>>11886412This is why IQ tests aren't that useful. If you can get tests with completely different questions but still always improve based on performance on past tests, then it's not a reliable score of anything fundamentally inherent to you.
It's probably better called a "cognition score" or "cognitive performance score". It's not a measure of one's baked-in "intelligence" and instead just measures how good they are at performing certain cognitive tasks at that moment in time. It can be influenced by practice, age, drug consumption, amount of sleep, etc.
