The campus is beautiful, the students sharp yet not cutthroat, and the curriculum different and intriguing. Also Duke grads have lower debt, on average, than grads from even state med schools.
What impressed you negatively?
Hotel access in the area is spotty. Reserve early.
What did you wish you had known ahead of time?
That the 3rd year can be, and often is, used for pursuing a second degree: JD, MPH, MA, MBA etc.
