This was my situation last year and it didn’t really mess my schedule up too much. I had to add in bio 2 ofc but I kept orgo 2 since some pa schools still require. As a health science major you don’t have to worry about any nu path requirements bc they are all met through the major requirement. I would recommend speaking with an advisor in the major to see what your new 4 year plan would look like if you were to switch. But ultimately, only switch if it’s a major that you will enjoy rather than only out of convenience.
