<p>bclintock’s reasoning is very viable.</p>
<p>“Mistaken” reporting aside, 30-50 points really isn’t that big of a deal. There isn’t a huge difference between those scores – the difference between a 1340 and a 1370 is 2 percentile ranks (from 93st to 95th), and there is no difference between a 1560 and a 1510 (they are both in the 99th percentile – everything 1480 and above is in the 99th percentile). Either way you slice it, Chicago’s students are in at least the top 7% of SAT scorers across the nation, so whether there’s a 30-50 point difference in their reporting matters naught.</p>
