10 points is a standard deviation. so an IQ of 130 is already in the top 1%.

I think the SD in a typical IQ test is 15 or 16. My IQ is in the low 160s, and I'm pretty sure I'm around sigma 4.

that may have changed with the time. initially, meaning when they were first created, they were setup to have a mean of 100 and SD of 10, for the obvious reason of making it very easy to do calculations. i noticed most 'test yourself' or online iq test have much much wider SD which i think is only natural because they are being marketed to the masses and you much rather sell them a test that will give them a big number than a low one.

True. A friend of mine took an online IQ test once and scored 169. Then I took it myself and scored... 169. Needless to say, I was suspicious. So I took it again, answering every question wrong, and I got... 169. I'd be surprised to find an honorable IQ test anywhere on the internet.

Yea online ones like this are either straight up scams or set the ceiling way too high for the insanely idiotic questions they ask... suprisingly enough, lots of people can alphabetize 4 words by their first letters, yet these are questions online. To the person who asked how I had mine scored; Stanford-Binet, as well as a couple others when I was young that I dont remember.
I obviously tested into mensa, but only bothered with it for a year... it was a bunch of old people who went out for lunch once a month
below is a pretty good link to some online IQ tests that are normed by people with real intelligence and ability, not companies who want to sell you something... I think I scored a 170 on one of cooijmans' tests, but they are normed with the ceiling a little too high I think.
