This was helpful in that it describes some of the strategies used by test preparers to invent questions. For instance, in the 'how are these words alike' type questions, I always thought about MEANINGS of words, like the SAT-type thinker I am. But there are other ways the word problems are designed - for instance, simply by the length of the word, or the position of the vowels. Those sorts of analogies never even occurred to me to think about. Worth its reasonable price.
