Here's how this test was scored:
You were given one point for each correct answer.
One bonus point was added to your score if you completed the test in less than 25 minutes,
two points were added if you finished in less than 21 minutes,
and three points were added if you finished in less than 18 minutes.
If you scored:
23 - 18 points: You are exceptionally intelligent -- a perfect candidate for Mensa.
17 - 16 points: Your I.Q. should be in the higher percentiles of the population -- potential Mensa material.
15 - 14 points: Above average. You might want to try Mensa.
13 - 0 points: Mensa may not be for you, but don't worry about it.
Some people don't do well on quizzes, but do very well in real life.

12. Complete this analogy:
13. All of my grandchildren are under 17.
All of my granddaughters are beautiful.
All of my grandchildren have red hair and blue eyes.
My oldest grandchild has long red hair.
The legal voting age is 18.
Which statement can be proved by the information given?
(A) My oldest grandchild may not yet vote.
(B) My oldest grandchild is a beautiful girl.
(C) My youngest grandchild may not yet drive legally.
(D) My youngest grandchild has short red hair.
All of the others may or may not be true, but you cannot tell from the information given. The oldest grandchild could be a boy, for example.

15. A snail is climbing out of a well.
The well is 20 feet deep.
Every day the snail climbs up 3 feet and every night he slips back two feet.

16. On your bookshelf you have 3 books in a set, Volumes I, II, and III, in the usual order from left to right.
You also have a bookworm who is eating them up.
The pages of each are two inches thick; the covers are each a half-inch thick.
If the bookworm starts at the outside of the front cover of Volume I and
eats through to the last page of Volume III, how many inches has he bored through?
Put a set of books on the shelf and look at them.
If the worm started at the front cover of Volume I and ate through Volume II, he would not have touched the pages of Volume I at all.
Volume II, with cover, would be three inches, and the worm would eat only the back cover of Volume III, another half-inch.
17. Six thousand, six hundred, six dollars is written $6606.
Now write eleven thousand, eleven hundred, eleven in figures
as fast as you can.
18. A woman collects antique snuff boxes.
She bought two, but found herself short of money and had to sell them quickly.
She sold them for $600 each.
On one she made 20 percent, and on the other she lost 20 percent.
Did she make or lose money on the whole deal? And how much?
From the facts given, one cost her $500 and one cost her $750.
So, she paid $1250 for them and sold them for $1200, losing $50.
19. Complete this analogy:
Figures are reversed and color is deleted.

(c) The expedition chief was not interested in coins.
(d) There was no way to make coins before Christ.
Certainly no coins were minted indicating an era marked by someone who had not yet been born!
Here is an email that I received from Matt McCracken regarding some of the ambiguous questions on this test, and I think he makes some valid points:
I thought I'd provide some brief feedback on one of the tests on your web page. I know you aren't the author of the test, but nevertheless I feel compelled to comment since you've published it.
Regarding Mensa Test #5:
Question 4: "Odd one out" questions are always frustrating because they have multiple correct answers. There is no empirical way to know which is more correct than the others, and therefore it requires guessing. With this one, for example:
* Miami is the only one without an "o" in it.
* Copenhagen is the only one that's not 3 syllables.
* Chicago is the only one that doesn't repeat a 2-letter sequence.
* Etc.
Question 8: This relies on trivial knowledge rather than on raw intelligence. It's not ideal for Mensa tests since it's luck-based and illustrative of nothing about a person's actual IQ.
Question 11: You could serve any of those combinations and everyone would be able to eat something. The correct answer should be "E". If everyone needs to be able to eat everything, that should be clarified in the question. As written it's an "any", not an "all".
Question 14: While it's true the banana plant is not technically a tree by botanical classification, it would be *extremely* nit-picky to expect the average test taker to know this since the plant functions for all intents and purposes as a tree. Also, you have to unwrap bananas to eat them, as with peanuts. You don't have to unwrap peaches.
Anyhow, sorry if this comes across as obnoxious. I'm just passionate about making IQ tests as unambiguous as possible since it's very frustrating to answer a question correctly but still get the question wrong. Hopefully it's feedback you can put to constructive use!
