I agree. I have never seen nursing as an easy major. At my UG, it was extremely intense; however, I have heard this view expressed by adcom members themselves. Apparently, many feel that those majors are not "rigorous." I don't agree personally; however, the OP asked this question in terms of what med school adcoms want to see and many do not view health science coursework as rigorous. In some sense, I suppose I can see their pt in terms of the underlying sciences being very basic (i.e., many nursing majors only require 2 semesters of intro chem -- like the non-science major chem that covers gen chem 1 over 2 semesters -- and no ochem, biochem, etc.). Most of what makes those programs so intense are the clinical req'ts.
