I have been 'attending' UC online for FNP since Jan 2010, and have one yr to go before graduation. Overall I am pleased with the quality of the education. Each quater is different and depends on the professors individual requirements. With that said, some are better than others. There have been classes where I have not had feedback from professors directly, but rather we were given a general class annnouncement to provide us with information about assignments (classes have about 200+ students). In other classes there was daily personal feedback. The pharmacy class was laughable...the information was outdated, and included meds that were removed from the market in 2007! Hopefully that will change.
This is a fast paced program so be prepared to spend many hours at the computer or with your nose in a thick book. IT was a hard adjustment for me, and I eventaully had to cut back to part-time at work. They love research and theory in the first year, but I have to admit the classes were engaging.
So far I have felt very postive about UC, and I've recommended them to some of my friends that want to return to school. Good luck to you
