If it possible to say “You must complete courses A AND B before C”?
How about “You must complete one of A OR B before C”? (E.g. I have two different ways students can configure labs, and I want them to set up one way or the other before class, and then I can only show content relevant to the particular A or B that they chose as a prerequisite.)
I couldn’t find anything on the main docs. This Appsembler page implies you can only have a single prereq per class. But I don’t know if that’s a them-limitation or an overall Open edX limitation.
