How do I think?
IQ and Cognitive Ability Tests.
These tests measure reasoning ability with classic puzzle formats - matrices, series, analogies, mental rotation - scored on the standard IQ scale and compared against adult results. The general test samples four domains for a broad estimate of cognitive ability; the specialized tests go deep on a single domain.
Scores are capped at 160 because that is where honest online measurement ends. If a test offers you 200, it is entertainment.
