<p>How is a 3.55 GPA near the top of your class? Does your school grade unusually harshly? I think that would be key determinant as to your success in admissions. Also, I know that Duke’s policy is to not give extended time to any student (unless a specific professor decides to do so for a given student, then that’s his/her decision). Not saying that hurts your chances, but perhaps they look negatively upon that (not sure though). But an upward trend in GPA is always positive. Your SAT scores certainly make you a competitive applicant and legacy obviously helps. I personally think Duke is a reach for you, but you never know, especially if you have a compelling essay. ED+legacy boost is probably vital; I’d think your chances in RD would be much worse. Good luck.</p>
