Tom, I don't recall any study prep that demanded attention to the actual Practice Standard. I downloaded the booklet and probably glanced at it or sought a clarification perhaps on my understanding of the WBS, but overall, it did not play a role in my studying four years ago. Since then, I have seen many study road maps and none of them include the Practice Standard, and I would recommend you use it as a reference, but continue the prep with your other material. If you're averaging 80% by now, you should be ready.
