You, my friend, are profoundly gifted, especially if you scored that high as an adult. That said, it only describes how your brain works, it doesn't describe how high achieving you will be. That is an amalgamation of all your life experiences and things like opportunity, perseverance, etc. The tools you have to understand complex things are much wider than a regular person, but it doesn't mean a regular person can't outhustle you. I don't know how old you are, but it's never to late to dust off your tools and give it a go at something more aspirational, if that's something you've always wanted to do. If you're happy as you are, then there's no point because happiness is what really matters in the end.
To be fair, I knew I would be taking the test well in advance, so I took dozens and dozens of practice tests over the course of two weeks. They like to say you can’t study for an IQ test but you can.
I like to think I’m pretty clever, but I almost certainly would not have gotten 160 if I hadn’t gotten the practice test.
Sorry, I meant to add more but got distracted and I can't edit now.
I'm in my mid 30's. I'm happy enough where I am now; my biggest issue has historically been focus and apathy more than understanding concepts, much to the frustration of my teachers in high school. I was that frustrating kid who clearly understood the concepts perfectly fine, and was even fairly active during class, but I wouldn't do my homework so the teachers would be forced to give me bad grades.
I obviously don't blame the teachers for this, they're doing what they have to, but I do sometimes think that the system is a bit too one-size-fits-all, even still. I took advanced classes in high school, I got very high ACT scores (36 in English, 34 in math), but I still have always had middling academic performance because the teachers would be stuck giving me crappy grades.
For reasons slightly involving skill but mostly involving luck, I managed to cobble together a successful software career even after dropping out of college the first time around, worked without a degree for almost a decade, and eventually worked as a practicing software engineer at the senior level at BigCos. I have a bachelors now, and even a masters, and some graduate PhD work (though I didn't finish that, too time consuming while working full time), but these all came after I had established a decent career.
I think that being a little clever [1] certainly helped me through this, but what I think helped me more than anything was the fact that a) I had a geeky hobby of learning how to program when I was fourteen or fifteen that never really went away and that I was able to fall back on and b) dropping out in 2012, which just happened to be the year that pretty much everyone got a smartphone and consequently there was a huge demand for programmers and they were willing to overlook a lack of credentials.
My life has turned out fine; not perfect but certainly better than most people on this planet or even this country so it's hardly worth complaining over. I do wish I had taken school more seriously as a teenager because then I would likely be able to have move into a more mathy-theory-based role, which I seem to be unable to do as of right now [2]; it feels like I'm playing a game of catchup, which isn't impossible but it definitely is harder than if I were able to focus on school full time.
Dunno why I decided to dump my life story at you. Just one of those days I guess.
[1] Though as I said in the sibling comment, probably not nearly as clever as the tested IQ suggests.
[2] No matter how many I apply to, it seems. It doesn't help that every researchey role now is for AI/ML theory which is cool but pretty far from my expertise or the kinds of math I've studied or have any expertise on.
