The more demanding B.S. degree is a good choice for students who plan to do research and who may apply to a graduate program (or MD/PhD) in fields such as biology, biochemistry, bioengineering, biophysics, neurobiology, and physiology. The less demanding B.A. degree is a good choice for students who may prefer not to do research and who might be considering a career in clinical medicine, business, law, or consulting. But students interested in physics graduate school will be better off majoring in physics, the minimum requirements of the biophysics BS degree will not make you competitive for top physics graduate programs.
