I have always wondered how do they say IQ tests can't be gamed or learned, but I never believed that. There really must be certain number of standard pattern matching ways that can be applied. Just cram these like leetcode and you should get better.

This, specially the pattern matching. Sequences, dominoes, there's not many ways they can be arranged. The first time people see them they will be stumped, but after knowing how they're made, the tested can figure how the testers think and answer them easily.

Another example is language and vocabulary, which are heavily influenced by culture and education. If IQ is going to measure education too, it would be valid to include number sequences that are the even digits if Euler's number, or names of famous astronomers without the vowels.
