What major are you looking at? What senior year classes do you have?
Do you have an ACT/SAT score? What proportion of your classes are AP, honors, and/or dual enrollment? Will you have 4 years of classes in each core area? (Eng, SS, Science, Math, FL)
I can’t chance you but need more info to help you categorize Clemson and UofSC(and even then, your HS GC will be in the best position to do that). No one here will know your essays or Letters of Rec, nor will any of the third party chancing calculators…so don’t do those!
