I'm surprised you don't know your own IQ score. I couldn't even make it to middle-school without having undergone a battery of at least a half-dozen IQ and aptitude evaluations. By the time I made it out of High School I knew probably more than any person should know about their own intelligence and had a pretty clear idea of the range my IQ would fall into as well as my learning styles, cognitive strengths and weaknesses, perceptual processes, learning disabilities, talents and gifts and aptitude scores on at least 3 standardized exams, and various other cognitive measures.
Where I grew up in Canada we didn't bother with all of that.
The SATs and GREs are the only standardized tests I've taken. And I only took those because I was considering going to US schools.
If you're curious, on the SATs I got 1300. (For the younger people in the audience, the SATs were rescaled, that score was a lot better then than it would be now.) I believe that I'd have done better if I wasn't sick that day. Having to get up between sections to go vomit in the bathroom is not exactly good for your concentration...
It may sound crazy after my previous comment, but I never took the SATs or GREs, GMATs etc. I managed to slip through schooling using a couple loopholes and skip the entrance exams all the way to my M.S.
I had all that same testing, but my parents would not tell me my scores.
PS: I was classified as Exceptionally Gifted / Learning Disabled and I am perfectly happy to leave it as that. In theory I could take another IQ test, but I think I am a little old to focus on my potential. IMO, your potential is only important when you have yet to accomplish anything.
Your parents probably did the right thing. I fretted over my scoring through most of school. It's only now, many years later that I realize how irrelevant those scores are to what I need to do.
The only thing I really wish is that my parents, and the various school administrations had ignored the tests too, because they usually resulted in all kinds of "special programs" that did very little to help me deal with school and adolescence and had negligible impact if any on me when I got older.
And I went to Public School.
