I am a 20 year old Chemistry major who is currently finishing up his junior year of college. My initial plan was to graduate with a Chemistry BA and then proceed to apply to medical school. However, after taking physics non-calc based 1 & 2 I remembered how much I enjoy the physics. I am currently thinking of switching from chemistry to physics, however changing my major would be very difficult. I would have to stay an extra semester (so 3 more in total), and I would have to take the following courses: Calc 3, Differential Equations, Partial Differential Equations, Quantum Mechanics, Electromagnetism 1 & 2, Sophomore Lab, Junior Lab, and Modern Physics. All of these courses would have to be completed within 3 semesters. However, the road to completing my Chemistry BA will also be quite hard as I focused on fulfilling my medical school requirements first before doing anything else so I am not even that far into my major. I have only taken Chem 1 & 2, Organic Chem 1& 2, and Organic Chem Lab. This means if I want to finish my chem degree I will also have to cram in a lot of hard chemistry courses. To me, receiving a degree in Physics seems like a good idea because just in case I do not go to medical school or decide I do not want to go, I could always fall back on my Physics education and look for a job that interests me. This is in contrast with Chemistry, as I do not feel I would enjoy being a Chemist. In closing, do you think it would be a good idea to switch from Chemistry to Physics? I do not truly know if I would enjoy the upper level Physics/Math courses as my knowledge and enjoyment of the subject is limited to the introductory courses. Edit: How do I move this Academic Guidance? Sorry.
