<p>If they superscore, the second applicant has a 2400 and in the summary that goes to the decision makers, that is the score they will see. Whether a 2400 is considered significantly better than a 2250 is a different question. Somewhat better, yes.</p>
<p>I think an important question is, realistically, will someone capable of scoring an 800 on any given section drop 150 points on their next exam? It seems unlikely to me.</p>
<p>Despite what some people seem to believe, college admissions is not in general a purely numbers game. There are very few colleges where you get a number for each section of the application, all the numbers are added together, and the person with the highest total number wins.</p>
<p>In your example, a college that superscores will indeed have an SAT score of 2250 for the first person and 2400 for the second. But they will also see that the second person had rather inconsistent performance, which may well also affect the decision. I just don’t think that you can categorically say “yes, one person will be better”.</p>
