I went to Univ of California-Berkeley in the early '50s, tuition was not quite free....it cost $15/semester.....student body card was an additional $10 but purchase not required. As far as I remember, a student body card let you into university sport events free. A year or two later, tuition cost $25/semester which included the student body card....the extra $10 hike to be applied to construction of a new student union. I later saw that new student union....it was beautiful....had a bowling alley and all the amenities a student could wish for. Cost was in the neighborhood of $25M.
