<p>PC: most folks I know consider the the SAT-ACT concordance table as a 30 point =/- range relative to the ACT, particularly bcos the ACT rounds up: a 32 score includes everything from a 31.5 to a 32.25. Thus the 20 point differential you mention is not statistically significant. They had to draw the line somewhere. As I said earlier, close enuf for government work.</p>
