UGA indicates in their admissions materials that they give GPA a higher
weighting. There has been a considerable grade inflation since the advent of Hope and possibly the advent of the "everyone wins" mentality. UGA's theory, apparently, is that someone with a great test score but average grades probably doesn't apply themselves in the classroom. Right or wrong, that's how they make the decisions.
To the original poster - the student should keep in mind that it is a whole lot easier to transfer in than to get accepted as a freshman. If the kid wants to go to Kennesaw, Georgia State, GCSU, etc. for a year to prove themselves, they can usually transfer in, and even if they went on the 5 year plan, in most cases that would be cheaper than going out of state.
