What two letters designate a test to measure intelligence?

in 1970s Koko the gorilla was measured with IQ of 80.3. that's a higher IQ than many humans.

All it measures is your ability to do the sorts of puzzles that you get in IQ tests. I should know - mine is _supposed_ to be freakishly high and I am no genius. And I was in Mensa for 25 years, where I never saw any examples of special brilliance. Just a lot of nerdy people, keen on computers.

Mine is 180

I'm not good at letters
