Ok, so I know this is an old thread but I thought I'd update it, anyway.
I actually went and took the Mensa test! My husband told me to just go do it and the testing price was very low this month so I did.
I missed it by 1 point on the Mensa Admissions Test and their conversion chart put my IQ at around 131, but I need a 132. (There was a second short test that I did worse on. My hypothyroid brain fog started getting to me around section 5 of 7 of the first test and was full force by the second.)
Sucks having gifted "problems", but being on the wrong side of the line.
Anyway, you guys were all right! It didn't actually change anything for me, really. It really doesn't matter if I'm 97th percentile or 98th. I do feel a little relieved knowing where I stand for some reason, though.
It seems I could have or should have qualified for my school's gifted program when I was younger, though.
I'm glad I took it and if you are thinking of taking it (a few told me you were), you should just go for it.
