<p>Hmm...well would a half-black, half-hispanic student get double the advantage of a black student? Half minority, double minority, I don't think it matters: they're both minorities.</p>
<p>It all depends on what that person would check. If know of part white part asian people with American last names who opt not to check that. Also, I know of a Spanish Jew who only checked spanish. </p>
<p>If I would have to give an answer, i think student A has the advantage.</p>
