<p>Moschisms, I’m in the same boat. 3 B’s first semester, most ever in high school career, a little nervous, but hopefully USC will weight the fact that I took 6 AP’s in one semester, etc. Anyway, USC doesn’t send a letter requesting mid year grades. Your counselor uploads them via the common app. Also make sure to login to your USC portal, because there is a specific section there for you to input your mid year grades, as well.</p>
