Unfortunately, they didn't reduce the rates. It was the same tuition price per semester, regardless of credit hours (as long as you still stay full-time, because the price for part-time is half). Which meant that people who graduated in quicker time spent less money. The cost was also the same for all undergrad degrees.

But it wasn't much of a concern at GT, because of the statewide Hope/Zell Miller scholarship covering the tuition based on the credit hours (and not on the actual semesters, you just have to have GPA high enough to qualify, which wasn't that high at all). So if you wanted to speedrun it and risk your GPA, you could do that. But if you wanted to take it slower, that scholarship allowed you to do so, because they paid regardless of how many years you took to graduate, as long as you were full time (with some nuances around part-time that aren't worth getting into right now), had high enough GPA, and you werent over the total cap of credit hours needed to graduate from your program.
