<p>How many schools use the super score (taking the highest subscores, even from seperate sittings) and how much weight is there in them. I have heard varying accounts.</p>
<p>Many many schools superscore the SAT and a few superscore the ACT. Check the websites of the schools you are interested in, to see if it indicates that they do. Otherwise call admissions and ask. What do you mean “how much weight…?”</p>
