I didn't do any IQ tests, but my IQ before i play this test was 119. Pretty accurate and good to challenge to beat your IQ.

About Check IQ | Online IQ Test
Written by the company
Check-IQ.org allows you to check your mental fitness via an online IQ test.
How our online IQ tests work?
Our online IQ test is standardized and consists of a list of questions which assess various areas of your cognitive aptitude. The questions are designed to have different levels of difficulty. While our tests are primarily built for general information and educational purposes, our research team is constantly working on new tests to improve the overall assessment of your cognitive skills.
How does the IQ test work?
You have up to 20 minutes to complete the IQ test. You may skip questions if you cannot guess the correct answer. Once you are done with the test, our algorithms calculate your overall score and sub-scores across several areas of human intelligence, and compare them to the average test taker. Your results are then normalized in order to fit the normal distribution that characterizes an IQ score: By definition, an IQ score is normally distributed around 100, with a standard deviation of 15. That process, which takes several seconds to complete, is called the IQ Test validation and we charge a fee for it.
What does the IQ test report look like
The Check-IQ report is a 15-page downloadable PDF file which you provides an estimate of your IQ score, and a breakdown of your strengths and weaknesses across five key areas of human intelligence: Visual Perception, Spatial Recognition, Pattern Recognition, Abstract Reasoning and Analytical Thinking.

i just curious how much my iq is and its not bad, i hope this web (mensa) is more accurate then before, i think this is the most challenging iq test i've ever done, btw this web isn't 100% correct, and if u got iq thats not what you want don't give up keep study. and iq doesn't always guarantee you success.
