Obtaining a master's degree in physics is feasible for someone with a biology background, but it requires meeting specific undergraduate prerequisites. Prospective students should review the admission requirements of their chosen institution, as there may be limited overlap between biology and physics courses. While some believe that a bachelor's degree in physics is necessary, particularly for teaching assistant positions, others argue that this is not a strict requirement at lower-tier universities. The discussion also raises the question of motivation for pursuing a physics degree, suggesting that potential students should consider their reasons for making this transition.
