I am sorry I just saw your reply.
Have you heard back from Duke/POI? Or Since you know the lab you would be with, were you admitted before the visit weekend?
I am an applicant to the PhD program in ECE at Duke for Fall 2014. I have been invited to visit the campus to meet with the professors and in general get a sense of the work being done.
How positive a sign should I take this to be? Also, any suggestions, comments on how I can use this opportunity to make a good impression would be very welcome!
Thanks!
