I hold a B.S. in Biochemistry and an Associate in Science in Nursing. The B.S. in Biochemistry degree is, probably, the most difficult of all undergraduate degrees with relatively few being granted through out the U.S.A.. However, grading is extremely objective and fair as per the emphasis is on "Science" and the "Scientific Method" which is based upon objectivity. As I understand it, much of the first two years of medical school involve further course work in the sciences much of which I completed in my B.S. Degree. Pre-Med courses involve courses like Organic Chemistry, Quantitative Analysis, Calculus I, Physics, and Biology. The "Pre-Med" courses, therefore, are significantly harder than the Nursing Curriculum courses which, usually only involve General Chemistry,Algebra, and General Biology. However, the science courses that Medical Students must take in Medical School are MUCH harder than that in nursing school. As I remember it, medical students must take a national exam in the sciences, after the first two years of medical school and pass the same BEFORE they can progress to the next two years of medical school.Unfortunately, while in medical school the scientific method and medical reasoning are strongly emphasized, the same is not the case in nursing which still clings to "Nursing Diagnoses" which, essentially, abandons the same medical reasoning and scientific method condemning nursing to lose it's standing as a profession as the application of knowledge through reasoning is one of the requisites of a profession.
