Applicants applying ED at NU have a huge advantage over RD applicants. As a targeted minority, I would estimate your chances at 75% ED and 50% RD. NU typically selects RD applicants with ACT scores of 33 and above and/or a combined SAT score of 2150 or better. Even as an ED applicant try to boost your test score to 31 or above on ACT and above 2000 on SAT. Note: It appears NU gives preference to SAT.
