I, like so many others that I know, have changed my major recently. I went from biomedical sciences to biology. I felt it was necessary and definitely not the end of the world. It’s a decision that is entirely up to you and your judgement, but I felt truly liberated. I went from a major that was demanding and specific to a major that was more open to interpretation and lenient.
I was super fortunate that I switched between sciences, meaning I was on track to graduate on time with either major.
It can be scary, no doubt. I’ve known people to completely switch tracks and refocus their priorities. I mean from business to biology. Changes like that do, unfortunately, mean more time in school. However, remember: time is relative. An extra year or two is nothing compared to a lifetime of happiness spent in your ideal career field.
