If you’re a part of the 45% of students in the College of Arts and Sciences, you’re all too familiar with credits for CAEs — Creative Arts Experiences. They’re intended to help students become engaged in art, music, theater, film and literature on campus. For some reason, All-University Sing and Pigskin Revue don’t fall under this category, even though there are hundreds of participants every year — from Sing chairs and stagehands to sororities and fraternities.
