Solved!

I am now enrolled in ANP 429: Ethnographic Field Methods. It's the required methods course for my anthro degree. I'll be learning different methods for studying populations, ethical issues involved, etc. And it's in the same room as my capstone course, ending twenty minutes before said course. I like minimizing transportation and transaction costs.
ANP 429 was on the slate for 2011-2012...so this way I can just wait around and hope that another religious studies course in Islam is offered that year.
