This may give a general idea of your intellectual ability by showing how you cognitively compare to others. However, keep in mind no online test has diagnostic value nor can accurately give a definite result. Only in-person tests administered by a professional can accurately assess your IQ.

What is an official IQ Test exactly?
An official IQ test could be defined as an IQ test that is able to produce legit and reliable results. That’s what people commonly refer to by “official”. An accurate and real IQ test must have an acceptable degree of psychometric validity and reliability. Tests such as the Raven’s, the WAIS (Weschler Adult Intelligence Scale), or the Stanford Binet scale, are good examples of official IQ tests.
A test is said to have “psychometric validity” if what is being measured correlates with what the test actually intends to measure. If a test measures intelligence, it should correlate with how smart test-takers are, and not with, for instance, how high their emotional intelligence or their social skills are.
In the case of online IQ tests, their items must measure people’s fluid reasoning (also referred to as reasoning ability). This can be achieved by using items of different natures, such as mathematical ones, linguistic ones, or even spatial ones, but the thing is, the number of all these different types of items should be balanced.
Last, an IQ test is said to have psychometric reliability if it produces the same results (or very similar ones) after each administration.
This concept is very easy to understand. If we measured the temperature of an object several times and we obtained a different result in each measurement, (let’s assume the real temperature was the same all the time) it would mean that our thermometer is not reliable; it is probably broken.

Where to take a Real and Official IQ test?
You can take an official IQ test in any certified psychology clinic, in any HR firm or HR department willing to test you, in any faculty of psychology (which was also willing to test you) or even at school (assuming the psychology office has the necessary knowledge and resources).
However, what most people who want to take a real IQ test do is just go to a psychologist/psychology clinic that is trained in administering these tests. The entire testing process can cost between $300 and $1000.
One last option is to take an online IQ test. Online IQ tests can also have certain degree of reliability and validity if they have been developed properly enough. Online IQ tests can give a broad estimate/approximation of someone’s IQ and are really good to practice. However, they should not be used with diagnostic purposes or for drawing definitive conclusions. Online IQ tests are offered for informational or recreational purposes and not for being used as a valid assessment tool. No online IQ test can be as accurate as an in-person test administered by a professional.
