What are my chances of getting into USC Marshall?

I am currently a high school junior. I received a 1450 on the sat (690 reading and writing, 760 math). I am also the co captain of my robotics team and am in charge of collected finances and sponsors for my team. I am also the treasurer of my Coding Team. The main thing I am concerned about is my GPA. I have a 3.71 (which meets USC average) however I am a B math student with a C+ (79%). I am doing well in AP Macroeconomics and have a strong interest in business. What are the chances I get in even with my mediocre Math grades. Will my high SAT math make up for it? Does USC Marshall make exceptions in the application process?

Side Question: How hard is it to transfer into Marshall as a USC student.
