    This is all so easy seriously it’s probably fake crap. Scams just for entertainment alone and not truly reflective of your IQ.

    • Carl Cheo

      I agree with you that these tests are mainly for entertainment purpose and not necessary accurate. But hey, these are free quizzes! At least they give you a rough IQ score as well as an idea of how IQ questions are like :).

  • Thanks for your IQ Test reviews. The review for IQTest.com needs an update as the results are no longer “instant”. I took their test yesterday, before I saw your review. To get my results, they required my name and email address, which I supplied. Then… they required me pay to get my results, which I didn’t do. I forget exactly how much they asked for… but this site no longer gives “instant” results.

    • Jaimie

      Yes it does, your result is emailed to you instantly without payment.

      • Brett Kelly

        Not any longer.
        I did the test, entered my details.
        Didn’t pay the $15 they asked for, and I didn’t get any results.

  • Mike

    I have scored tops at learnmyself.com and 172 on freeiqtest.net. So what? I don’t see myself as a genius given my level of privilege that has allowed me to even take this test. Maybe someday.

    • john doe

      i had scored 172 and i had discovered some mathematics rules some of them were discovered but some of them are new and the regarding is not finished yet.and i dont waste my time with inventions cause inventing is too easy for me and also it requires lots of equipments.

      • jake

        wow…you just said equipments… ****ing troll.

  • Anonymous

    the first one, iqtest.com, is FAKE! its answers are way too easy and they ask you for an email and a credit card at the end. they’ll immediately charge you ten dollars!

    • Carl Cheo

      The first one is IQtest.dk. IQTest.com emails you the IQ score for free, the payment is optional. You only have to pay if you wish to view your complete personal intelligence profile.

  • terry fraser

    I have been doing a few iq tests online and have found that if you practice your score gets higher, this way the tests do not seem alien when you take them and your not afraid of the test, the first iq test I took I did not know what the perimeters of the test were like and id bad, now I take iq tests and my score is high, I do not think people should take iq tests serious until they know what the lay out of these tests are about, but they still do not make me feel smart because now I know what to expect on iq test and it is the shock and awh that makes people do badly, I would not mind taking a real iq test.

  • Dear Carl,
    Let me say this first, WOW ! Second let me say Thank You to you for your GREAT work. One of my students was about to be expelled from school for telling another teacher that they could not teach. My remark during a faculty meeting was “There might be something to that statement”! The Dean asked me to explain. I said this “often when a students IQ is higher than the teachers, the student feels this way.” The Dean asked if “I” thought that it was possible that the students IQ was higher than this teachers and I replied that there was only one way to tell. Let us give the teacher an IQ test on Monday morning and the student the same test Monday afternoon. This we did. But, I took the time to drill the student 10 hours on Saturday and Sunday using the practice test that you supplied, and made a number wagers on the outcome! To the surprise of all (Especially) the student the score’s were as follows. Teacher 104 Student 111
    Thanks Again!

    Some of these are definitely not accurate – my results ranged from 55 (mentally retarded) to 170 (genius). Hmm….

  • liinc

    My IQ is 184

  • Georges Muller

    A few individual here may be untrue mentioning their IQ grade!
    For example, a score ranging 130 and up may not be too feasible
    when the standard deviation graph is plotted in most tests!

    Since a great number of IQ Tests are really not well-administered
    in terms of content in many fields, most people who have a hobby
    of solving puzzles, cubes, riddlesl, etc, can easily score more than
    Einstein in many IQ Tests! Second, Then, some tests try to confuse
    you with uncoordinated variant and sequence problems which might
    make sense/or no sense to even kindergarten children!

    What you have to see here is that many IQ Tests are not designed
    to assess your true intelligence, though some may appear to have
    some value. In other words, a College student IQ test should be
    different from a High School student. Any IQ test which inflate your
    percentile may be questionable.

    Furthermore, cognitive reasoning, universal math problem (Physics,
    Algebra, Geometry)–not variant/sequence jargon, weird math
    puzzles to evaluate IQ intelligence! To design a IQ Test on the
    basis of universal or axiomatic knowledge would be more
    logical than inflating a bogus score. A true genius, indeed,
    might design better IQ Tests than some I have seen!

    By not making an IQ Test look like a children’ puzzles–with a
    bunch of circles, triangles, squares to collect, non-usable
    variant/unsolvable math sequence–a reasonable grade
    would be universally accepted. Interestingly, many of these
    dally IQ tests can even assign a low score to the true geniuses!
    Which ones would I recommend as feasible? You can test yourself
    just for the fun of it, but you have to be aware that the standard
    deviation graph of your score may not be absolutely true!

  • Georges Muller

    A few here may not be true to their scores!

  • Georges Muller

    IQ tests which focus on variants/unsolvable jargon sequence math
    problems may default on the standard deviation graph. For example,
    if you score 130-160, then you have to question your results with
    those who design the test. Most IQ tests I have seen look like
    IQ tests for children–not for College, High School scholars, or
    for true geniuses. A typical or reasonable IQ test will have
    some normality with respect to the standard deviation graph

    Again, an IQ test with a bunch of math puzzles which are designed
    not to be solved (circles, triangles, squares, etc)–really give the
    appearance of children’ play. Why put a sequence math in an IQ test
    which even a Mathematician will not be able to solve (because the
    theory to solve the sequence is not valid?)

    Which ones do I recommend?

    Simply, take any, though you may encounter the same dally
    consequences with most of them! I could, as a graduate
    scholar, design better IQ tests than the ones that I had seen–
    An IQ test, for example, which is designed to make a Teacher
    in Physics downgrade in Mathematics (not assigning not even
    an average percentile on the standard deviation graph)–
    would that be a fair-designed IQ Test? You judge it for
    yourself. You see, therefore, what I am trying to tell you!

  • Programaths

    I provide 11 IQ Tests for free : http://www.programaths.be/iq-hub.html
    Some are timed and calculate your speed.
    Others aren’t timed and measure your “mental stretch”.

    That means that you may perform better at some of those. Still, if you outperform, you may consult a specialist since they are quite difficult ! In Belgium people, I do provide offline testing for free in Brussels and for transport cost outside (and something to eat and drink if very far).

  • Jaygo Tee

    It’s ironic this is a site to give a list of the top17 I.Q test sites yet they accidentally list I.Q test.com twice.. So it’s actually the top 16 sites.. tisk tisk tisk. lol

    • Joshua Cox

      One of them is IQ-Test.com while the other is IQTest.com

    • Radosław Górny

      Low IQ alert ( ͡° ͜ʖ ͡°)

  • Phil Gilbert

    There are quite a few decent free online iq tests in cluding the mensa denmark and norway ones. unfortunately, most free tests are not accurate and over-estimate IQ by up to 20 points, and further do not take into account the speed factor. http://www.iq-brain.com and http://www.nicologic.fr are two of the most accurate online IQ testing sites. They are not free but yield accurate results that are comparable to what you might achieve on a group-based proctor-administered IQ test.

  • coralrefe

    I trusted this article, went to IQTest.com, took their long quiz, and at the end they wanted to charge me $14.95 for my result.

    • Brett Kelly

      Same here. IQTest.com is NOT a free site. They don’t mention the charge until after you complete the test, hoping you’ll just pay because you’ve already done it.
