I'm curious--have you decided to go ahead with UW's program? I was also accepted into the RN/BSN curriculum earlier this summer and am looking forward to starting UW classes next week. Like you, I've found communication to be a bit of an issue--but I've also been impressed at how different faculty/staff will absolutely go out of their way to try to accommodate my questions, etc. And, based on my research, UW is very definitely a good university.
From my (albeit rather limited!) contact with the nursing department, I've concluded that I must 1.) be as persistent as necessary with phone calls/questions until I have good answers and 2.) basically take responsibility for doing my own advising. --Not that that is necessarily such a bad thing--it just forces a person to take a bit more ownership of his education! =) If it is of any help to you, I've found the Advisor and Coordinator of the RN/BSN program to be incredibly helpful. Best wishes!!
