Biophysics Major
Some universities offer undergraduate Bachelor of Arts or Bachelor of Science degrees in Biophysics, while others only offer a Biophysics degree at the graduate level (i.e., a master’s and/or doctorate degree). Biophysics degrees are heavily focused on physics and biophysics courses, and usually those who major in biophysics are required to take numerous math and…
