The thing is, and I'm referring to when the exam was just the SAT and not the SAT I, that historically there were a bunch of words that were highly prominent in the verbal sections.
Having that vocabulary neither means you're actually learned, or particularly well-versed in English. It just meant that you had memorized a bunch of SAT words that kept on showing up on the exam.
And like I said, Word Smart (and a later Word Smart 2) were a great compilation of this vocabulary. And others have mentioned similar titles. Whether those titles are still relevant is beyond me.
So if your objective was to develop a vocabulary to maximize your score in the verbal section, rote memorization was a much better/faster way than to actually read literature.
