Take the test on a different day, or sleep more beforehand, or do a different test, and your IQ will change.
Not as much as people think. We’re talking around 5 points of difference - 10 at max. Broadly speaking, the results of a well-designed test are highly consistent over a long period of time as long as it’s measured under similar conditions. It’s among the most repeatable tests in all of psychology.

IQ is not useful as a measure of intelligence, even on a mass scale. It is fundamentally bullshit
