IQ speedtest by IQ nexus, made by Olav Hoel Dørum, who is the guy that designed the Mensa Norway IQ Test, along with other tests/puzzles. Im currently working on some other videos, should be out in a few days.
In this video I go through each of the puzzles and try to explain what the correct answer is and why.
Please let me know in the comments if you find interesting IQ Tests that you want me to check out!

Hi! Great video as always Puzzles & Solutions. I'm the one that made the test.
Item 23 has a poor design as it does not give enough examples (the squares are all in the same shape rather than communicating a concept). The system is that there are three collections of objects (square, a plus sign and lines) that increase by one for each vertical line. It could be B or E, but the objects are not connected to each other - so it's E. The idea behind the item is good, but the execution was bad. I was tempted to correct it. The item floats -- as it shows decent correlation with the rest of the items -- but not very optimal as it rises some questions.
It's not always about the statistical properties that matters, but the impression of fairness and clarity. Since so many people reacts to it (even if it's biased) I will see what I can do about it. This is why I like videos and discussions about my work, as it's improves the product.
Hey! Many thanks for the compliments. It's always nice to see you here.
The test was good. The time limit was perfect for the difficulty and amount of items. Wish you would make some website with a full collection of your tests (with clickable answers!!).
I have had some thoughts around such puzzles as item 23. These type of puzzles have a consistent pattern (signal) but contains all of this random noise. Using item 23 as an example:
-The signal (the pattern) would be; type of shape and amount
-The noise would be; movement of the objects and bending of the objects
I think the noise of these types of puzzles are great for sparking discussion about the puzzles. If every aspect of a puzzle is clear to most people, then there is no reason to discuss it. Because of this, I think they are good. Really hard puzzles are also great for sparking discussion. However in some puzzles such as item 23, I think it can be really hard to distinguish noise from signal. As you metion, I think row 1 should be altered to illustrate the concept behind the puzzle. Also I think at least one other image in the matrix should feature bending and not only image 8.
I can try to explain my first impression of item 23. First I see that every image in row 1 is completely constant while in row 2 the images are different. This made me think that the pattern is most likely in the columns. The first column and second column are quite similiar but yield very different third images (straight lines versus curved lines). I give up on making sense of the columns. I follow the rows and see the 1, 2, 3 pattern which leads to answer E. After answering E, I have this doubt in the back of my mind that there was some pattern in the columns, but which I couldnt see.
I think thats the real difference between item 23 and the rest of the items. With the rest of the items, I had confidence in my answers while with item 23, all I had was doubt.
But yeah, great test! Hopefully I will see more of your puzzles/tests in the near future :)
Already working on next video about how to intuitively think about the diagonal patterns that I often use to explain my puzzles. Also I will stream a cool puzzle game called "superliminal" sometime within the next days. The game has puzzles which you have to solve based on perception of objects. Feel free to follow me on twitch if you wanna catch that stream: www.twitch.tv/pas1729 :) [I might make a video about the game itself, im not sure yet]
Spatial ability is of particular interest to cognitive researchers, given it's role in aiding the understanding of many concepts and info. The brain must use space relationships to help organise precursors for logical reasoning. However, it's possible that image's are not fed though any complex algorithm, to be computed and ordered, instead, images are stored somewhere, then, during the reasoning process, we grab said image, and are then able to manipulate it, perhaps get some part of the image from image x then connect it to image y, ect ect, we capacity to manipulate the stored images allows for spatial reasoning. We can now manipulate images with accordance to what we want, we can correspond those manipulated images to other information to help understand concepts. This may be like visual analogical thinking. Our capacity for imagination is determined by the quantity of ways we can manipulate, re- frame the images
People are reasoning like einstein (yall so good) for 23, whilst a simpleston like me sees it this way:
Row 1: Row one is diamonds, rotated in every angle will still be the same shape + position (same shape)
Row 2: Crosses, played around different rotations and positions (same shape)
Row 3 is where things get diff a bit:
3 **unconnected** lines. Instead of simple rotation and changing of position, it changes characteristics (bend) though it still behaves like the previous two rows. From this we can eliminate:
Option A,C,D F,: Addition and subtraction of Lines --> The previous rows show no change in quantity, Therefore the final answer has to have 3 lines
Option B: Connected lines--> remember when I said the picture shows **unconnected** lines? This is where the rule applies, option B has 3 connected lines, which leads us to eliminate it automatically
ANSWER: E
REASONING: 3 unconnected lines, rotated and position changed.
Our brain makes sense of information by finding a hypothetical correspondence. Auditory and visual information is fed through the sensory system, higher order cognitive regions can grab the sensory information, manipulate it and re frame it, you are now able to perceive hypothetical situations. Situations that are beyond what you have experienced. Logic is understood through perception (perceived coherence) , Communication is in involved in guiding the representations to correspond to relevant information, so that one perceives the answer faster. Thus logical reasoning can be broken into two conceptual stages at the neuro-chemical level. Some of the process is consciously experienced by us, some of it is not.
In number 29, the middle portions were serving as the axis mirroring functions applicable to the first column items; row 2 for example is mirrored vertically.
I think number 23 is simply, going downwards; one shape, 2 separate shapes, then 3 separate shapes. So only E follows that pattern, B is similar with 3 lines but they are touching and not separated therefore nothing defines them as clearly separate.
Man it got scary once i've realised, that You gave full 30 questions on this test. Thought it was more like 15 or 20...
I'd say that, in 23, looking at the crosses, first column and second column are turned 90 degrees clockwise, so provided that in 3rd column they turn the crosses just 45 degrees clockwise, It would probably imply that the answer would not have the three lines bended so maybe just two of them. It's like the "on my way" totally bended three lines with only two of them somehow bended.

I contacted him with my answers. I got the same as you (including E for 23) except for 29, for which I got C. He replied back saying I got 29/30 correct and that corresponds to an IQ of 145/top 0.01%, which is the ceiling of the test. This leads me to think there is a 1 question grace zone like on other tests.
Hope this helps. Have a good day :)
Great!! Your respond makes me believe that every single answer I provided was correct, I think your one wrong answer was puzzle 29. Hopefully someone else also gets feedback but where they answer A for puzzle 29.
Also for the scoring, they probably use the same scoring at the other mensa tests, Maybe I can work out a scoring system.
@@PuzzlesAndSolutions Yeah, the wrong one has to be either 23 or 29, for sure. For 23 I had the same thought process as you ("It's got 3 lines, I'll go for E"). For 29 I had a quick look with about 10-20 seconds left on the clock so put C thinking it might be rotating 90 degrees along the diagonal, but looking at it with more time after I also thought it was probably A instead.
Glad I could help, though I'm still a bit stumped on the full logic for 23 haha.
@@britishtf2 I thought it was C in puzzle 29 because I thought that it was an addition/cancellation problem in the rows and/or columns, and then rotating the answer by 180 degrees. I get why it’s A and it makes more sense, but doesn’t that work too?
You realize that that IQ of 145 is only valid if you haven't practiced IQ tests. You said you were "reading along diagonals". That is not allowed because other people who are untrained don't do that. Sorry to break it to you. You are probably more like 130.
@@TheCG7 I only do these for fun. I was just trying to help (by corroborating with my answers) by providing what I got and my thoughts behind it all. When I first found these "IQ" tests (Norway, Finland etc.), I scored something like 135-140, if you care about that. Though, it's all a bit moot because of all the flaws of IQ in general, and in particular these online tests. Anyone doing these to try to get a truly accurate measure of IQ is likely misguided.
Question 23:
We need 3 lines that are in the same diatance from each other, and also they all have to be the same lines. The answer is E
"Item 23 has a poor design as it does not give enough examples (the squares are all in the same shape rather than communicating a concept). The system is that there are three collections of objects (square, a plus sign and lines) that increase by one for each vertical line. It could be B or E, but the objects are not connected to each other - so it's E."

@@PuzzlesAndSolutions nice. how about making a video about tri-52, the test is available right now
@@yuvalzaydner5440 Im googling for it right now, but I cant find it. Do you have a link?
25/30, the author took ~3 days to reply to me. I do not know if all of the questions are counted equally, but my final score was >130. Do not know how precise it is though.
Was ir greater than 130 or less? What is a exact score?
Great video and great channel. I have the impression Scandinavians are a high IQ people which can be gleaned by their world-class standard of living.
This is great work of the author . Diagonals are important , element 3, 5, and 7 are alike and 2, 4 and 9 are alike ( and 1, 6 and 8 ) Is it posible to prove this mathematicly?
Lmao for 23, my answer is E.
Take the second row, join the centres of each cross. For the first figure, it's a vertical line,second figure is a horizonal line. Considering the two lines as vectors, the resultant in the thirst figure must give 45 degrees when connecting the centres of the two crosses.
Likewise, for the third row, the line joining the first and second figures are vertical lines. Taking resultant,for the third figure must also be vertical,as seen in option E.
How well one performs on these visual pattern tests is largely predictive of how well someone learns science, expecially chemistry and biology, as it predicts how well one learns the patterns of phenomena in science. It is less predictive of how well someone learns physics, as physics is less pattern based and more deductive.
I think 3d rotations/being able to mentally visualize physics problems, helps a lot. At least for simple mechanic problems and using coordinate systems.
@@PuzzlesAndSolutions if the subtest demands spatial ability then yes, as it aids thinking in science, including physics. In fact, in mechanical reasoning, lots of problems can be solved purely though a spatial visualisation approach, but even when problems cannot be solved purely through visualisation, spatial ability still helps aid thinking by transforming words to images or by holding an image whilst manipulating as you consider different viewpoints about something then see the effects of that through visualisation.
4/30 at 18,30 minutes. Where can i check my score?
mine is only 27/30, for #23 I have a diff understanding, they are all symmetrical pics, and the symmetrical lines are different, for first column, the symmetrical line is vertical line. second column is horizontal line, third col is diagonal line
Great video man 👍👍
23/30 was my score (theorycally 24 but i don't know why i decide to put answer A in puzzle 11 knowing that was clearly D)
there was a much easier way of solving question 12 all you had to do was see that there were 2 dots and 2 plus signs and one triangle meaning it would be another triangle to make it even
hi, can u please tell how to check if an iq test is actually accurate?how do u judge an iq test?
Hey, its hard to judge if they are accurate or not... Some tests like nicologic, give 100+ IQ for every participant, while in reality, 50% of the participants should get below 100 IQ, meaning that it is clearly inaccurate.
I guess, all you can do is compare your score with different tests. If you get 120 IQ on five different tests, but 170 IQ on one test, then the 170 IQ test is clearly inaccurate.
Oh and maybe check the reputation of the test/people that made the test.
hey man great vid as always. For 27 I get that it is a cancellation, but why isn't it b?
the second image in a row/column is rotated 90 degrees counter clockwise and then added with the first image of that row/column.
in last row: outside plus sign on the left plus nothing -> outside plus sign on the left
in last column: the dot on the bottom is rotated to the right side where it cancels the plus sign on the right -> outside plus sign on the left
@@PuzzlesAndSolutions but this doesn’t hold for the second column where’s it seems to be rotated 90 degrees clockwise and the second row doesn’t seem to follow either clockwise or anti-clockwise 90 degree rotation.
Can you give the interrobang iq test by dr jason betts a go? I'd love to see your take on it and I think it's quite a cool puzzle though I doubt the validity of it lol
I will give it a go after im done eating. I can't make a video about it tho, considering that it is a "pay for feedback" kind of test, at least I don't think I can (would break copyright law).
En la pregunta 23 le suma de arriba a abajo, es decir 2 cruzes mas un rombo = 3 lineas,puede ser la b o e
In No. 19 there is no proof of cancelltion, only an addition, so the answer should be E not F
I think in 29 item is C, if you add the 2 first images and cancel the repeated and mirror verticaly and horizontaly the images then it will give you the third one. Despite that, I've just been able to solve 25 answers of 30 correct in 8 minutes, I wanna solve those late, when a finished the test so, I answered all the same things except the 29 item. What do you think about that solution?
If I can offer an idea. I do not know if its correct but here goes.
I did not manage to solve 29 and 30 within the time limit. But after having a second look, I might have had an idea.
One dot always stays in the same place. while the other dot traveles each of the three remaining spots in the row. If we label the upper dot 1, right dot 2 etc, you have the pattern 2,4,-2,3-2,1.
That means that the answer for the last row is a.
@@gameplayer3050 Yes I gotcha, that could be a posible solution too, I think both of them are correct, what do you think?
@@bdh9904 I think that yours is probably correct. My instinct went with c as well.
Since the way the dots changes only make sense if you look at the broader picture, but move seemingly random when compared with each other, I think that mine is porbably incorrect.
Edit : Just found another way that leads me to a but still think it is wrong. If we look at the figure that has two points opposite to each other and use that as a mirror, each row has one figure, the mirror and the mirror image. Which means that the last one would still be a. I do think however, that it is still wrong.
My idea for this puzzle is this: In each row/column there is one repeating circle.
Row 1: Right
Row 2: Top
Row 3: Bottom
Column 1: Right
Column 2: Bottom
Column 3: Top
-> image (3,3) has one circle in the top and one in the bottom.
Also notice that each row/column also has one circle that moves around the larger circle. In the rows, these moving circles move in clockwise direction while in the columns they move in counter clockwise direction. This pattern also supports that we have one circle in the top and one in the bottom.
Answer A seems correct to me. Personally I think this is overwhelming amount of support for this idea and it is relatively simple -> Enough to conclude it is most likely correct.
I read through you idea of the cancellation and mirroring across vertical/horizontal. It works in the rows and columns and its reasonable to accept it as a correct answer with your explanation along with it BUT it is still more complex than the pattern I described above. Always favour simplicity when it comes to which model to pick. I also see that gameplayer3050 found the same idea as me :)
@@gameplayer3050 Yes, in this kind of puzzles any patter you can find if is reasonable then it might be correct, but mine is a little bit complicated considering time to solve the puzzle, in terms of logic is correct, however, if you wanna solve the entire test maybe the best option would be A.
all correct 30/30 for around 10 minute
I’ve been always afraid of IQ tests because I was always the dumb kid in the class and even though I’m at uni now, I still feel so dumb. I got 23/20 and even though it’s not the best result and I’m not sure what my IQ would be, but at least it’s better than I expected:D
can you explain more about Q25?
Vertical, horizontal, neutral. Top one is neutral, middle one is horizontal, so the bottom one is vertical
Nice
Where we can check standings after we get results?
27/30
23/24 in the 8 minutes
The questions I got different from you were 23, 29 and 30
I found out the logic on 29 and 30 later, but still dont know how could 23 be worng, my answer was B
besides the lines increasing by 1 they were rotating 90° then 45° which would be the square ;-;
Yeah puzzle 23 threw me off, Im still not sure how to explain that one haha
26/30 but it was over 8 minutes i think. Even scrolling is a factor given that You have 16 seconds per answer.
I thought I was being very conservative with my time, but then I slowed up and just was way too slow. I might have been under 8 minutes if I didnt try to explain the puzzles.
@@PuzzlesAndSolutions when one have this amount of qestions in mind than i think the overall score is better. I wnet full instinct in the last 10 or 12, after realising how few of a time i have.
How do you do question 26
sobre cuantos puntos es el test??
I took the test and got 25/30 which corresponds to 135 I.Q., however he said because I am younger than who the test is designed for it is lower than it should be
Hi. Would you mind sharing your age?

Sorry but who said 25/30 corresponds to 135
@@mie360 Olav Hoel Dorum, the man who created the test, when I emailed him my results.
Sorry , i got 30/30 , am a mensa member and only scored 134 on Wais ( administred by a psychologist)
With 23 I got F. With the two plus signs offset you get 4 individual lines. The other 2 examples with plus signs are touching so can be seen as 3 lines. Therefore I took 4 lines to be the answer, and due to their offset nature I determined the pattern in F to be the choice. Anyone know what the actual answer is?
8 minutes did like 25 or 26/30 it was fun, got the harder ones right
I got 29/30 what is my iq in 8 min
0
What is person iq, if it got all correct?
Would have to contact the creator of the test and ask. I might do it soon.
Well
Can you make estimated norms for this test?
hmm, I might. Im pretty sure my esimated norm would deviate significantly from reality tho, so if I did then it would only be a "for fun" score. Id just compare the test with other similiar tests and copy their scoring.
@@PuzzlesAndSolutions The man who created the test has the real norm, it's the same as Mensa Norway test, Wechsler scale with a 15 points standar deviation or (SD15), which means if you get 130, you are in top 2% of population. I knew that because he told me my score and percentile and then I translated the score on internet with a Spanish website about giftedness and the scales were the same.
Acertei 30/30 Qual meu resultado ? De qi ?
Hi which one of Mensa test do you think have almost similar score as the real one
Hmm, its probably best to take the norway one, denmark one and sweden one. The average of the 3 would probably give a good estimate of a real IQ test.
Youre so fast, 25 i think was the hardest
thanks man
For the last question,my answer is C
Can anyone explain for me #27 why not B but C?
Each dot neutralizes the positive.
Does anyone here think this can be trained? I heard IQ is highly genetic, yet it seems trainable when viewing this.
Yeah I think IQ can be trained but probably only to extent but I am not fully sure.
27/30
On 29 can it not be "D" if you rotate the dots on the first row anticlockwise and when they touch the moving dot hits the other and get the 3rd figure, so on the 3rd row from the second figure we can see it is moving clockwise and we get answer "D" ?
Got 26 lol :) but boy that is demanding!
