Hi guys! It’s Janice, welcome back! If thisis your first time here, this channel is called Sharp Cookie, and I do all sortsof things related to learning, studying, test taking, problem-solving, all of thatfun stuff! And I’m a tutor. I’ve been tutoring for about five years.I have many hours of tutoring experience, all different types of subjects, andtoday we’re going to be talking about the Mensa IQ test practice test. Now youcan find this test on the Mensa international website, and I’m gonna linkthat up below so that you can easily find it. I’m also going to show you howyou can google it and get to that practice test because it’s free! Sounlike a lot of IQ practice tests that I found online, that are either really notthat good or they make you pay either to take it or to get some kind of results,this practice test you can do online. It’s not timed, although you can timeyourself if you want, and it’ll also tell you which problems you got right andwrong. So I thought today we would go through the practice test together. I’mnot going to go through every single problem because a lot of these problemsaren’t even teachable, so I’m going to really focus on problems that I thinkare teachable. And whether you want to take the Mensa IQ test or not, it’sjust fun to do some IQ test problems, so that’s what we’re doing today! If youhaven’t seen any of my other videos yet, I’ve made another video on when Iactually took the Mensa IQ test, so I go through the types of problems I saw, whatI expected, what I didn’t expect, and I also have another video that I filmedafterwards where I give you my results, and I show you the exact email, and Itell you like what what types of scores they show you, and I explain thepercentiles. So go ahead and watch those videos after this one. Okay so what I’mdoing now is I’m googling “Mensa IQ test,” and it’s the first option that comes up.It’s called the “Workout,” and if you read the instructions theyrecommend that you take this test in about 30 minutes, so take that as youlike. Because I’m explaining it, we’re going to take a little longer per problemthan you normally would. Okay so this first problem is aboutpattern finding with numbers. Now if you have a lot of experience with numbers,this will probably be very easy for you. And if you don’t, it will probably beimpossible. So I would categorize this problem as something that is not reallyteachable. Now can you learn it and spend a lot of time on math problems andgetting a better number sense, which is your comfort and ability with numbersand pattern finding? Yes! Is that going to happen in a two minute explanation fromme? No. This sort of thing you develop over time with doing a lot of problems.So this first one for some people might be obvious. It’s 1,600 because it’s oneof the perfect squares. So Sally likes all perfect squares. Now again, you eithersaw that pattern or you didn’t, so I’m
all perfect squares. Now again, you eithersaw that pattern or you didn’t, so I’m going to go to the next one. Okay this next problem I do want toexplain. It is teachable. So if two typists can type two pages in twominutes, how many typists will it take to type 18pages in six minutes? So this is your classic rate problem. What you want tofigure out is what one person can do. In this case, if two typists type two pages intwo minutes, that means one person can type a page every two minutes. And if youcome to that conclusion, you can pretty easily figure out the rest. So they wantto know how many can type 18 pages in six minutes? Well one person, if they’retyping one every two minutes, in six minutes they’ll get to three, so18 divided by 3 is 6, so I’m going to need 6 typists. What is the number that is one half ofone quarter of one tenth of four hundred? So this is another one that with alittle bit of math practice is not that hard to do. When you’re dealing withfractions and percents like this, you just want to multiply them all. Andbecause it’s multiplication, order doesn’t matter. So what I would do iswrite out 1/2, times one quarter (which is 1/4), times 1/10, times 400. So you can do thisstep by step in your head, and say okay what is one tenth of 400? Well I move the decimalplace over one so that’s 40, and then I need 1/4 of that so that’s 10, and then Ineed one half of that so the answer would be five. If you count from 1 to 100how many 7’s will pass along the way? I’m going to skip this one. Again there’s notmuch to explain. They’re two men starting at the same point, walk in oppositedirections for 4 meters, turn left walk another 3 meters, what is the distancebetween them? Again if you’re good with numbers, this is going to be very obvious.It’s one of the most common right triangles. It’s called the “3-4-5 RightTriangle.” It’s one of the Pythagorean triples. And so I know that my hypotenuseof this triangle is a 5. So if one leg is the 3, one leg is the 4, the hypotenuseis a 5. So because the two people are both going away from each other, it wouldbe double that. It would actually be two hypotenuses of a triangle, and that wouldmean it would be 10. Okay then we have a few where we have tounderstand what a proverb means. This favors native English speakers forsure. If you’re not a native English speaker, these are pretty much impossible.So they ask you “Birds of a feather flock together,” what does this mean? So firstwhat I like to do as far as strategy is I always put something in my own words,which solidifies my comprehension of what I’m doing. So in my own words birdsof a feather flock together: it means that similar people tend to get drawn toeach other and spend the most time
that similar people tend to get drawn toeach other and spend the most time together. So then when I look at this, “aman is known by the company he keeps” is the closest one to my summary or myprediction. Okay this is very similar to the last one. Again, I read it. I come upwith what I think it means in my own words, and then I look at the answerchoices and try to find the closest one to my prediction. So “Don’t count yourchickens until they’re hatched,” in my own words, that would mean don’t count on acertain outcome until it actually happens, and then this one about notrelying on something until it actually happens is the closest to my prediction.Which vowel comes midway between J and T? There’s no strategy to this. If you knowyour alphabet, you can figure that out, so I’m just gonna skip that one. Okaythis next one is very common on what I actually saw in the real Mensa test, andthis is an abstract puzzle where they give you a series of shapes, and they askyou what shape would come after. And you have to diagnose what the pattern is. Soagain I try to verbalize in my head the pattern. So I have two circles and thecolors are reversing, so I would expect a .hexagon with the colors reversed And then we have another number onewhere we’re looking at numbers in a series. Now right away I noticed thattypically with numbers in a series, the numbers tend to go up as you goalong, and if they don’t do that, where they’re kind of erratic, usually thepattern has to do with looking at every other number. So that’s just a littlehint. That’s what I’ve noticed with series where they kind of go up and down,up and down, then up and down, instead of that incline that you usually see withthis series. So here if I look at every other one, I’m looking at odds 1, 3, 5,7, 9, so the next one would be 11. And then here 10, 9, 8, 7, 6, so the next would be 5.So 11 5. So again the hint is when you’re seeing like erratic numbers going updown, up down, look at every other one. Here we have another visual one aboutcompleting the series, so I like to look at the elements separately on thesepuzzles. So what I’m noticing is, for example, the diagonal line it goes fromleft to right, upper right, lower left, upper right, lower left, so I would expectthe next one to probably be on the upper right, which leaves me with these twooptions. Now I look at the other lines and what pattern is happening so one, two,three, four, five, at the top. Two at the top. Three at the top. Four at the top. One.So I’m not seeing a pattern right away. At the bottom, I have one, four, three. Theyalways equal to six. Okay what’s happening here is I’m seeinga 1 of 3 and a 5 skipping and here 4 to 5, 3, 1, and a 2, 4 again. So what that tellsme is I’m probably going to have a zero, so I’m gonna say it’s this one. We haveanother series. In this series we’re just
brain teasers for kids I’m gonna say it’s this one. We haveanother series. In this series we’re just
I’m gonna say it’s this one. We haveanother series. In this series we’re just increasing, so you don’t need to thinkabout the strategy of skipping numbers. 2 3 5 7 11 13. This is another one where Ijust see it right away because I do a lot of math, and I tutor math, so to meit’s obvious that these are all prime numbers and that the next one is 17, but again,this is not teachable. You either do a lot of work with math and you know it oryou don’t. I would say that when I do have those series, I also look forpatterns. So are they all even? Are they all odd? Are they increasing by smallamounts, big amounts, erratic amounts? And that helps me deduce where the pattern is.Okay series of letters in this one. Again I’m seeing where letters tend torepeat themselves, so that’s something else that you can take away with you.Look at when the letters repeat. BAC then BDC then EDF, so these two D’s arerepeating. These two B’s are repeating. The C’s are repeating. Okay again becauseit’s erratic, make sure you check that trick of looking at every other one, andthis is that case because you have B, C, D, E, F leapfrogging. Really A, B, C, D,so the next one would be E. Okay this one’s a little bit hard to seebecause you need to be able to tell if those lines are connected to the petalor not, and I’m gonna skip this one. Okay, this one’s neat. We have a series, but themiddle one is missing. Okay again this is another one that’s very obviousto me, but I’m increasing a lot, so when I see the numbers increasing a lot, my mindimmediately thinks about exponential growth. So I’m thinking about squares orcubes, and right away I can tell this is cubes. So this is one cubed, two cubed, threecubed, and the next one would be 4 cubed, which would be 4 times 4 which is 16. And then16 times 4, which is 64. Here again they want you to find themissing number. This one is increasing. It does get bigger as you go along. Theother thing I’m noticing is we have two repeated 1’s, and when I see increasingpatterns, another thing I look at is if something happens withthe terms before it. Either they’re added or multiplied, and in this case they’readded. So 0 + 1 is 1. 1 + 1 is 2. 1 + 2 is 3. 3 + 2 is 5. 5 + 3 is 8. 8 + 5 is 13.13 + 8 is 21. I’m gonna skip these scrambled words. I’m not very good atthese to begin with, and quite honestly I find them very difficult, and I’m notsure what the strategy would be here other than you’re trying to matchletters that are commonly found near each other. So again this would favorpeople who read a lot, native English speakers, and people who are great atspelling. Okay they want to know what the word is coiled around. This one’s alittle easier because you at least know the letters are in the right order. They’re actually not in the right orderbecause I’m seeing “stronger.”
They’re actually not in the right orderbecause I’m seeing “stronger.” I’m going to skip #19. You can just countthose up. Not much to say about this one. I’m gonna skip 20, but when I look at theanswer choices this is a strategy you can use on the test. Estimation would begreat because besides 25 and 28, all the answer choices are very spread apart, sowhen I see that I know that estimating is the way to go, especially when youonly have like a minute per problem on this test. If a circle is one, how many is anoctagon? Eight because it has eight sides, eight lines, and a circle is just oneline. I’m gonna skip a few here. Okay 23 is really fun. I actually enjoy these!I post these in my Facebook group and on Instagram a lot. I just find them a lotof fun. They’re not that hard to figure out. For example I start with the toprow is an obvious one to start with because you have all the same fruit. Youhave the apple equaling 28, so then you know if you do 28 divided by 4, the applewould be 7. Then you can figure out the next row, 2 apples that’s 14. 30 minus 14,that’s 16, divided by 2. The banana is 8. So I’m just gonna write this down, soapple is 7 banana is 8. Ok then it starts getting tricky because you have two rowswith two equations, so you might need to do a little bit of algebra here, where wehave one apple, one banana, so that would be 15. You have five left,so I know cherry + strawberry equals five. And then the bottom row, I know thattwo strawberries + one cherry equals eight, and then I do a little bit of algebra. Okay the strawberry is equal to three,which means our cherry is equal to two. So then I have 2 apples, 14, plus a banana22, plus a strawberry 3, so my answer is 25 for that one. Here’s a logic problem. There are 1,200elephants in a herd. Some have pink and green stripes, some are all pink, some areall blue. One-third are pure pink. Is it true that 400 elephants are definitelyblue? All we know is that 400 are pink, butthey don’t tell us anything about the ones that are pink and green or the onesthat are all blue, so I’m gonna say “no.” Just skip 25, skip 26. These are more wordproblems. Number 29. So I actually saw this one onthe test except it was in visual form where they would have like a series ofmaybe five or six pictures, and you had to decide which one didn’t belong. So inthis case the flower doesn’t belong because it’s natural and the others areman-made art. Last problem. Pear is to apple as potato is to? So pear and appleare both fruits, so I’m probably looking for another vegetable, so we’re gonna gowith radish, and we’re done! So that’s it for today. If you’d like to join my Facebookgroup or find me on Instagram and do puzzles along with the rest of us,please join us, it’s a lot of fun. I also do virtual online tutoring, so if youwant to learn about that you can email me at firstname.lastname@example.org.Again be sure to watch the other videos about Mensa, especially if you’rethinking about taking the test soon. All right, thank you so much for watching!If you found the video helpful, please “like” it. Also consider subscribing. I post newvideos every week. Thanks so much for watching! I’m Janice, bye!
