<p>Can someone elucidate the whole 25th and 75th percentile score stuff?</p>
<p>Basically, it's the middle 50% scores of students accepted at a college. For example, X University has 25/75 of 1100/1300. 25% of the accepted students will have scores higher than 1300, and 25 % of the accepted students will have scores lower than 1100.</p>
