What is Extreme?
Extreme is an exclusive super High IQ society open to those in the top 0.0031% (at least 160 iq sd 15, 164 iq sd 16) of the unselected adult population. Mensa accepts those who score in the top 2% of the unselected adult population or 1 in 50, you can think of Extreme as some kind of a hyper Mensa (I wouldn't use this name due to copyright) that accepts 1 in 31.560.
Interesting, how can I join?
Information about joining can be found in the Admission tab.
Wait a minute, it's a High IQ society and you are using google sites?
Haha, that's right, the reasons for this is that the website : a) is free, b) easy to make and c) I wont have to register for a domain every year and risk that it may get down and replaced by something shady like it has happened to the websites of older IQ societies who are inactive now.
Do you offer certificates?
Soon I will.
Who made this High IQ Society?
See the founder tab, it's Petros Gkionis.
