confused about the blue book..

<p>Quick question...it's late, and I know I must be making some kind of stupid misunderstanding...but I'm sitting here, taking the practice test on CB's official SAT guide...and I can't find Section 4 anywhere...yet there's a section for it on the answer sheets.</p>

<p>Where did it go? Am I just being stupid?</p>

<p>It's an experimental section-the practice tests don't include them.</p>
