<p>I've been getting a lower score than I'd expected (690,700,710).</p>
<p>Are they accurate or do they underestimate scores?</p>
<p>In my opinion, I think Sparknotes overestimates your score</p>
<p>I scored ~740s on the sparknotes US history tests, and I got an 800 on the actual thing. I would make sure to take the actual CollegeBoard practice tests for US History, in addition.</p>
