If OP ever decides to apply to law school, the difference between a 3.60 undergrad GPA & a 3.57 GPA can have significance measured in ten of thousands of dollars.
Also, some law firms request more than just law school transcripts during the hiring process. Those that do tend to be very picky about grades and class rank.
And I do understand that law school is not currently in OP’s future plan thoughts. Other scholarships & programs may have GPA cut-offs and I doubt any such cut-off would occur at 3.57–more likely at 3.60 or some other round number.
P.S. Additionally, the LSDAS recalculates one’s undergraduate GPA for all law schools.
Furthermore, some federal government jobs have a class rank cut-off. The difference may well have an effect on whether or not OP makes the required cut-off of, for example, top 20%.
Finally, OP seems to want to take the other course in order to raise his GPA.
