When I was there I think it was in the neighborhood of 14 credit hours - basically a full semester of your coursework. As long as this is a mandatory requirement, and classes are being graded, this shouldn’t just be an easy A. Either these are serious classes with a legitimate purpose that requires them to be taught mandatorily in an academic setting, or they are just spiritual enrichment. But if the latter then don’t grade them, don’t make them mandatory. A’s aren’t just candy to hand out.
