SAT Subject Tests

On the list for admission requirements to Northwestern it says recommended SAT subject tests. Does that mean they’re basically required? I’m looking to get into McCormick.

From an earlier post - No, SAT IIs are NOT required:
My son called NU admissions … was told that SAT IIs were for those students that wanted to show a competency in an area that grades and other testing did not reveal.

Since S had 4.0 GPA and all 5s on his APs he did not take any SAT IIs and was an ED Admit.
