The flashcards are terrible, but they do highlight information that the test is likely to focus on. I went through them a few times and if I was unclear about the question or answer, often because of the wording, I would go back and re-read the section it quoted. Otherwise I agree with SteveDave that the practice test is a good gauge of your understanding and it was 1-to-1 with my end score. It's too bad there's only the one.
