An IQ test is a standardized assessment of cognitive ability — your capacity to reason logically, recognize patterns, solve problems and process information. IQ is expressed on a scale where 100 is the average score in any given age group. A score of 115 places you in the top 16%. A score of 130 or higher places you in the top 2% — the threshold for many high-IQ societies like Mensa. IQ tests measure general intelligence across multiple domains: verbal reasoning, numerical ability, abstract pattern recognition and spatial visualization.
The modern IQ test was developed by psychologist Alfred Binet in 1905 as a tool to identify students who would benefit from special education support. Since then, IQ testing has become the gold standard in psychology and human resources for assessing cognitive potential. Unlike achievement tests, which measure what you have learned, IQ tests measure your fundamental capacity to learn and solve novel problems. Your IQ is relatively stable throughout adulthood and is one of the strongest predictors of academic and professional success.
Verbal reasoning
Vocabulary, comprehension, analogies and the ability to reason with words and language.
Numerical reasoning
Arithmetic, mathematical relationships and the ability to work with numbers and quantities.
Abstract reasoning
Pattern recognition, rule identification and the ability to reason with symbols and abstract information.
Spatial reasoning
Mental rotation, visualization and the ability to manipulate objects in two and three dimensions.
Manage your time
Don't get stuck on any single question. Skip difficult items and return if time permits. Speed and accuracy both count in IQ testing.
Look for patterns
Most questions hide a rule or pattern. Ask yourself: what changes across items? What stays constant? What relationship exists?
Read carefully
One misread word can lead to a wrong answer. Reread questions and answer choices before committing to a response.
Eliminate options
If you are uncertain, eliminate obviously wrong answers first. This increases your odds of guessing correctly on harder items.
No calculator needed
IQ tests emphasize reasoning over calculation. If a problem requires complex arithmetic, you are likely overcomplicating it.
Learn from errors
Wrong answers are valuable feedback. Review explanations to understand why you missed a question and identify patterns in your thinking.
Answer each question and receive immediate feedback with detailed explanations. This helps you understand not just the answer, but the reasoning behind it.
