Three (3) or more letters of recommendation. The graduate school strongly discourages the submission of more than 3 letters, but the math department does not care if you submit more.
Transcripts from all undergraduate institutions you attended, including any exchange student study.
NOTE: You can send in unofficial transcripts with your application, but if accepted you will need to supply official transcripts.
Graduate Record Examination (GRE) scores – the general test is required. The mathematics subject is strongly recommended. Almost all of the applicants we accept will have a subject test score above 50%.
NOTE: GRE scores cannot be more than 5 years old.
For international students, TOEFL exams scores. (see Duke's English language proficiency requirements). The math department only admits students with a TOEFL of 100 or more, and a speaking score of at least 20. TOEFL scores can only be 2 years old at the time the application is submitted. We prefer TOEFL exams but we will accept IELTS scores. To be admitted the score should be 7.5 or higher.
To be eligible for a TOEFL waiver, you must have studied full time for two years or more at a college or university where the sole language of instruction is English and in a country where English is the primary spoken language. The two years of study must be completed prior to application submission.
