Where your score puts you
- Below 1240: lower than three quarters of enrolled students. A retake has the most upside here, and at a test-optional school you can also leave the score off.
- 1240 to 1430: in line with the class. The rest of your application decides it.
- Above 1430: higher than three quarters of enrolled students. Testing is no longer what holds the application back.
