Marwell is one of the most demanding professors I've had. She leads discussion sessions as if she was doing surgery--the result is clean, insightful comments that you will actually learn from, instead of suffering through. However, she is very nice and is very interested in the subject matter. As there is not a lot written on Latinos in NYC (suprisingly) and you do orriginal field research (ETHNOGRAPHY), you feel like you are actually contributing something. The reading, while heavy at times, was all facinating and well thought. Also, as there are no pre-reqs, you can talk your way in (as I did), which is rare for an ethnography class.
