<p>How realistic are the questions in Kaplan's 12 Practice Tests? I'm asking because my scores from the official SAT book and my scores from the Kaplan book are REALLY different. It's not just the scores, it's the number of questions I'm getting wrong. Is Kaplan's supposed to be harder? Also, besides the official SAT book, which books have the "best" practice problems?</p>
<p>actually, the question is mostly directed towards the writing portion...</p>
