All my IQ scores throughout the years were within a few points of each other. I don't recall "book smart" questions. However, I do recall a lot of problem solving questions. Like, most of them seemed to be problem solving questions. Oh well, don't take it from me. I mean, I only took probably six or seven IQ tests in a controlled environment, as a child, and I probably don't remember them all that well.
IQ tests are more about pattern recognition, and the ability to discern and compare relationships between objects, etc.
There should be anything like 'factual or general knowledge' questions, as those speak more to exposure and retention of information than intelligence.
(IQ tests aren't great at measuring intelligence anyway, but still...)
