From a previous job, an IQ test and psych eval was required several different times, so I knew what mine was from several tests. I also had a car wreck and a TBI and it dropped considerably. There were more tests after the accident. However, I was informed that the knowledge is still there but the pathways were destroyed and need to rebuild. That's kinda' interesting, but it was very frustrating at first. I'm still building new roads in my brain!
You can get your results from MENSA. I was a member for awhile, fresh out of HS, but didn't continue on when going to college. There's a pre-test that lasts about 1/2 hour just to determine if you can take the "big" test.
At any given time, to be MENSA material, you have to be in the top 2% of the population when it comes to having an accredited test. There's consistently about 100,000 members worldwide, but that doesn't mean that if you're not in it that you're not MENSA material. It might mean that you don't want to continue paying your dues. LoL! And you want to balance your checkbook with the extra money that you didn't spend on dues.
And I think that all y'all are pretty smart. All triple digits. BTW, I used to have a breakdown of the MENSA people, and they ranged all over the place in their life styles, jobs, etc., including the homeless to millionaires. Smart doesn't always mean wise.
