I had the same thought. As soon as you recognize that there are only a handful of categories of patterns, recognizing the solution is just a matter of matching your question against a known pattern (e.g. this row rotates, you combine the two shapes to produce a third, this shape moves and this one doesn't, etc) Taking a few of these over and over would quickly attune you to what to look for. I suppose in a perfect world, you'd be able to generate a test with tricks the participant hadn't seen before to test how quickly a person could cultivate a list of patterns to check each question against.
