<p>bovertine - I’m not sure how to deal with the Brown data.
There are roughly equal numbers of ACT and SAT takers.
There are about as many ACT scorers of 33 and above as there are SAT scores of 2200 and above.
Considerable more accepted students are SAT takers.
Ratio of ACT perfect scorers applying to ACT 33-35 scorers applying: 3/100
Ratio of SAT perfect scorers (single section) to SAT scorers in the 750-790 section: 25/100 (roughly , averaged over the three sections)
So, like, you , I give up. I’m just not sure what it means.
(There is no info on dual-takers that I can easily find.)</p>
