As I linked earlier, the nursing school students can take nursing classes at UVA Medical Center as a second year student. Here is a description of the classes (
http://www.nursing.virginia.edu/media/BSN_POS_06_14.pdf), you could reference these with the bursar website in order to get a description of where the classes are and what is learned. There are also nursing electives, which you similarly look up.
However, you would have to talk to someone from the program to get a gauge of interaction with staff and whether or not the two may have met prior. But, it seems unlikely that classes would interact with low-level assistants in a "classroom" setting. It was also only the third week of her second year; so, how much of a relationship would have developed at that point anyways?
FYI, anyone accusing me of being rude is taking things the wrong way. People are accusing others of crimes here without providing sound logic or evidence. This is not a good thing to do. If you are unfamiliar, please look up Richard Jewell, Sunil Tripathi, Salah Barhoum, etc. I am also here to discuss things, but claiming Hannah went to buy drugs or that this person killed her is not appropriate when there is no reason to say this.
