Should I apply for a primary care loan if I'm only about 80% sure about going into primary care? I can imagine my mind changing once I get more experience/knowledge about the other specialties.

Thanks!

From what I know about these loans, you should only accept them if you are 100% sure. The interest for these loans if you do not go into a primary care residency and then PC position (until it is paid off) is something like 18%, which is more like a credit card than a education loan (6-8%).
