Do you have to go pre-med in order get your Ph.D?

No, you do not have to go pre-med to get a Ph.D. Pre-med is a specific undergraduate track designed to prepare students for medical school (MD or DO). A Ph.D. is a doctoral degree focused on research and is awarded in a wide variety of disciplines, including but not limited to: sciences (biology, chemistry, physics), humanities, social sciences, and engineering. While some Ph.D. programs in biomedical sciences might benefit from pre-med coursework, it's not a requirement. The necessary undergraduate preparation will vary greatly depending on the specific Ph.D. program.
