1. Yes there are definitely summer classes. Fall, Spring, Summer, Fall
2. ALL ABSN classes are on campus with the exception of Statistics that I know of so far. The master's program is on/off campus.
3. Not personally worried about getting a job with Duke health after graduation. I'm actually going to the Navy so that's not my concern, BUT it really depends on how your preceptorship goes as well as your relationship with your advisor + recommendations so keep that in mind.
4. I'm a first semester fall 2011 student and all I can say is: PERSEVERE! The process can be daunting at times and all the waiting can drive you insane but if you meet all of Duke's min. requirements, take solace in knowing you've done the best you can do. Don't hesitate to ask questions, and DO go to Duke Days if you can. It really gives you a glimpse of what the program is about and gives you a good idea of how you might fit in. Talk to current students, we really want to help you. Above all, best of luck and allnurses helped me when I was going through this process.
