“they say that it’s fairly easy, even the ‘harder’ majors like pre-med tracks.”
I think that you are going to find that premed classes get more difficult than you are expecting. For a premed student, there is nothing wrong with getting quite a few A’s (if you can do it).
To me it sounds like UNCC is affordable (if I am reading the thread correctly), you have been accepted, and it is a solid choice to get in the direction where you want to go, which is medical school.
It is not clear to me that you have any other path that is equally likely or more likely to give you a good chance to get to a medical school.
“out of state schools like University of Washington”
This is definitely not a safety. If you were “rejected by UNC twice” in-state then Washington OOS is probably a reach.
