只申请MERIT, 不用填CSS。
Duke University offers a limited number of merit scholarships. Applicants are automatically considered for Duke merit scholarships by virtue of their admissions application. Of course, we encourage all prospective students to complete the FAFSA and CSS Profile applications to ensure consideration for need-based funds, but no aid application is necessary to receive merit-based scholarships.
