Individual departments of the university may have centers or laboratories for the practical use of their students: For instance, the Department of Mathematics and Computer Science, located in the Cooper Science Complex, Building B, has a physics lab and two computer labs designed for the reinforcement of physics, physical science, and computer science techniques. The Departments of Psychology and Social Work share a computer laboratory located in Green Hall. The Department of Nursing has a clinical skills laboratory that provides simulated clinical practice, and a computer laboratory with test item databanks that assist students in preparing for the exit examination and the National Council Licensure Examination for Registered Nurses. Other departments have seminar rooms and places where students may use computers or get special assistance.
