Help?!

Hi! So I graduate tomorrow and I’m going to end the year with a 2.81 GPA, while the total GPA of my first 3 years adds up to a 3.03 GPA. I’ve already been accepted to University of South Florida but I’m worried that this might cause them to revoke their acceptance.
(I’m normally a straight-B student but this year, I got an A and 2.5 Cs (.5 = semester class))

I can’t give great advice because i don’t work there but as long as you didn’t receive D’s or F’s I think you should be okay
