If you choose biology I would make sure to develop a strong resume while you are in college. Once you graduate there are jobs, but they won’t be high paying (lab work, research assistant, scribe, teaching etc). My daughter went this route and made enough to live in an expensive city with a roommate, but she is very, very frugal. She spent 2 years shadowing, observing, and interviewing doctors, NPs, PhDs, etc before deciding on her path. Most biology majors move on to some type of grad/professional school.
A nursing major will lead to a good job after college, but you have to like this type of work. If you don’t, all is not lost. You can work as an RN and get an advanced degree to become a NP- different type of work, but once again you have to like it. An NP is not a physician. You can be involved in research as an NP- it’s not one or the other.
A biology degree can lead to all different types of career paths- MD, PhD, PA, NP, genetic counselor, teaching, etc. This might be good if you are unsure about nursing.
Only you can decide, and I wish you luck!
