The Wall Street Journal Health Blog discusses this issue. Here is the comment I posted:
I am all for weeding out people, but I think that the 2nd semester of O chem is a waste of time. Instead of a 2nd sem of O chem, I would require a semester of med-school level Biochemistry (and use this as a weed out course, in addition to the 1 semester of Ochem). I disagree with the previous comment of getting rid of physics. A basic knowledge of physics is helpful for many areas of medicine - neurophysiology (EEG/sleep studies), radiation oncology, nuclear radiology, and ophthalmology.
