If you go for nursing, it’s a lot harder to get a job in the NY area- not sure about other areas- without a BSN.
PA is also another growing field- they’re rapidly supplanting GPs, apparently, in a lot of ways.
If you’re a chem major (which is what it sounds like), then you can always go into a lab sciences job for a few years before deciding what you want to do.
Also, make sure that you have all the prereqs for all of the careers you’re considering…
