This section responds the most frequently asked questions. We hope they help and we are more than happy to receive other questions through our contact page.
Depending on the plan you chose, it might take different time for us to compute your results and send you the certificate and achieved score. Currently, in our standard plan it can take up to six (6) hours and in the premium fast plan up to ten (10) minutes.
First take into account the time it takes for us to process your results depending on the chosen plan (see question When will I receive my Certificate?).
Second, please check your Spam folder. It happens a lot of time that it reaches the wrong folder.
If you are neither in the first nor in the second case, you probably entered incorrectly your email (so we could not contact you either)l. In that case, please reach us through our Contact page and let us know, we should be able to find your results.
Lastly, do not forget that free users will only have their score sent once they leave a review in trustpilot.
The test has three parts with thirty (30) questions in total. It usually takes about half an hour (or 30 minutes). Some people do it in about ten (10) or fifteen (15), while other in one (1) hour. But the test is not time-limited. The reason is that we do not want to evaluate speed but capacity (prof. Cattell in his research stated that both approaches, time and no-time limit tests were of interest).
The test has three parts with thirty (30) questions in total. The first part is called series, wherein three elements follow a sequence that applies a rule or pattern. The test taker needs to find the correct item that continues the sequence. The second part is the strange element in the group. In this part, the user must find which element differs from the rest. The last part is matrices and the element that best fits in the matrice shall be chosen. Take into account that sometimes there is one pattern. However, the most complex items mix two or more patterns together.
The most complex items have two or more patterns or rules that apply. Usually, when someone sees a different rule in a couple of answers, that is correct. However, an item follows best all the possible applicable patterns or rules. The test does not look just for the correct versus wrong answers, but for the “most correct” or “best” option out of all the available. This, we affirm, allows to discriminate better the highest levels of intelligence.
Also, do not forget that you will not be able to understand/catch some patterns and this is normal. The test does not intend to be easy for you or so that you can answers everything. It is intended to discover your intelligence. If you do not have the highest intelligence possible, you will not be able to see some patterns and that is the expected result of the test.
We do not offer currently the possibility of knowing the correct answers. However we plan to offer in the future this option so that everyone can understand which items were correctly answered and which not, and why another option was the most correct one.
We apply a “100 + 16x” scale, which means we use a sixteen (16) standard deviation and a one hundred (100) average score. Therefore most people will have scores close to 100, having less people scores that are further aways from any of both sides. For example, scores of 120 or 90 will be achieved by less people, and 140 or 70 will be achieved by even less people.
To arrive to this scale, we first transform our test results into a normalized bell distribution. Once done that, we apply the abovementioned scale transformation.
To simplify understanding of the results, we also communicate this in percentile terms, which tells you how much percent of the general population achieved better scores and which percentage achieved less score than you. Example: if you are in the 75th percentile, your are more intelligent that 75% of the general population and less intelligent than 25% of the population, according to the test results which must always be taken with caution.
We will explain what your IQ score means in the email that we send you with your score and certificate. Please check our scale question to understand it better. We will give you an easy to digest score in percentile terms, which will tell you what percentage of the population you beat in IQ. The IQ score itself is a more complex transformation of that score used to compute the mental age of a person. In summary, if you are in the 100, you have a normal IQ. The greater the number in comparison to 100, the more intelligent you are. The lesser, then less intelligent.
The main reasons why there could be a big difference with other tests that you have made can be:
a) Other tests have more test items. This usually helps when you discriminate high scores. Take into account that our test is short. So sometimes a couple of questions up and down can make a huge difference.
b) If by chance, the population that has taken other tests is more intelligent, while the population that takes our test is less, you will see a difference.
IQ tests lose more sensitivity the further away the score is from the average score. If you check 130 IQ is aprox. 98th percentile. 155 is 99th. Since for obtaining that score you must compare with average score, by definition, extreme scores are less reliable. And you would need longer tests, more difficult items, and proven with a highly intelligent population, to make the test reliable enough for differentiating between highly intelligent with great reliability.
In other words, our test is a short IQ test that answers better the question “How intelligent am I in comparison with normal population?” but it is not suited for differentiating well between a super intelligent and genius.
We are actually looking forward to building in the future a version of our tests with a subset of population with high IQ in order to improve the most complicated items and gain as much reliability as possible.
Yes, absolutely. In case that the paid plan does not reach your expectations or is not satisfactory in any sense, we will reimburse completely the fee you paid.
For this, please contact us here and explain what went wrong. It can take up to seven (7) business days to receive your refund in your account once it is issued from Brain-testing. We strive to give the best service and are always eager to learn ways in which we can improve.
Please do not abuse this policy! it is only meant for real cases in which it is fair to give back the money. But it is very costly to us and we incur a bank penalty for giving back money.
We currently accept payments by credit or debit cards of VISA, MASTERCARD, AMERICAN EXPRESS, DINERS CLUB and JCB. We are working hard to enable other payment methods and we hope to be able to allow paying with PayPal, Google Pay, Apple Pay, and local payment methods in every country as soon as possible. Please understand that having an ultra-secure payment environment is more important to us than offering soon more payment methods.
Our price is set in united states dollars (USD). This price is fixed and always the same. However, if you pay with a method linked to bank account in a different currency, the final fee will vary depending on the exchange rate between your country’s currency and the dollar. We hope to offer soon payment in local currencies so that this problem is avoided.
Yes, you can pay with a bank card associated to local currency. The money will be automatically converted to the destination currency by the banking system. Please note, as explained in another FAQ question, that the price will be tagged to american dollars and your charged amount could vary.
We have different plans available to take the test. Please check our pricing page for our detailed explanation.
We store your personal, and specially your test data, only for the time necessary. At the most, we store it up to one (1) year, but we usually delete everything within one (1) month. You can always, in accordance with our privacy policy, exercise your privacy rights reaching us through our contact page. Note that you data will be secret always and will never be transferred or sold to other third parties.
You will receive your test results through email. If you do not receive them within one (1) day, please contact us as soon as possible. You cannot access these results later in time, since we delete results data approximately one (1) month after carrying out the test. This is done to protect the privacy of our users and to mitigate cybersecurity risk.
