Sure has some earmarks of what might be a test:
Happened on a Friday early in the semester; classes won't be too affected by cancellations
Conditions in the Mid-East at this time make the threat one which is entirely believable
News sources apparently had very early word about the threat
Threats issued at about the same time to both schools; reports suggest both callers claimed to be Al-Qaeda
Both schools have two campuses - in Austin, the main campus and the JJ Pickles Research Campus; in Fargo, the main and the downtown campus
Two very different schools, UT-Austin and NDSU - thus perhaps different kinds of response....
....yet similar as well, as almost a straight line - within about a hundred miles - can be drawn between Austin and Fargo, with students from both sides of that line attending each school, creating a statistical similarity
