<p>Where is a good place to ask about specific SAT questions from the blue SAT official guide, other SAT prep books, and from previous tests?</p>

<p>For example:</p>

<p>On the sat official guide blue book on page X on question number Y, why is the answer A? Why does so-and-so's line 30-31 mean that [blah].</p>

<ul>
<li>The blue book does not have explanations for the questions</li>
</ul>
