How many hours does an intern commit a week? How is his or her time split up?

During the school year interns usually commit between 10 and 20 hours a week. In the summer interns may commit up to 40 hours a week, especially if the internship is paid. Some capstone or practicums have requirements of 240 hours total. Interns working on specific projects focus most of their time in that area, while interns working more generally split up their time evenly between different projects.
