Welcome to the site with IQ testing, brain testing and much more. Here you can practice IQ questions for free or take a real IQ test. There are also many brainteasers present. In all levels of difficulty. There are both free tests and tests with a certificate for a fee. Due to the many tests that are carried out and the expertise I have with IQ testing, the IQ test produces a reliable result. So look further and rack your brain!
There are also many sites where IQ tests are administered, but most of them are not really reliable. There must also be at least 30 questions in 5 different categories. This gives a good idea of the intelligence. For an IQ measurement that is even more realistic, you can take it from a psychologist or Mensa. However, this often costs quite a lot of money and takes a long time. This site provides an estimate that it will take a maximum of 40 minutes to get a reliable result.
