Frequently Asked Questions

An IQ (Intelligence Quotient) test is a standardized assessment designed to measure human intelligence through various cognitive tasks. It evaluates multiple aspects of intelligence including logical reasoning, pattern recognition, mathematical ability, spatial awareness, and verbal comprehension. Our test uses scientifically validated questions that have been calibrated against thousands of test-takers to ensure accuracy.

Our online IQ test is highly accurate when taken seriously and without distractions. It uses the same psychometric principles as professional IQ tests and has been validated against standardized tests like the WAIS and Stanford-Binet. Accuracy depends on several factors: taking the test in a quiet environment without interruptions, answering honestly without looking up answers, completing all questions within the time limit, and being well-rested and focused. When these conditions are met, our test typically shows 90-95% correlation with professional assessments.

Our IQ test is suitable for anyone aged 16 and above who is curious about their cognitive abilities. It's ideal for students wanting to understand their strengths, professionals considering career decisions, or anyone interested in personal development. The test is also useful for parents wanting to understand their teenager's cognitive development.

Our IQ test takes approximately 20-30 minutes to complete. The test contains 40 questions of varying difficulty levels. While there is a time limit to ensure standardized conditions, you should not rush. Take your time to think through each question carefully. The time limit is generous enough for most people to complete all questions while still maintaining the test's validity. For best results, set aside 30-40 minutes in a quiet environment where you won't be interrupted.

Yes, you can retake the test, but we recommend waiting at least 6 months between attempts for the most accurate results. This is due to practice effects: familiarity with question types can artificially inflate scores, you may remember specific questions and answers, and true cognitive changes take time to develop. If you do retake the test sooner, your score may be 5-10 points higher simply due to familiarity, not actual intelligence improvement.

During the test, you'll be presented with 40 questions testing various cognitive abilities: logical reasoning, pattern recognition, mathematical problems, spatial awareness, and verbal comprehension. The questions progressively increase in difficulty. You have a time limit per question, but it's generous. The interface is user-friendly and shows your progress. You cannot go back to previous questions, so take your time to answer carefully before proceeding.

No special preparation is required, as IQ tests are designed to measure your current cognitive abilities, not learned knowledge. However, you can optimize your performance by getting a good night's sleep (7-9 hours), eating a balanced meal, choosing a quiet time when you won't be interrupted, avoiding alcohol or substances that impair cognition, and staying well-hydrated. Avoid taking the test when tired, stressed, or ill.

You will receive your IQ score immediately after completing the test. The results will be displayed directly on screen and include your numerical IQ score, percentile ranking, and a detailed analysis of your cognitive strengths and weaknesses. If you provide your email address, you'll also receive a copy of your results in your inbox for future reference.

The average IQ score is 100, and about 68% of the population scores between 85 and 115. IQ scores follow a normal distribution: 145+ is genius or near genius, 130-144 is very superior intelligence, 120-129 is superior intelligence, 110-119 is high average intelligence, 90-109 is average intelligence (where most people fall), 80-89 is low average intelligence, and 70-79 is borderline intelligence. A score above 130 places you in the top 2% of the population.

Yes, after completing the test, you can obtain an optional printable certificate documenting your IQ score and performance. This certificate is available as part of our detailed report. It includes your score, test date, and an official stamp. While this certificate is suitable for personal purposes, we recommend using an officially proctored test for formal employment or educational needs.

Yes, IQ scores can improve, though the extent varies by age and effort invested. With targeted cognitive training, you can expect a 5-15 point improvement over 6-12 months. Factors influencing improvement include age (younger people show more plasticity), targeted cognitive exercises, continued education, healthy lifestyle (sleep, exercise, nutrition), and familiarity with test formats. While your genetic potential sets an upper limit, most people operate well below their maximum capacity.
