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.

Misleading subscription model

Be aware of the subscription model.
Paid nearly £2 for the test. This payment automatically activated a £29.95 subscription. This was not clearly disclosed during checkout, and I only noticed the charge via my bank statement.
I cancelled the subscription immediately, but a refund was refused, with the company stating that the payment was "authorised" and in line with their "policy".
In my view, this business model relies on user confusion rather than clear, informed consent.

I enjoyed the brain teasers inside the app much more than the IQ test itself. I'm pretty bad at remembering stuff so I found the memory games good practice. Big up to the customer support (Seb) which has been very responsive when I requested to change my payment method. Fantastic experience overall!
