Biostats is in the school of public health…which is a very competitive entrance. My D was accepted and turned it down when she realized it wasn’t what she wanted (I kept my disappointment to myself).
I agree about applying to additional schools in NC, if you have instate tuition.
A biology degree from UNC does come with employment options; some/a few are relatively well paying, while many others are not. You need to be assertive, resourceful, and realistic if you decide against medical school or any other type of grad school. Most bio majors end up continuing their education (my observation).
