Our test is based on the proposals of professor Cattell from Harvard University. Prof. Cattell developed a test that focuses exclusively on fluid intelligence, which is the capacity to reason and understand rules and patterns.
Fluid intelligence is only one of the capacities that are part of global intelligence under the Cattell-Horn-Carroll model of intelligence, which is the most proven model of intelligence.
However, since the correlation between fluid intelligence and global intelligence is very high, it is considered that testing for fluid intelligence is a fast and reliable method of predicting the global intelligence of a person without the cost of evaluating every intelligence capacity.
The test is made up of three (3) parts: Series, Differences and Matrices. Although each section is time-boxed to ten (10) minutes, most users finish them under the time limit. Usually the full test takes around twenty (20) minutes.
Do not hurry and take as much as needed in order to obtain the best possible score.
Every question has only one possible answer. Complex items combine several patterns or rules that apply. The correct item is the one that follows the most rules or patterns applicable and therefore fits best. If you are seeing more than one answer with the same amount of applicable rules or patterns is because you have not detected yet a more complex combination of rules that can be applied.
It is very normal for this to happen, since questions get more complex until they reach a point where your intelligence does not allow you to discriminate the rules correctly. That is the expected behavior of the test and what allows to discriminate the level of intelligence, by knowing which level of combinations one can correctly see.
You can do the test for free and enjoy the whole experience without having to pay anything. At the end of the test, you will find out your IQ Category for free.
In this way, you can experience how much you like the test, understand the category that you have been assigned and decide if you want to purchase any of our reports. You won’t regret doing it.
We process our payments with Stripe, so you can pay with all the methods that they offer. You can check their full list here or you can simply see all the available methods for your country on our payment page with Stripe. In general, you will be able to pay with all credit and debit cards (Visa, MasterCard, etc…), Wallets (Google Pay, Apple Pay, etc…), Bank redirects (iDEAL, Sofort, etc…), and Buy Now Pay Later methods (Afterpay, Klarna, etc…).

It is not necessary to provide any reason, simply let us know through the contact page that you are not satisfied. In order to improve, we always ask for voluntary feedback. Please do not abuse this policy.
Our scores are real, and you can verify them yourself by buying our report with all the answers explained. Take into account that our test evaluates solely fluid intelligence.
If you want to be highly precise, you would need to perform an intelligence test like the Wechsler Intelligence Scale with the help of a licensed psychologist. Such a test evaluates all the different abilities of intelligence according to the Cattell-Horn-Carroll theory (CHC-model), the most validated intelligence model. But be warned, it will be expensive and time-consuming.
Our psychometric analysis and the global feedback from our users indicate that our test is highly reliable. However, sometimes the score you obtained with us could be different from another IQ Test.
First, take into account that there is always a certain degree of error in every test. Even if you take the same test again, your scores can vary. Focus more on the IQ range which tells with greater reliability within which values your real score might be.
Second, as some tests evaluate different abilities and have a different number of items, differences are common but should be small.
Third, it is very difficult to discriminate between highly intelligent persons (since there are fewer people to compare with) and therefore it is normal that their scores suffer a lot of variability.
Since different IQ tests have a different number of items, the scores obtained in any test cannot be considered the IQ. Those test scores need to be transformed to the IQ scale upon which most scientists and IQ testers have agreed in order to be able to compare results between different tests. For this, we use the common scale of average 100 and standard deviation 16 (100 + 16x). That means that an average user would get a score of IQ 100. Scores of 120 or 90 will be achieved by fewer people, and 140 or 70 will be achieved by even fewer people.
Some tests use this same scale, while others use one with a standard deviation of 15, but the difference is not very big. Imagine that the average number of correct answers in our test is 15, while on another test double as long as ours is 30, then users that achieve those amounts of correct answers in each test would both get an IQ score of 100.
If more than ten (10) minutes have elapsed without receiving the results in your inbox, there are several possibilities. 1. Check your spam folder.2. You could have introduced your email wrong, in that case contact support.3. Due to the weight of the files, sometimes email providers reject them, so please contact support in that case too.
Yes, if there was some kind of misspelling in the certificate or reports, or you need to change how the full name is displayed, let us know through the contact page and we will send you as soon as possible the modified version.
We store your data only as long as needed. Our general procedure is to delete all test and personal data within one (1) year. Your data will always remain private and will never be transferred or sold to third parties. You can exercise your privacy rights at any moment if you want your data to be deleted immediately by letting us know through our contact page.
We do not offer currently a dashboard to download your results. Our results are sent by email once the process has been completed. If you wish to receive again your results, let us know and we will prepare again your results, certificate and report and send them through email. Take into account that we only store the results for a certain period of time -generally one year- in order to protect the privacy of our users, so this will only be possible if the test was performed within the period of storage.
