Hypothetically of course

:
So based on what I have read about the GPA calculation, the LSDAS GPA is based on all of the courses that
apply toward your degree. Now, I am assuming that the body awarding one's degree is the one who decides what courses apply toward your degree. This is fine.
However, what if you are a transfer student? Say you transferred in 30+ hours to your graduating institution. For every transferred class that you have received an unsatisfactory grade, can you systematically retake these courses at your graduating institution to obtain a higher grade, and thus eliminate a course from transferring in? So now you would be transferring a 3.08 gpa at 27 hours, or a 3.2 gpa at 23hours and so forth?
I hope I explained this clearly. Thoughts?
Thanks,
