About Mensa
Mensa International is the world's oldest and largest high-IQ society, founded in Oxford, England in 1946. Membership requires a score at or above the 98th percentile on a standardised IQ test — meaning an IQ of approximately 130 or above on most standard scales. Mensa's own admission tests cover non-verbal reasoning, pattern recognition, spatial thinking, sequences and logical deduction — deliberately designed to be culturally neutral and independent of educational background. This practice test mirrors that structure and difficulty level.

Number sequences
Identify the rule governing a numerical series and predict the next term. Progressive difficulty.
Letter and code sequences
Detect rules in alphabetic, coded and symbolic sequences — position, alternation and transformation rules.
Logical and spatial reasoning
Verbal descriptions of spatial and logical problems — the core of non-verbal intelligence testing.
Analogical reasoning
Complete analogies involving abstract relationships — shape, size, category, function and transformation.
Matrix and pattern completion
The hardest section — identify the missing element from a matrix governed by two or more simultaneous rules.
Asia Carrera
One of the most publicly known Mensa members — a former adult film actress who joined Mensa in her twenties and has been one of its most prominent public advocates, demonstrating that high IQ appears across every field and background.
Geena Davis
Academy Award-winning actress and Mensa member with a reported IQ in the top 2% — one of several high-profile creative figures who demonstrate that extraordinary analytical intelligence and artistic excellence frequently coexist.
Sharon Osbourne
Music industry powerhouse and television personality who is a documented Mensa member — a reminder that practical, social and analytical intelligence can all peak simultaneously in the same person.
