I really enjoyed my Duke Days experience. On top of the school's great reputation, the knowledgeable and accessible professors, small clinical groups, a high NCLEX pass rate, state-of-the-art technology and facilities, and the option to go on a global excursion were just some of a number of things that make the program appealing. The campus itself is also beautiful!
The only unappealing part is the price tag, but if you ask me, the program (and all of the resources and opportunities that it provides) is well worth the cost.
To answer your other question: I didn't encounter any big surprises that I wasn't expecting. Overall, Duke left a great impression on me, and I am thrilled to be attending!
