I don't know about UT specifically, but in general any class you take at a college will count toward your GPA if you end up getting a degree there. If you took the pre-reqs somewhere else and are transferring
them to the school where you will ultimately be getting your nursing degree then they probably won't count towards your GPA.
But there are lots of other things to think about, too. If the grade is too low, it might not transfer to another school (depends on the school's guidelines for transfer credit). Also, if the grades are too low you might have a tough time getting into nursing school
And when you graduate, 2 GPAs are typically reported on your transcript: 1 for your overall GPA (all classes), and 1 GPA just for your Major (nursing classes only).
