<p>For applicants how does USC calculate unweighted GPAs? On the A=90-100=4.0, B=80-89=3.0... scale, I have a 3.88. On the A=93-100=4.0 A-=90-92=3.7... scale, I have a 3.78. I've seen that their average GPA for Marshall is a 3.8, so frankly, I'm a bit worried.</p>
<p>id guess that for high school applicants, USC uses the basic A= 90-100 = 4.0, B = 80-89 = 3.0, etc. scale because thats what most high schools use. when you get into college is when A- counts as 3.7</p>
