The answer depends entirely on the college. Whether or not a university requires attendance or participation in religious activities like chapel or bible studies is up to each University or program individually. It is not uncommon for a Christian University to require things like chapel attendance or a certain number of "chapel credits."
The chapel credits system requires that students attend a certain number of approved chapel services or something similar by the end of each semester. Each of these services amounts to one chapel credit. This system allows students to choose the services or bible studies that best fit their schedule. Failure to complete the designated amount of chapel credits could result in a fine or other form of penalty, as ascribed by the college.
Some other colleges may require students to attend chapel services that are offered on specific days, as though it were a scheduled class. There are also many Christian Colleges will offer chapel services and other religious activities but leave attendance optional to the students. Check with the admissions office or on the official website of the college you are looking into to find out what their policy is on chapel attendance.
