Hi, all! To answer the questions posed above, the admissions folks have been really kind to me so far. My undergraduate degree was in . . . music! That's relevant. I graduated in 2008, so I have 5-6 years of work experience. My GRE was OK but I get the impression that they don't care about it much. I'm currently a program assistant on two epidemiological research studies, so my work is only kind of related to environmental science in general, although my main research interest is in pollutant exposure disparities. I took (and am still taking) most of the courses I completed from their recommended preparatory course list in a post-baccalaureate program since my undergraduate degree wasn't in the sciences. My SoP was two pages and I think it ended up exactly 600 words.
