not really. If you're part of a bible study group, it's in faculties, to make things easier. I guess that would seem like you're segregated by degree. But it's not exclusive. I'm leading a science faculty group (we have people who do med science/science/health science/psych degrees), but in an arts senior group.
when it comes to bigger events, like public meetings (talks) and camps, that's with EVERYONE across the whole uni. even people from the other campus'.
