I took a Mensa test years ago. Got 26/25... couldn't get one and got 2 extra points for finishing before the time limit.
They said "Welcome, Brother", but I never joined. Collectively, they were too weird. Much rather hang out at the tennis court and drink beer.![]()
That 25 question test sounds like the sample or practice test, rather than the standardized tests Mensa now uses (and have always used, AFAIK). Though Mensa does allow certain previous evidence to qualify new members for admission. For instance, my ACT was allowed (but I missed by one stinkin point!). At my testing session, I had to pay for the two standardized tests, and squeaked in right at the 98% level (one test said an IQ of 138 and the other 142). The neat thing about Mensa is you only have to be smart once.
Mensa is composed of practically independent geographically determined chapters. I joined SouthEast Michigan Mensa and we drank a great deal of beer - SEMM is a very good chapter. Then I moved to NC (USA), I dropped out of Mensa - the chapter here is very different than SEMM.
This post turned out to ramble more than I intended, but I did want to say that different chapters will be different. Just because nobody in one chapter gets drunk, doesn't mean anybody in the chapter by you is sober.
