Frequently Asked Questions

Our test uses scientifically-designed questions covering pattern recognition, logical reasoning, spatial awareness, and numerical ability. While no online test can replace a professional assessment by a licensed psychologist, our methodology provides a reliable estimate of cognitive ability based on your performance compared to our global user base.

The test consists of 25 questions with a 60-second time limit per question. Most users complete it in 15-20 minutes. The time pressure is intentional as it measures quick thinking and cognitive processing speed.

Our test includes four categories: Pattern Recognition (visual sequences), Logical Reasoning (deductive problems), Spatial Awareness (3D rotation and visualization), and Numerical Ability (number sequences and math puzzles).

IQ Tester is designed for entertainment and educational purposes. While we use cognitive science principles in our test design, only a certified psychologist can administer an official IQ test. Think of our test as a fun way to challenge your brain and compare yourself to others.

Your score is calculated server-side using a normalized distribution. We analyze your accuracy, speed, and the difficulty of questions answered correctly. Your performance is compared against our global user base to determine your percentile and estimated IQ on the standard scale (mean 100, standard deviation 15).

IQ scores follow a bell curve: 85-115 is considered average (68% of population), 115-130 is above average, 130-145 is gifted, and 145+ is highly gifted. About 2% of people score above 130, and only 0.1% score above 145.

Different tests use different methodologies and question sets. Our scoring is calibrated against a large user base. Some tests may inflate scores for engagement, while we aim for accuracy. Consistency in your scores across multiple attempts is more meaningful than the absolute number.

While your underlying cognitive ability is relatively stable, you can improve your test-taking skills and problem-solving strategies with practice. Regular mental exercises can enhance certain cognitive functions. Track your progress with our daily streaks feature!

You can take one test per day. This ensures fair competition on leaderboards and encourages users to perform their best on each attempt. The 24-hour cooldown also prevents score manipulation through repeated attempts.

Your progress is saved, and you can resume from where you left off within a short time window. However, the timer continues running, so we recommend completing the test in one sitting without distractions.

No, once you start a question, the 60-second timer continues. This is by design to measure your quick thinking ability. Make sure you have a quiet, distraction-free environment before starting.

Once you submit an answer, it cannot be changed. Take your time within the 60-second limit to ensure you're confident in your choice before submitting.

We have multiple leaderboards: Global (all users), Country (users from your country), and Weekly (resets every Monday). Your highest score counts for ranking. You can opt-in or opt-out of public leaderboards at any time.

The Top 1% Club is an exclusive badge for users who score in the top 1 percentile globally. This typically requires a score of 135+ IQ. Members get a special badge displayed on their profile and leaderboard entries.

Leaderboards are updated in real-time. Your new score appears immediately after completing a test. Weekly leaderboards reset every Monday at midnight UTC.

Yes! Go to your Profile settings and toggle off "Show on Leaderboards". Your scores will still be recorded for personal tracking, but won't appear publicly.

No! You can take the test anonymously. We create a temporary anonymous account to store your results. However, creating an account lets you track progress across devices, maintain streaks, and appear on leaderboards with your chosen display name.

Yes! We use industry-standard encryption and never share your personal information with third parties. Your test answers are processed server-side for security. Read our Privacy Policy for complete details.

Go to Profile > Settings > Delete Account. This will permanently remove all your data, including scores, streaks, and leaderboard entries. This action cannot be undone.

Yes, you can change your display name once every 30 days through your Profile settings. This helps prevent abuse while allowing legitimate name changes.

Complete at least one test per day to build your streak. Your streak count increases each consecutive day you participate. Streaks reset to zero if you miss a day. Longer streaks unlock special badges!

Badges include: First Test (complete your first test), Streak Master (7+ day streak), Perfect Score (100% on any test), Top 1% Club (elite ranking), Global Top 100 (reach top 100), and more. Collect them all!
