Scored a total ceiling score of IQ 160+ sd15 (164+ sd16) on WISC-R at age 7 and one month,
a result that by her own account the Psychologist who tested me
had never seen in practice in 20+ years of her career by that time.
However, I refused skipping any grades,
even though I was told that theoretically I should skip more than four.
Since then, I have taken three more professional standardized
tests, scoring between IQ 161 sd16 and IQ 167 sd16 on them.
Since these are all at the very end level of meaningful statistical measurement they leave an open question on the final value. One way of trying to get around this ceiling limitation would be by applying the method of variance of sums on these scores which leads to an indicated total rarity IQ of 171-173 sd16. However, the only safe claim is that of the lowest possible value, which is in the mid 160's sd16 (99.997th %-ile+).
