In the four years since the more than 1,600 members of the Class of 2012 arrived at Duke, they have been changed by their university experience in ways large and small. Below are stories of nearly two dozen students who will graduate Sunday. Some have discovered unexpected intellectual passions or talents for making a difference in the local community. Others have had extraordinary experiences abroad. Five of these students were interviewed by Duke Magazine in 2008 about their hopes and expectations for a Duke education. Four years later the magazine returned to these students and looked at how their experiences compared with their expectations. Look for more about the Class of 2012 in the May 2012 issue of the magazine.
