure.
Mental Rotations
Pick the shape that is the same figure as the reference, just rotated. Spatial reasoning tasks like this appear on many Mensa variants, especially in cultures where non-verbal testing is emphasized.
