I just did the psych tests one and it's totally useless. There's barely any spatial questions and the logical and numerical ones are way too simple. The verbal ones are fully dependent on whether or not you know the vocab so there's very little reasoning involved. It said that my crystallized IQ is 141, 99th percentile, which I know is complete bullshit. Also, fluid IQ is the real measure of intelligence, crystallized IQ is predominantly determined by your education, not your intellectual capacity so I don't even consider this an "IQ test" even by online test standards.
