Did she get merit from UofSC? They typically send a letter with admission with a guaranteed minimum. While they used to have “pretty good” merit, I’ve noticed it’s fallen a bit over the years with the rising popularity of the large southern U’s.
What others is she waiting on? If cost is an issue, then I would take out any college she can’t get to by car. The cost of travel has blown up, post Covid - having to pay to fly several times a year adds thousands to the cost.
What is her major? You mention grad/med school - if that is her route, then pick the cheapest option for undergrad, period, and keep that GPA up.
Did she apply to Wilmington? My D21 was rejected outright from UNC too, despite having the stats, so I can relate. Two of D’s friends did a year at Wilmington and then transferred to UNC sophomore year, so she can always go that route.
Mine is OOS at VT and I pay less than $50K (she has a small scholarship).
