The people who do and end up passing the courses at that age are typically in MENSA (society for people with extremely high IQ’s like 150 points at their age – you have to take an IQ test and get that score to join and you have to pay membership fees…).
Where did you get that information? Totally not correct.
To qualify for membership in Mensa one needs an IQ at or above the 98th percentile. The actual number (150 in your example) varies depending on the test.
And if you’ve ever taken an IQ test, you can submit the score and there is no need to take another test.
Some qualifying scores, as noted on their web site, are:
Cognitive Abilities Test (CogAT) Composite SAS of 132
Differential Ability Scales (DAS) GCA 132
Otis Lennon School Abilities Test (OLSAT) Total SAI 132
Otis-Gamma Test IQ 131
Naglieri Nonverbal Ability Test (NNAT)
Individual and Multilevel Forms Nonverbal Ability Index Score of 130 or above
Naglieri Nonverbal Ability Test 2 (NNAT)
Individual and Multilevel Forms Nonverbal Ability Index Score of 132 or above
Stanford Binet IQ 132
Stanford Binet 5 IQ 130
Woodcock-Johnson Test of Cognitive Abilities
(not the Woodcock Johnson Achievement Test) IQ 132
There are other tests listed, also, such as SAT, ACT, LSAT, GRE, etc. And by the way, the number “150” is not to be found anywhere.
And where did you get the idea that people with high IQs are “typically in Mensa”?
The current population of the U.S. is more than 311,000,000 people. Two per cent qualify for Mensa. That would be 6,220,000. Since the current membership of American Mensa is approximately 56,000, people with high IQs typically ARE NOT in Mensa.
