<p>What is hard to do is obtain the lowest raw score possible, which on math is -11: you have to get every multiple choice question wrong.</p>
<p>@pi: the lowest scaled score (for the SAT, 200) is roughly mapped to the “by-chance” raw score (for the SAT, 0), and scores below are truncated to the lowest scaled score. A score of 200 is always there, as well as 800, even in the cases when the equating process resulted in a perfect raw score mapping to a score less than 800 (this happened before the 1994 scale change).</p>
