As I understand it, they convert all test scores to ACT scores over a two year period. My DD got nominated scoring a 1520 and a 35 (36/35/35/35). However, she did not miss a question in the math section of the SAT and did not miss a question in the English section of the ACT. GPA is only a 3.75 and I’m not sure that really makes a difference until entrance to the semi-finalist level.
