Hello, I will be starting my junior year in fall as a biology major with a minor in chemistry. I entered college with a plan to apply to medical school. I have taken your basic classes for a biology major including genetics, ecology, cellular/molecular bio, chemistry, organic chemistry, and calculus 1. I have a 3.97 GPA. Throughout the past two years, I have developed an interest in science, particularly physics. I haven't taken any physics classes, but I am constantly drawn to the subject. I don't have any unrealistic expectations; I have done hours of research online and talked to multiple professors in the field. I understand the level of rigor that is involved with the math and physics classes, I'm not expecting to be learning about black holes and neutron stars. Being finished with my second year, however, I'm concerned about whether it would be worth switching at this point. Since I have only finished calc 1, I would almost be guaranteed to have to stay in school for at least an extra semester. However, I have been considering this for a year now and I figure if I've wanted to switch to physics for this long, it has to be more than a phase. I was wondering if anyone has been in this situation or has any helpful advice. Thank you.
