I don't really understand the conclusion that this is bad for non-science majors... If the test is aspiring to be more diverse/holistic, I'd argue that this is a benefit to liberally educated test-takers compared to dedicated science majors. I'd also argue that most humanities candidates take more courses than the bio/chem/orgo/physics minimums, and it's easy enough to make sure that these include cellbio, microbio, and biochem. Most libarts schools already require a course each in psychology/sociology/anthro so I doubt any changes would need to be seen in those departments. The reality is that it is actually pretty easy to finish gened reqs, premed reqs, and a 30 hour humanities major in 4 years, and not too much of a stretch to round up the premed reqs to a full science major in addition to the humanities one.
I disagree with the removal of the writing sample, as I'm already opposed to how little attention is paid to it.
