True IQ tests cannot be studdied for.
See a pile of blocks, and count them. But you must imagine the blocks behind them, holding up the blocks that you see.
Can't be faked, or studied for.
Either you have 3-d skills or you don't.
I did get a cou;le of dings, though. The test procter asked what is common between a foot and a pound. I answered that the basic units were divisible by four.
He said that the "correct" answer was that they were both units of measurement.
I said, "Duh."
Then he asked me to draw a man.
I respectfully disagree. Say, I failed because I didn't visualize behind the blocks. I learn. The next time I will remember and score higher:')
